Keystone were one of a few selected specialist trades credited with the stunning transformation of this 5 floor private residence in Belgravia. We supplied and installed cut to size honed Volakas marble slabs to walls and floors to various bath and shower rooms. Tumbled Carrara and Nero Marquina tiles were used in a chequerboard pattern to the front lightwell and rear courtyard. We fabricated and installed Nero Assoluto granite treads and risers to form a new staircase at the rear of the property, and precast copings to the roof parapet. Several bespoke architectural features were prominent, including worktops, vanity tops and fireplaces. Italian porcelain tiles were installed throughout the lower two floors of the property, including basement staircase and pool surround. We also installed tiles to the mechanically lifted pool floor, which in the fully raised position is also used as part of the gym. Photo credit - Keystone Restoration Ltd
