• Westmark Tower – Costs Cut On Curtain Wall

The 110m, 29-storey curved Westmark Tower features more than 14,000sq.m of clever cost-cutting unitised curtain wall designed and supplied by AluK and installed by envelope contractors Martifer.

The building is part of Berkeley Homes Central London’s West End Gate development in Marylebone. It was the tallest residential tower completed in central London during 2021.

AluK worked with the lead architect Squire & Partners, delivery architect Design Delivery Unit (DDU), façade consultants Cladtech Associates and structural engineers WSP on a RIBA 4 system design for the unitised envelope.

 “We created a unitised façade solution for the post-tensioned concrete frame while making sensible savings on metal and accessory costs.”

– Steven Watkins 

Head of projects, AluK

Time saving

“As well as accelerating the design of the structural frame, this approach saved Berkeley many months compared to the normal procurement route,” continues AluK’s  Watkins. “And meant that the tender returns for the fabrication and installation of the façade were accurate and comparable. It saved the tenderers the normal costs associated with a bid and ensured that all the commercial and design iteration took place pre-bid and was not left to interpretation.”

Configuration

The final unitised solution features more than 2,200 unitised cells of three principal configurations. Each floor comprises a vision cell, typically housing AluK’s concealed vent and full height glass panes; a panel cell, specifically designed to house specialist internal  framework to carry articulated glass reinforced concrete, feature piers and spandrels; and a recessed balcony cell with an integrated floating glass balustrade.
