50 Stratton Street and 50 Berkeley Street

Welcome

Welcome to the virtual exhibition of Astrea’s proposals to sensitively upgrade and refurbish two separate buildings at 50 Stratton Street and 50 Berkeley Street.

Proposed view of 50 Berkeley Street

We hoped to be able to show you our proposals for the site at a public event but unfortunately due to the ongoing Coronavirus situation, this is not possible at the moment given both government advice and our commitment to community wellbeing.

As a result, this consultation is taking place ‘at-a- distance’ – using a range of different feedback tools. We are committed to engaging widely and making sure everyone has an opportunity to have a say on the plans in a way that suits them.

You can provide your feedback on the information set out in these boards by clicking on the ‘Feedback Form’ on the ‘Have Your Say’ section on our website. You can also provide your feedback via post.

We are keen to understand the views of our neighbours and the local community before submitting a planning application to Westminster City Council.

Kanda The Site

Site history

The site was originally part of the Gardens of Devonshire House, ALBEMARIE ST a grand London Mansion built in 1673 by John Berkeley (Baron Berkeley of Stratton) which continued up to Berkeley Square. The original Devonshire House was abandoned in the early Twentieth DOVER ST century and subsequently replaced by the modern-day commercial building of Devonshire House to the south.

BERKELEY ST In 1926, the site of 50 Berkeley Street was first developed along with The Mayfair Hotel to the North, and the modern-day Lansdowne House. 50 Berkeley Street was built as an office building, but also housed car showrooms and was the Headquarters of the travel 50 BERKELEY STREET agent Thomas Cook, whilst 50 Stratton Street was redeveloped in the 1930s. 50 Berkeley Street was further extended in the 1950s, adding further floors and a new roof to the building.

50 Stratton Street was subsequently demolished and the current 50 STRATTON STREET office building was constructed in the late 1990s. At that time 50 CURZON ST BOLTON ST Berkeley Street underwent a substantial modernisation, with further STRATTON ST PICCADILY expansion to the upper floors.

The site today

Today, the site is a diverse mix of office and retail usage.

Central London Plan showing site location The buildings form a whole city block, defined by Berkeley Street to the East, Stratton Street to the West and North, and Mayfair Place to the South.

Whilst they are separate buildings, 50 Berkeley Street and 50 Stratton Street share a lightwell. Neither building is listed, and the neighbouring properties Devonshire House and no. 6 and no. 8 Stratton Street are Grade II Listed.

The buildings are within the Mayfair Conservation Area and the area of the adopted Mayfair Neighbourhood Plan.

There are a number of issues with the existing buildings which we are keen to address:

We are keen to work with Westminster City Council to improve the public realm and introduce more urban greening, enhance the setting, and improve the relationship of the building to the surrounding area.

Public Realm

The existing public realm around the site is unwelcoming and in need of investment. It currently has the character of a service or cut-through road due to the vehicular pick and drop-off, and a lack of urban greening.

Our proposals aim to enhance the public realm around the site. To Stratton Street and Mayfair Place, the proposals seek to create a better quality street scape. In front of 50 Berkeley Street, a wider pavement could create more generous public circulation. The proposals could also integrate with the proposed connection to Curzon Street through the Berkeley Arcade / Nightingale House development in due course.

As part of our long-term vision for the area, there are a series of more fundamental public realm changes that we intend to discuss further down the line with Westminster City Council and neighbouring landowners that would seek to make improvements to Berkeley Street, Stratton Street and Mayfair Place.

The focus of the enhancements would be in-line with the criteria outlined in the Mayfair Neighbourhood Plan, notably:

• Creating additional space for pedestrians • Creating Attractive Streetscapes • Multifunctional Streetscapes • Accessible and safe Streetscape • Improved pedestrian experience

Public Artwork

The current building at 50 Stratton Street incorporates public realm artwork from the early 2000s by Norman Ackroyd R.A. C.B.E.. The artwork is etched stainless steel panels set into the first-floor balustrade. As the artwork nears 20 years of age, the condition has deteriorated and due to its location on the building and the artwork is hard to see from the street level.

We are committed to investing in new high-quality artwork, adding to the overall townscape. We would also look to restore the current artwork and placing it within the building where it will be better protected. Servicing

We recognise the importance of local amenity, therefore we will Proposed Ground Floor be submitting a Delivery & Servicing Management Plan which will Berkeley Street Office waste stored reduce the effects of servicing on neighbouring properties and other and collected in same road users. location as existing, with a basement and ground floor store, 50 Berkeley Street featuring a platform lift between the two stores Servicing at the existing 50 Berkeley Street site is undertaken separately between retail and office uses, with retail units receiving deliveries directly to their unit, either through the main entrance Existing servicing and Existing servicing on Stratton Street or via servicing access to the rear of the unit waste strategies for entrance via the north ground floor (and core lift to be retained on Mayfair Place for the existing restaurant unit.

We are committed to the refurbishment being an exemplar of sustainability, delivering an energy-efficient building which is future- proofed with additional greening and which has the wellness of its tenants at heart by offering improved natural light and new terraces.

Circular Economy

The proposed scheme will follow circular economy principles to Raw materials retain and reuse existing materials and minimise waste to landfill. The proposed scheme involves the refurbishment of an existing building, contributing to the preservation of materials and resources, which is one of the main principles of Circular Economy.

Plant and management and Waste prevention The majority of existing building’s services, plant and equipment will be replaced as part of the refurbishment works. The proposals will Resource Production see the introduction of highly efficient plant that contributes towards Efficiency the carbon emissions targets of the proposed scheme and better serves the needs of a high-quality office space.

Energy Strategy E co- innovation The proposed energy strategy, which has been developed as an all-electric solution, will reduce CO2 emissions to meet the net zero carbon target, by implementing a combination of energy efficiency and low and zero carbon technologies.

Renewable Energy

The proposed scheme will utilise air source heat pumps to provide Consumption heating and cooling. The heating component of the air source heat pumps is considered renewable energy technology. Next Steps

Thank you for taking the time to look through our early plans for the extension and refurbishment of 50 Stratton Street and 50 Berkeley Street.

We hope you found this virtual exhibition informative and useful.

We would appreciate it if you could fill in our feedback form, either online or by ost.p Your Proposed view of 50 Berkeley Street thoughts and feedback will be very helpful as we develop more detailed plans over the next few months.

Once the consultation period ends, we will take the time to review your feedback ahead of a planning submission to Westminster City Council.

In the meantime, we are keen to speak to as many people as possible in the local area. If you have any questions, or would like to organise a more detailed presentation on these plans, please do get in touch with the project team on the details below:
