London’s High Court has given permission for a judicial review of the plans that were approved by Westminster City Council last year.
Antiques dealer Humphrey Carrasco and interior design firm Coote Bernardi are among those galleries affected.
Property company Grosvenor plans to redevelop Newson’s Timber Yard on the Pimlico Road which is owned by builders’ merchant Travis Perkins.
Travis Perkins applied for the judicial review to challenge the legality of the planning decision and the review was granted on March 27.
Travis Perkins’ group property director Martin Meech, said: “So far in this case, Grosvenor and Westminster City Council have expressed a disappointingly dismissive attitude towards the views of local residents and businesses. Travis Perkins want to make it very clear to colleagues at the timber yard and to the community in Belgravia that this issue has not reached its conclusion.”
A Grosvenor spokesman said: "As an interested party, we are ready to assist the review in any way required."
Grosvenor’s plans include the creation of two larger and two smaller shops from the existing five galleries and shops as well as the reconfiguration of five existing flats into seven rental apartments.
Grosvenor announced initial plans to remodel the site in June 2015 but it faced months of objections from local businesses and a protest group was formed called Save Newson’s Timber Yard.
It then altered its plans and received permission in October 2016.
Grosvenor has been attracting interior design specialists to the area and recently signed furniture and lighting designer Cox London on Ebury Street, Robert Kime and Sibyl Colefax & John Fowler.
