An exceptional example of adaptive re-use, the scheme posited the creation of a first-in-class luxury health and wellness private members club on Mayfair's Berkeley Square.
The site comprises four separate, adjacent and in some cases interconnecting properties on Berkeley Square and Hays Mews - Nos. 49 and 50 Berkeley Square and Nos. 49 and 50 Hays Mews - all Grade II Listed. The brief was incredibly ambitious, challenging the design team to create a new Health & Wellness Private Members Club, to include a new basement excavation under the entirety of the site, including the Georgian Townhouses to the front, and the Mews properties to the rear.
The challenges faced by the design team were complex and overlapping. Firstly, how to sensitively connect four largely disconnected Listed properties, whilst maintaining their unique and separate identities in heritage terms. Secondly, how to create a new basement under the entirety of the site, whilst safeguarding and protecting the heritage fabric above it. Thirdly, how to order and organise a highly complex schedule of accommodation, including swimming pool, treatment rooms, therapy spaces, clinical spaces, restaurant, bars, lounges and private dining rooms. And fourthly, how to enclose under a glazed canopy, the entirety of the rear courtyard spaces. All the time, doing so in such a way as to respect and preserve the Grade II listed existing buildings.
Working closely with the design team, as well as with Westminster’s Conservation Officers, careful party wall breaches were accommodated to seamlessly connect the buildings. With regards to the basement, the team behind the basement excavations at Claridge’s were brought on as specialist consultants, to develop a bespoke ‘mined’ solution. Regarding the glazed canopy, sensitive design detailing and the proposed use of electro-chromic Sage Glass reassured officers that light pollution would be mitigated and any heritage harm avoided. The scheme was approved unanimously at committee.
