Grade I listed building to open to public

Grosvenor proposes restoring Mayfair heritage landmark, creating a retail, restaurant and community space.

13th November 2015

Grosvenor Britain & Ireland (Grosvenor) has submitted a planning application with Westminster City Council to open the St Mark’s building in North Audley Street to the public on a regular basis. 

Grosvenor proposes a £5m repair and restoration of the former church, letting 14,500 sq ft of space for retail and hospitality while providing a much-needed meeting and event area in the basement for local community groups and charities. The public would be able to visit the building, which has a Grade-I heritage listing, seven days a week.

Grosvenor has consulted with the local community, Westminster City Council, Historic England, The Diocese of London and Victorian Society on the designs, which have been drawn up by conservation architects Donald Insall Associates. Plans include retaining or reinstating all of the building’s heritage features and installing an impressive glass staircase, providing access to the first floor gallery.

Craig McWilliam, Executive Director, London Estate at Grosvenor Britain & Ireland said: “This is an example of Grosvenor taking a long-term approach. We will restore and preserve this beautiful listed building, opening it up to the public seven days a week. Once complete, the restored St Mark’s will further enhance Mayfair’s reputation as a great place to live, work and visit, while providing meeting space for local community groups.”

Lois Pelts, Chair of the Residents’ Society for Mayfair and St James said: “We are delighted that this iconic Mayfair building will be restored and re-opened for the public to enjoy. We support Grosvenor’s plan for retail and restaurant activity plus a new community space at St Marks and look forward to being part of the process to realise this vision.”

The former St Mark’s Church was designed in the Greek revival style by John Peter Gandy-Deering and opened in 1828. It was declared redundant and deconsecrated by the Church of England in 1974. Since 2009 the building has been used as a private events space known as One Mayfair and is in need of substantial repair to secure its long term future. Grosvenor acquired the building last year and, subject to planning consent, aims to commence restoration works in Summer 2016 and to open the doors to the public in late 2017.


The investment in St Mark’s is part of Grosvenor’s long-term transformation of North Mayfair. Nearby in Balderton Street, Grosvenor converted a Grade II-listed carpark into the Beaumont hotel, run by pre-eminent London restaurateurs Chris Corbin and Jeremy King. The Beaumont features ‘ROOM’, an inhabitable sculpture by Sir Antony Gormley. At the rear of St Mark’s, Grosvenor turned the roof above an electricity substation into the award-winning Brown Hart Gardens, a raised 10,000 square feet piazza with a water feature and 50-seater café which opened in 2013.

Grosvenor is also creating a new design-focussed retail identity at Duke Street, complementing nearby Selfridges. Brands recently attracted to Duke Street include Jigsaw's emporium, Penelope Chilvers, E-Tautz, Private White VC and French retailer Ami.
