An unloved, almost derelict Grade II listed building in Victoria was transformed into a market leading office building. Coupled with the addition of residential to the mews at the rear of the building, this project has been a great success story for our client. The building had been insensitively altered in the 1970s with the original stair having been removed from no 48, many steels inserted, roofs replaced with plant rooms and much original fabric removed. We were tasked with upgrading the building to meet modern standards. This meant the removal of the single lift and 1970s rambling staircase. These were replaced with a new twin lift core, new rationalized stair core and modern elegant toilet facilities. The entrance to the commercial space was rationalized with both 46 and 48 leading into a common reception. An unused, dirty light well between the commercial building and residential mews to the rear was covered with a striking glass roof to create additional usable internal space and bring quality light into the floors.
