New office development, featuring floor-to-ceiling glazing, aluminium shading fins, and roof gardens that offer views out onto Queen Elizabeth Olympic Park.

BREEAM Excellent 

14 Westfield Avenue is a new 800,000 square-foot commercial office development in Westfield’s Stratford City estate.

Eckersley O’Callaghan has engineered the facade of the building, which is formed of two blocks standing at 13 and 14 storeys tall. They are wrapped in floor-to-ceiling glazing, over-clad with an external grid of shading fins.

We have engineered the fins to be made from bronze-anodised aluminium in order to provide a substantial reduction in solar gain, allowing greater clarity in the glass and contributing to a BREEAM Excellent certification and a highly energy-efficient building.

The building also features a roof garden enclosed in a glazed ‘crown’, a seven-metre-high glazed lobby, and a glazed roof over two central atriums.

We have worked closely with the architect and fabricators to develop a bespoke unitised curtain wall system for the external facades. The large scale of the external shading fins has required extensive pre-engineering of the system and up-front design of the bespoke aluminium profiles. Construction is underway and due to complete in 2019.
