Office revamp

Striking high gloss Proteus HR soffit panels and rainscreen cladding have been used on a futuristic Grade A office redevelopment next to Heathrow airport, London


Striking high gloss Proteus HR soffit panels and rainscreen cladding have been used on a futuristic Grade A office redevelopment next to Heathrow airport, London. The original 4 Longwalk in Stockley Park was designed by Arup Associates and completed in the early 1990s. Barr Gazetas architects were commissioned to carry out an extensive refurbishment, including fitting the building out to CAT A standard and achieved an EPC A and BREEAM Excellent, with the works completed by Kier Construction.

The makeover has remained faithful to the original Arupdesigned building, with a new dynamic entrance, atrium and dramatic roof soffit featuring Proteus HR high gloss panels in RAL 7004 Signal Grey. Identical Proteus HR high gloss panels were used at the rear of the building to create a vertical band of rainscreen cladding that runs up the building over a stair core and ground level entrance and walkway.

The design team at Proteus Facades worked with Deepdale Solutions, the cladding and soffit installer, to create an engineered solution on this challenging project, with visual purity of the soffit and rainscreen cladding being the overall architectural requirement.
