03 SITE AND URBAN CONTEXT
03.1 LOCAL AREA
The site is located off Marshalsea Road and Borough High Street. It is within walking distance of major cultural landmarks such as Thames Riverside, Borough Market, The Tate Modern, The Old and Young Vic Theatres and the City of London.
There are a variety of building styles along the surrounded streets; residential, offices and retail of differing styles and materials contributing to the vibrancy of the area.

04 AREA AND SITE ANALYSIS
04.1 AREA ANALYSIS
The site is located behind Marshalsea Road, between Borough Station and Mint Street Park.
The wider area mainly consists of residential buildings in a range of scale mainly around 5 storeys.
There are several recently approved applications for new residential developments in the surrounding area that have been identified on the left, many of which being roof extensions. These applications provide a clear precedent of how existing sites can be optimized in a sustainable manner.
Planning Application Design and Access Statement gml architects 7 November 2020 55 Lant Street, London
04.2 SITE ANALYSIS
The site sits along the former route of Lant Street previously occupied by the Charles Dickens School, to the south. To the north, Peabody Douglas Buildings form an enclosed courtyard.

05 SITE AND URBAN CONTEXT
05.3 FLOOD RISK 05.1 BUILDING HEIGHTS The proposed development area is located in a The immediately surrounding buildings are medium risk Flood Zone 2 area as can be seen on predominantly 3-4 storeys with some 5-6 storeys. the Environmental Agency flood plain map (2018) The tallest building near the site is Redman House; below. Given that the proposals set out here are for a 13-storey residential block south east of the site. a rooftop extension to an existing building, the risk The Rise housing on the corner of Lant Street and of flooding is not a material consideration. Sanctuary Street is another example of a taller building in the area.

Some possible, reflecting the high level of public transport. of the adjacent buildings are mixed use; residential The site is approximately 3 minutes walk away and commercial. However, the wider area to the from Borough Tube Station and 10minutes walk south and north is populated with a large number of away from London Bridge Station. Bus routes also commercial and community buildings. operate from various existing bus stops located on Borough High St. and Southwark Bridge Rd. (35 343 345 C10 344).
Planning Application Design and Access Statement gml architects 9 November 2020 55 Lant Street, London
05.5. CONSERVATION AREA
The Liberty of the Mint Conservation Area is situated, broadly, to the west and south of Borough Tube Station. The conservation area contains much of the site of Brandon House/ Suffolk Place, the former palace of the Dukes of Suffolk.
The Liberty of the Mint Conservation Area contains a varied section of Southwark townscape broadly dating from the later 19th century. This consists of a mix of industrial, residential, educational, transport and historic, mixed-use buildings fronting onto Borough High Street. Much of the Marshalsea Road area has been subject to substantial rebuilding in 1888.
The southern parts of the conservation area retain much of the Victorian character of closely packed former industrial and residential buildings defining a tight, well-defined townscape. The wider area has had significant archaeological investigation, though given the rooftop nature of this application, there would be no impact on any archaeological remains associated with these proposals. 15.

07 DESIGN STRATEGY
07.1 PRE APPLICATION
Pre-application advice was initially sought from the local FIRST PROPOSED STRATEGY authority in September 2018 for a scheme including a predominantly two storey roof extension, with a centrally located 3 storey element.
Following officer feedback a revised pre-application submission was made in December for a reduced scheme with the 3rd storey element removed.
Since then the scheme has been reduced further to a single storey extension.

07.2 WITHDRAWN APPLICATION
20/AP/1272 - The application was withdrawn on advice from planning officers.
Erection of one additional storey on each of the three existing residential blocks to create 16 no. residential units and the provision of one additional bedroom to an existing residential unit in Block C, including a new roof terrace, and associated waste and cycle storage at basement and ground floor level.
The new application reduces overall massing, height and completely removes proposed extension to Block C.
Planning Application Design and Access Statement gml architects 15 November 2020 55 Lant Street, London
07.3 CONCEPT
The following diagram illustrates how the proposed approach has emerged from a clear set of principles and responses to the context, including:
• Height responding to old and new context; maximising site potential with minimal impact.
• Background to increase density in suitable locations.
• Add accommodation to existing buildings with a one storey roof extension including a strategically positioned taller element as a focal point in the centre of the site
• Use additional roof extension to improve proportions and reduce appearance of depth of existing buildings which are relatively wide and flat with minimal detailing or focus.
07.4 MASSING
The massing has been designed to respond to the individual aspects of the site such as surrounding context, heights of existing buildings to neighbours and views into the site and daylight.
Planning Application Design and Access Statement gml architects 16 November 2020 55 Lant Street, London
07.5 PROPOSED ELEVATIONS
The façade strategy aims to further enhance the streamlined proportion of the building and reflect its residential use.
The building’s expression is conceived to establish contextual relationships that recognize the two different character zones surrounding the building: the metropolitan scale of Borough High Street and the finer-grain urban texture of the Liberty of Mint Conservation Area.

09 DETAILED DESIGN & MATERIALS
09.1 QUALITY DESIGN
The development would comprise high quality detailing and materials that strongly enhance the existing building and surrounding context. The contemporary design would contribute to the future character of the area without clashing with the historical character of the area.
09.2 MATERIALS
Proposed facing materials have been carefully chosen to provide a lightweight and contemporary addition that would complement & improve the appearance of the existing building.
The simple material palette will not detract from the strong character of the host building, and will help create a subservient character to the proposed extension.
The materials are all of high quality and are robust enough to provide a long lifespan with minimal maintenance requirements.
