Quadrant 4 transforms a 1930s Art Deco Hotel Building off Piccadilly Circus into 48 luxury apartments. The scheme includes the renovation of the existing street facing façades and remodelling of the top seven floors of the nine-storey building.

The 5th, 6th and 7th floors are constructed using traditional glazed terracotta as a rainscreen type cladding attached to a precast concrete inner leaf that provided the waterproof line.

The complex design included over 4,000 individual terracotta units supported and restrained with a jointing arrangement to mimic the original construction details.

The glaze colour was carefully reviewed and a tone 15% lighter than the original was used to lessen the visual impact of the new upper levels.

To overcome the challenge that the reduced thickness of the flank elevation posed, tiles cut to the same coursing height as the faience were glazed to match the new terracotta units and bonded to the newly rendered substrate that had been carefully cured during the preceding works.

The retained facades were cleaned and repaired to remove decades of neglect and damage.
