Haworth Tompkins Ltd 3 4 Battersea Arts Centre HLF Stage D Report June 2012 DESIGN REPORT

“The vision for Battersea Arts Centre (BAC) is to champion the exploration of our history in order to help invent our future. For example, one of BAC’s strengths is that it is not based in a purpose built theatre but in a building with a great heritage and strong civic values: its spaces act as a provocation for artists who are looking to reinvent the rules of theatre. We think it is one of the reasons why BAC has housed some of the UK’s most innovative and brilliant theatre artists over more than 30 years. It is also the reason why we want the building to continue to enable creative congregation and collaboration, a home for young and old to come together, hosting thousands of different events every year, a model for resilient theatres of the future that encourage neighbourliness, empathy and civic pride. We want to create a space that provides a home, where artists and audiences can prepare food and eat together. We want BAC to reveal itself gradually, like an exciting story, rewarding those who peek behind the curtain, breaking the barriers between ‘front of house’ and ‘back stage’. We think that project will help identify new ways in which cultural organisations can bring heritage to life: not simply in terms of illustration but in the way that heritage informs our future.”

David Jubb & David Micklem, BAC Joint Artistic Directors

Haworth Tompkins Ltd 5 1 EXECUTIVE SUMMARY This report has been compiled by Haworth Tompkins Architects, in collaboration with Battersea Arts Centre (BAC) and the Design Team. It forms part of the second round submission for Heritage Lottery Funding. Battersea Arts Centre was approved for the first round development phase in June 2010. This document comprises the Design Report and the Technical Report for the proposals equivalent to RIBA Stage D.

Battersea Arts Centre (BAC) is housed in a Grade II* listed Victorian Town Hall. The building is of significant note for its architectural, political, social and creative heritage. The proposed works to the building presented in this report will conserve the building’s historic features and improve facilities and access so that more people can enjoy and appreciate them, continuing the long history of community engagement which is already part of the Old Town Hall. The building itself is a magnificent example of Victorian architecture and a well-known and loved landmark on Lavender Hill. Inside the building contains a wealth of spaces, each having its own character, with grand rooms and entrances leading to intriguing corridors and intimate corners. The project involves not just the conservation of this valuable heritage, but acts as a beacon, bringing together and revealing the heritage of the wider area.

The proposals comprise five elements:

- Access improvements to the building, which include both physical and intellectual elements. The BAC archive is to be digitised and new viewing pods created in the foyer in order that visitors can learn about and interact with the building. The accessibility of public entry points to the building is to be improved with new ramps and lighting. An induction loop is to be located at the Box office and Braille signage installed in public areas. A new platform lift will link Lower Hall and Grand Hall level, creating accessible circulation throughout lower levels, ground and first floors.

- Restoration of elements of significant heritage value, which include restoring the Hope- Jones Organ in the Grand Hall, the original glass mosaic flooring and the glazed Octagonal dome. The Grand Hall entrance canopy and Theatre Street lantern will also be restored.

- Town Hall Road, a private road adjacent to the building within BAC’s lease, is to be relandscaped to create outdoor public space, enhancing the way this important building is presented to and used by its community. New signage is proposed to the bar entrance above: View of Town Hall Road below: Event on main steps

6 Battersea Arts Centre HLF Stage D Report June 2012 on Town Hall Road, indicating this entrance and encouraging new visitors. The proposals will also enable an expansion of uses linked to BAC activities and make environmental improvements to the wider area.

- The Lower Hall level is to be remodeled to create improved facilities for users of the Lower Hall, increasing its appeal and use for a large number of different groups. This will enable wider appreciation of the Lower Hall itself, which is decorated with the Battersea motto and crest. Also at Lower Hall level, an enlarged office space will be created which is to be rented out to creative start-ups. In addition, the Lower Hall will make a greater contribution to BAC’s income generation capacity.

- Conservation and upgrades to the historic building fabric. These works comprise essential repairs to the brickwork, stonework and roofs and the removal of non-original external features such as the projection box and external cabling to enhance the appearance of the building and return it closer to its original state. Fabric upgrades which will improve the energy efficiency of the building and reduce its carbon footprint are also to be made, including insulating the roofs, new double glazing to windows and rooflights, draught- proofing to doors and the installation of two new wood-burning stoves.

The works detailed in this report form part of a wider masterplan for the building that proposes rationalisation, refurbishment and extension to existing internal facilities and the replacement and upgrade of the building services infrastructure. These wider proposals have been developed alongside the HLF works to Stage C. A summary of the proposals is included in Appendix F.

This report is to be read in conjunction with the Conservation Management Plan for the Building and Archives, the 10 year Management and Maintenance Plan, Project Execution Plan, Activity Plan and other documents which form part of the HLF submission. Relative Sensitivity Analysis Drawings from the Conservation Management Plan are included in Appendix E of this report.

Haworth Tompkins Ltd 7 2 vision and aims BAC is a revenue funded arts organisation, founded in 1980. It has grown synonymous over the years with the building housing it, Battersea Old Town Hall, on Lavender Hill in southwest London. It is highly acclaimed for its innovative approach to theatre making and for the many successful artists who continue to emerge through its doors. BAC aims to create and promote exciting, high quality, risk-taking arts activity through creative collaborations between artists, staff and public.

While theatre making and performance are central to BAC, it also forms a hub for the local community, with a number of other activities take place within the building. There is a café and a very popular under 5s play space, both adjacent to the foyer and open to the public daily. The Council Chamber and Grand Hall are used for performances as well as being hired for events such as weddings and conferences. There is a programme of activities with local schools, which take place in the Grand Hall and the Lower Hall. Other independent classes, such as Weight-watchers, yoga and after-school clubs also use the building. At any one time, the building therefore houses a variety activities and people, creating chance encounters and unusual juxtapositions. BAC aims to increase the number and range of

Haworth Tompkins Ltd 9 3 the old town hall Battersea Town Hall was completed in 1893. It was designed by E W Mountford, architect of the Old Bailey, and nearby Battersea Central Library. It was listed at Grade II* in 1970 and of great significance for both its architectural qualities and its part in the social and political history of Battersea.

The Town Hall is located on a sloping site, with the Municipal building to the south fronting onto Lavender Hill, and the Grand Hall – a space designed for public assembly - to the north,

Town Hall Road situated half a storey below the main ground floor level. There is a clear division in massing directly related to the intended functions, although it presents a continuous façade to the surrounding four streets. The exterior is of red Suffolk brick, with Bath stone dressings. The

Theatre Street BAC original roofs were of Westmoreland slate, but the Grand Hall roof and roof to the south and west wings of the Municipal building have been replaced with clay pantiles. The imposing south elevation is in free Classical style, with the east and west sides and north elevation treated in Arts and Crafts style.

Lavender Hill Internally, the Municipal building contains a number of fine rooms, arranged around a central courtyard with brings light and air into the building. The public spaces are linked N by blue glass mosaic floor with decorative borders. In the main foyer area a beemotif is also included in the mosaic. The Council Chamber is the finest room in this part of the building, with a strapwork ceiling and panelling to the walls, and tall arched windows containing leaded lights. The other ground and first floor rooms are of good proportions and generally retain the original cornices and floors largely intact. A number of local craftsmen and businesses were employed in the construction of the original building.

The Grand Hall building lies to the north of the Municipal building. It houses a public hall of an unusually large size which the Vestry of Battersea felt would benefit the local community when it was built. From the early 1900s, the Hall staged talent contests, traditional jazz performances and musical evenings. The room has an elaborate barrel-vaulted ceiling and frieze over the proscenium arch to the stage, with windows at high level and doors along both sides giving access to circulation space. The Grand Hall organ was installed in 1901, and is of great historical significance, as it is the largest and most original example of an organ designed by Robert Hope-Jones. The Lower Hall is located beneath the Grand Hall, to the north of the site. above: Site plan below: Aerial view of BAC showing Municipal building to the south and Grand Hall to the north

Haworth Tompkins Ltd 11 There have been a number of alterations to the building during its life. One of the most significant was only six years after it first opened, when the ‘red staircase’ wasadded along with the first floor rooms on the west wing of the Municipal building. Over the years rooms have been partitioned and re-partitioned to create rooms of varying sizes to meet the changing requirements of first the civic, and then the cultural, functions of the building. When the organ was installed, modifications were made to the Lower Hall rooms in order to accommodate its vast apparatus. The Lower Hall was altered in 1936, when the original columns were removed. This necessitated the deep beams that are now a prominent feature of the room, which include the Battersea motto, ‘Not for you, Not for me, But for Us’.

Battersea Town Hall functioned until 1965, when the Town Hall was relocated to its current site on Wandsworth High Street, following the creation of the borough of Wandsworth by the London Government Act 1963. During its time as a Town Hall, the building witnessed a number of historic events, including the election of London’s first black mayor. During the First and Second World Wars, the building was used as a recruiting station and administrative centre. During the First World War it was also used as a conscientious objectors’ tribunal site. A Conservation Management Plan for the building has been written, which examines its architectural and cultural significance and gives a detailed analysis of the different elements of the building. The Plan identifies the risks and opportunities associated with the ongoing upkeep and use of the building and provides the framework within which any future repair, alterations and additions to the built fabric should be developed. The Plan has been produced by Haworth Tompkins in consultation with BAC, English Heritage and Wandsworth Borough Council, and will be made available to the public on the BAC website. It has been used to develop the wider masterplan for the building and the scope of the HLF works.

12 Battersea Arts Centre HLF Stage D Report June 2012 Haworth Tompkins Ltd 13 The Statement of Significance included in the Conservation Management Plan isas follows:

Architectural As a Grade II* listed building BAC has been designated a building of important and special architectural interest. The Old Town Hall is an attractive example of late Victorian municipal architecture, built with great skill and craftsmanship, designed by an architect of considerable repute and is a good example of Mountford’s work. It has its own very special character and beautiful ‘set-pieces’, which make it unique and significant. The use of local artisans mean the building’s finer detail is rich in historical and social significance. The architecture is made more interesting by the need to accommodate its sloping site, which gives a pleasing complexity of plan and creates the possibility of separating the Municipal building from the Grand Hall. The spacious arrangement of the building and the generous, day lit, wide corridors off the central Court and flanking the Grand Hall contribute to the successful varied occupations of the building. The Council Chamber, the Grand staircase, the Grand Hall and entrance halls are beautiful and finely detailed spaces, well suited to entertainment purposes. Key heritage assets include the Octagonal Dome, the mosaic floors and the Robert Hope-Jones organ.

Political The building has been the home of revolutionary ideas and thinkers since it was opened, reflecting what historian Sandra Wallman calls “Batterseaness.” As the Town Hall, and as such the centre of civic function in the borough, it played host to several radical groups and thinkers over its first 80 years of existence. This was then echoed in its creative function, with several radical political performances being hosted at the building from 1980 onwards. It played host to the first Black mayor of a London Borough, John Archer, radical feminist thinkers Caroline Ganley and Charlotte Despard and key labour voices such as John Burns.

14 Battersea Arts Centre HLF Stage D Report June 2012 Social As a Town Hall until 1965 the building played an incredibly important social role in the community; with constituents attending the building for administrative purposes as well as for their leisure and the Grand Hall having always been a site of Concerts, Bazaars, Debating Societies, University Extension Lectures and Recreative entertainments of a high-class for the people. Under BAC’s stewardship the building continues to provide participatory and community activities for the local area. Several local people have fond memories of the building and through its use for weddings, exams, memorials, elections and community gatherings it continues to be a place of many ‘firsts.’

Creative Battersea Arts Centre is well known for being at the cutting edge of contemporary British performance. Since it was established in 1980 it has played host to some of the most influential companies in the UK and pioneered new approaches to making work, such as Scratch and artist residencies. Several prominent performance companies got their start at BAC or worked with the arts centre before they were established voices in the theatre world. BAC helped develop and raise the profiles of these innovative groups. Through its unique approach to theatrical process and working with artists, BAC continues to be at the forefront of new developments in theatre practice in the UK and internationally.

Haworth Tompkins Ltd 15 4 development of the scope of works The scope of the proposed works in the first round application was based on BAC’s key priorities for conserving its building and opening up its heritage to the public. These comprised increasing the level of accessibility, conserving and restoring the building’s most significant internal features, making urgent repairs to the building fabric and improving the environmental and economic sustainability of the building. While these priorities remain unchanged, there have been some revisions to the scope of works since the first round submission.

BAC has commissioned a Design Team, led by Haworth Tompkins, to develop a masterplan for the building in order to provide a wider context for the works. BAC has also secured Arts Council Renew funding which has enabled some pressing works to be undertaken. In addition to this, during the second round development, BAC has consulted HLF on the scope. Following this, the addition of works to improve access and facilities to the Lower Hall and an increased scope of works to Town Hall Road have been included in place of full replacement of the roofs. Bringing in the works to the Lower Hall opens up this significant space, decorated with Battersea’s motto and crest, to the community and for use by local start-up companies.

Other additions are works to restore the external Theatre Street lantern, included following consultation with English Heritage and Wandsworth Conservation Department; the restoration of the Grand Hall canopy, which will revitalise one of the main entrances and improve revenue from weddings and other hires; and fabric upgrades to reduce the building’s energy consumption and running costs.

Haworth Tompkins Ltd 17 During this period, BAC has examined the options for storing and accessing their archive, and have formed a partnership with Wandsworth Borough Council, who will house the physical archive. The archive for the building is currently stored at Wandsworth Library, and this will unite the two collections. It is proposed that the BAC archive is digitised, with public access to the digital archive available at BAC through interactive viewing locations in the foyer.

The masterplan developed by Haworth Tompkins and the Design Team has resulted in some omissions to the HLF scope of works. Elements that would strategically fit better with other planned phases of works are decorations to the building, repairs to the basement and the internal works to the reception area.

The Arts Council Renew funding secured by BAC has enabled a number of projects to be undertaken to improve particular aspects of the building that are linked to performances or events. It has therefore been possible to complete the works to the Council Chamber, decoration to the Grand Hall, West wing strip out works and Member’s Library/Cloakroom doors. Works to the Council Chamber were made a priority due to the revenue impact that they would have, a decision which has seen successful results with increased bookings.

Grand Hall ventilation has been omitted following BAC successfully testing nautral ventilation strategies in the space. This is considered a more sustainable approach.

Haworth Tompkins Ltd 25 5.2 Restoration of significant heritage

5.2.1 Restoration of internal elements of significance

Organ

The Grand Hall organ was designed by organ pioneer Robert Hope-Jones and installed in 1901. It is of great heritage significance as it is almost definitely the largest and most original example of Hope-Jones’ work that survives in the country. The organ was built into the stage area and has five separate carved woodwork cases containing the five sections. Its full restoration is included as part of these works. An organ specialist has previously undertaken partial restoration, and it will now be returned to full working order.

Glass Mosaic

The 1893 Inauguration ceremony text notes that the enriched vitreous glass mosaic was by the Vitreous Mosaic Company. The tiles are used throughout the public areas and in the main foyer space a decorative bee motif is used. In the ground floor area there are also elaborate floral borders. The tiles are generally in good condition, but require replacement in some areas. The replacement tiles for more prominent areas will be taken from less frequently used back of house areas.

Haworth Tompkins Ltd 27 5.2.2 Restoration of external elements of significance

Octagonal Dome

The glazed Octagonal Dome is situated above the entrance hall to the Grand Hall and appears to be part of Mountford’s original design. It is octagonal in plan with eight identical faces consisting of twelve rectangular leaded stained glass panels, depicting a central vase with surrounding trellis and leaves. The panels are supported on a cast iron framework. The ventilation cap is not original.

The dome has been poorly repaired in the past and currently leaks. A full specialist restoration is proposed, which will include dismantling the dome and restoring each part individually. The existing ventilation strategy, which provided ventilation at the joints, will be reinstated and the ventilation cap removed. The internal experience of the glazing will be improved by the removal of the external projection box which currently casts a shadow across it.

28 Battersea Arts Centre HLF Stage D Report June 2012 Grand Hall Canopy, Streetlights and Theatre Street lantern

The cast iron decorative canopy to the Grand Hall was added in 1905 and is a prominent decorative feature of the east elevation. The entrance is used for events in the Grand Hall, including weddings. It is currently in a reasonably good state of repair, but is missing some details. These are to be replaced to match the existing. The canopy columns are to be modified to suit the proposed Grand Hall entrance ramp and steps with new cylindrical surrounds fitted at the bases.

There are eight historic streetlights to the south and east frontage of the Town Hall. Two of these require significant repair, which will be part of these works. The four on Town Hall Road will be relocated to suit the new pavement line.

The existing decorative bracket for the lantern on Theatre Street will be repainted and the lamp brought back into working condition.

Haworth Tompkins Ltd 29 5.3 Town Hall Road

The proposals transform the setting of the Old Town Hall, creating outdoor public spaces linked directly to the building on Town Hall Road. The proposals also enhance BAC as a destination not just for theatre, but as a heritage asset, increasing its visibility and welcome, and opening it up to more audiences. The road will be relandscaped and a level surface created. The portion of road in front of the east elevation will be pedestrianised, with removable bollards allowing vehicle access when required. New ramps will be provided to the public entrances to the building. The balustrade of the ramp to the bar entrance forms a new piece of signage that serves to enliven the area and increases the street presence of BAC. The balustrade sign is formed of a red-painted steel beam with the letters ‘Battersea Arts Centre’ cut out and back lit. This forms an integral part of the entrance to Town Hall Road and a new distinctive guide into the building.

Along the length of Town Hall Road there are four proposed surface treatments that delineate areas for different uses, shown in the plan opposite.

The existing York stone pavement area to the southern part of Town Hall Road is to be retained and extended with reclaimed pavers, maintaining a clear formal route to the Grand Hall. This route is planted with birch and fruit trees on the other side of the road, enhancing the setting of the Grand Hall entrance and creating a buffer to neighbouring properties. The existing streetlights are to be relocated to sit at the edge of the new pavement line. York stone paving is to be laid on the new ramps to the bar entrance and the Grand Hall entrance, creating an integrated paved surface which rises up to the entrances and falls as demanded by the sloping site conditions. The Grand Hall entrance has a generous paved platform in front of both sets of double doors. The existing metal ramp to the Grand Hall which serves only one set of doors is removed.

An outdoor seating area is proposed at the Lavender Hill end of Town Hall Road. York stone setts are to be laid here, matching the existing York stone paving but suitable for vehicular traffic when required. The two existing red telephone boxes will be retained and planters installed along the boundary following the same line. The use of the road by vehicles will be

Proposed lower and upper Town Hall Road plans

Haworth Tompkins Ltd 33 controlled by BAC and the road will be closed when this area is in use.

The third portion of road is laid with resin-bound crushed stone topping over the tarmac, softening its appearance. This area runs from the Grand Hall entrance to Theatre Street. The existing pavement is replaced with the same topping and reduced in height to create a continuous surface with the road. The area is thus widened for public use. Direct access is available from the Lower Hall, and this area will be connected with the community activities that take place in the Lower Hall. New streetlighting and external lighting mounted on the building is provided to this area.

The existing concrete paving is retained in front of the north elevation. This surface treatment is extended to the east elevation where a new level entrance to the Lower Hall is created. The levels of the existing paving are modified in front of the relocated entrance to the Lower Hall foyer to create level access. Bike stands are to be installed to the west end of the road.

Town Hall Road is an unadopted highway with a 2m wide adopted portion to the eastern boundary that will be maintained as a public right of way at all times. A 3m clear one- way road width is maintained along the length of Town Hall Road. Two dedicated disabled parking bays are to be created in front of the Lower Hall entrance. There is a turning head so that cars using these spaces can turn around and exit along Theatre Street. A coach drop off point is located at the end of the road. New enclosed bin storage will also be provided at this end of Town Hall Road.

Proposals to Theatre Street and Lavender Hill external areas are discussed in section 5.1.

Haworth Tompkins Ltd 37 5.4 Lower Hall

The Lower Hall was originally created for community uses. It is located at the north of the building, below the Grand Hall. It is decorated with the Battersea motto ‘Non Mihi, Non Tibi, Sed Nobis’ (‘Not for you, Not for me, But for us’). BAC hire out the Lower Hall to a number of different community users for classes and events. The Hall itself is being refurbished by BAC with Renew funding over summer 2012, but the ancillary areas are in need of alteration and refurbishment in order to meet the needs of BAC and their hirers. The space is a valuable asset to BAC and it is hoped that the uses of this hall can be expanded once improvements to its facilities have taken place.

As part of the HLF proposals, the Lower Hall main entrance is to be relocated to its original position. The existing stone surround to the opening remains, but has been bricked up. This will be opened up and a new lobby to the foyer created. Internally, the foyer area is to be reconfigured to create a reception area with seating. A new window will be installed where the current entrance has been infilled, bringing natural light into the space. Changing areas and a new accessible wc will be provided and the existing wcs refurbished.

A new platform lift linking the Lower Hall to the Grand Hall level is proposed. This will enable accessible circulation from the Lower Hall to the first floor level. There is currently a chair lift from Grand Hall to ground floor level and a lift at the front of the building linking ground and first floors. The Lower Hall to first floor levels will therefore be fully accessible from the disabled parking spaces on Town Hall Road.

The existing offices at Lower Hall level are used by BAC staff. Within the wider masterplan, new offices for all staff in the west wing attic spaces are to be created, freeing up this space. The Lower Hall office space will be let to creative start-ups, who can contribute to the life of the BAC community. It is proposed that the office space is expanded to include part of the now defunct Lower Hall kitchen. A storage area for the Lower Hall will be created in the other part. The office is to be fitted with new lighting, heating and ventilation and will become a new stream of revenue for BAC, also serving to bring new people into the building. A new kitchen for shared use by the Lower Hall and offices is located between the two rooms. Additional wall and ceiling linings to the office will isolate it acoustically from the activities in the Lower Hall. The door to the Lower Hall will also be fitted with an additional acoustic above: Photographs of Lower Hall as existing below: Section showing Grand Hall and Lower Hall relationship shutter to separate the hall from the foyer during noise sensitive activities.

Haworth Tompkins Ltd 41 5.5 Conservation and Upgrades

5.5.1 External repairs

The existing red Suffolk bricks are badly weathered in some areas, particularly on the east elevation. Poor repairs with unsuitable mortar have further exacerbated problems. Areas requiring urgent repair, including chimneys, have been scheduled and will be undertaken. Works involve repointing and some replacement.

The existing stonework, including surrounds to external doors, stone courses and stone cappings have weathered badly in some areas. Areas requiring repair or replacement have been scheduled and where necessary stonework will be replaced or indented.

The existing roof slates and tiles are in reasonable condition but there are some areas which leak and repairs will be undertaken locally. Replacement of lead flashings, cast iron down pipes and gutters and leadwork to dormers and turrets is proposed where required. Asphalt coverings to the flat roof of the Grand Hall link area are to be replaced.

The non-original projection box to the Grand Hall roof and the white timber boxes over the Grand Hall fans openings are to be removed. Redundant external cabling will be removed.

5.5.2 Sustainability upgrades to the existing building fabric

Upgrades to the building fabric are to be made to reduce energy consumption and the carbon footprint of the building. Roof insulation is to be installed over the ceiling in the Council Chamber and Recreation Room and at rafter level in the remaining attic spaces. Insulation will also be installed to the Grand Hall flat roofs.

42 Battersea Arts Centre HLF Stage D Report June 2012 The timber sash windows to ground floor and first floor public spaces will be upgraded with double glazing. The ‘slimlite’ system is to be used, with double glazed units fitted into the existing timber frames to preserve the original appearance. In the Council Chamber, the leaded light windows will be secondary glazed with perspex sheet to minimise visual impact.

External doors are to be draught-proofed.

Two new woodburning stoves are proposed in the Member’s Library and the New Committee Room. These are in addition to the two recently installed in the Surveyor’s Department and the Waiting Room. The stoves will be fuelled by scrap wood, a renewable energy source, and reduce demand on non-renewable energy fuelled heating.

Haworth Tompkins Ltd 43 6 PROGRAMME & PROCUREMENT The proposed programme is shown opposite. The works will be submitted for Planning and Listed Building consent following the submission of the HLF application.

On condition of funding approval, the works will be developed to Stage E between October 2012 and January 2013 and to Stage F between February and May 2013. The works will be tendered in June 2013 and it is intended that the main works start on site in September 2013. It is estimated that the construction period will be nine months.

It is intended to let the works as a single contract, with the exception of the specialist organ works. These will be procured directly by BAC, and they would take place prior to the main contract works.

The sequencing of the works will be developed at Stage E. The building will remain occupied during the works. While it is appreciated that the works will be a significant factor in BAC’s programming, it is intended to reduce their impact to a minimum. A phased approach with sectional completion for the internal works is likely to be considered.

Bollingbrook 2501 / BC 7 STATUTORY AUTHORITIES 7.1 Planning

BAC and Haworth Tompkins have attended a pre-planning meeting with the planning officer, conservation officer and highways officer at Wandsworth Borough Council planning department. The planning authority are supportive of the proposals, and have provided formal feedback to this effect, included in Appendix G.

English Heritage have also been consulted on the proposals and are supportive.

7.2 Building Control

As part of Part L building regulations, the Services Consultants have produced a guidance notes on the building fabric performance, which is included in the Services section of the Technical Report. The proposals include upgrades to the existing fabric, including insulation and double glazing. These are in line with Part L2 guidance on consequential improvements. As a listed building, there are times at which upgrades could negatively impact the historic significance of the building, in which case an alternative will be found, or they will not be implemented.

An access audit has been carried out, the summary findings of which are included in Appendix E. New ramps have been designed in accordance with Part M where possible within the context of the existing building. A new accessible wc is to be provided at Lower Hall level, where there is currently no provision.

The proposals do not make significant alterations to structure or fire safety strategies. In the Lower Hall, the fire detection system will be modified to suit the new layout.

Mechanical Ventilation to the new office is proposed in order to adequately ventilate the deep plan space.
