One Amercia Square, London

The design of One America, an office development over Fenchurch Street Station integrates a £14m bespoke unitised curtain wall system.

The design of the system utilises 40mm thick, high specification, durable Brazilian granite on steel trays integrated with glass and aluminium curtain wall hung on 12m wide structural steel trusses off the primary structural columns.

The complexity of the design demanded facade engineering specialists collaborating with the design team in order to design support systems for the granite and integrate the off-site construction process to the programme.

The thermal massing qualities of the granite also contributes to the internal office conditions controlling heat gain and loss, light levels and acoustic vibration.
