Completed in Autumn 2020, 25 Berkeley Square creates an additional 47,000 sqft of office and retail space in the heart of Mayfair.


Originally designed by Forme UK, Atomik were appointed on behalf of the contractor, Synergy Properties Ltd, to provide contractor’s proposals under a traditional contract which included a number of CDP elements.


Our role has involved the coordination of sub-contractor packages and issuing these as contractor’s proposals to the client design team.


Packages of work consisted of the coordination of the new external stone wall extension, two storey, mansard roof, new shopfronts at ground floor level and service yard. In addition, our scope also included the detailing and coordination of the ornate leadwork, the external decorative panels, the internal fire stair package and the external glazing. On several of these elements, packages were provided for the approval of planning conditions.


Project management included, but were not limited to, design workshops, onsite reviews, and weekly design meetings.


This successful collaboration with the contractor and design team has resulted in a distinguished and elegant outcome.
