25 Berkeley Square is a large office building in the north-east corner of Berkeley Square, in Mayfair, with a mix of office, retail, and entertainment uses. Originally constructed in 1906 as a building of luxury mansion apartments. It was converted to office use in 1954.

Forme UK was appointed to provide several enhancements to the building, including creating a new roof extension with attic storeys, remodelling the interiors and designing flexible open plan office space, upgrading to comply with current building regulations, ensuring maximum natural daylight where possible and providing an interior that is fully ambulant disabled and wheelchair accessible.

Our intention was to undertake a sympathetic refurbishment and extension of 25 Berkeley Square to revive the existing building to provide modern, high-quality office with potential for flexible office or retail space at ground floor, that is appropriate for its location at the north end of Berkeley Square.

Externally and internally, alterations have only been made to the non-historic elements and all historic elements of the 1906 Verity building have been retained.
