Over the years, it has been home to many famous Dukes and Earls and now almost three centuries later, has been restored to create some of the finest apartments in London once more.
Major works were required to sufficiently extend the existing Harcourt House, involving the refurbishment and structural alterations for the Grade II listed building to convert the existing units into high-end residences.
The overall refurbishment of the building gave the opportunity to restore, repair and clean the stonework of the façade and replace the windows with new, thermally efficient conservation windows matching the original design.
A basement excavation allowed for the formation of additional floor under the existing single floor below the ground floor with underpinning. Above ground, the existing sloped roof on the rear façade was removed and replaced, alongside the the creation of two new penthouses at roof level.
The original building design for Harcourt House provided for 4 apartments per floor with two separate and symmetrical cores; the redevelopment retains this principle exactly.
The original plan provided high ceilings to the front ‘grand rooms’ – inserting two additional floors to the rear bedroom wings where lower ceiling heights are acceptable. Again this principle has been retained.
The interior design features of the apartments included the restoration of the original decorative mouldings, door designs and other features to a very high standard. In particular the Grand Rooms have been fully restored with excellent light and views into Cavendish Square.
The residential accommodation provides a mix of 25 apartments (1, 2, 3 and 4 bed), arranged either as duplex or lateral units.
Other facilities include a full gymnasium and spa with changing rooms, sauna, steam room, treatment areas and studio. The scheme is also a car-free development that provides a total of 64 cycle parking spaces.
