Following the success of 40 Eastbourne Terrace, Land Securities appointed the practice to renovate a group of adjacent buildings of the same 1960s vintage. The existing18-storey office tower and two lower wings are highly visible from the neighbouring conservation area. A number of cladding solutions were reviewed, including a terracotta screen to shade the areas in direct sunlight. A glazed solution was developed with silk-screened fritting to protect against solar gain and to reduce overlooking, following consultations with residential neighbours.
The external cladding is conceived as a glass veil draped over the existing structural frame with a subtle opaque pattern to vary the transparency of the façade. This avoids a challenge experienced at number 40, of installing cladding between existing and varying structural bays.
