LCW summit house

UK-based construction firm Willmott Dixon has won a £20m contract from Low Carbon Workplace (LCW) to upgrade Summit House at Wilson Street into a 9,500m², low-carbon, cat-A office space.

The project is the firm’s fourth from LCW, a consortium formed by Stanhope, Threadneedle and The Carbon Trust that specialises in transforming old London offices into energy-efficient workplaces.

Under the new contract, Willmot Dixon will be responsible for making key changes to the 1980s-built construction, which will include replacing an existing storey with two new ones, to create a modern office set-up over six levels.

"This is a defining moment that points to a steady rise in property owners investing to create low-carbon office environments in London."

According to Willmot Dixon, the offices will feature a new copper-glass façade, and modernisation work is likely to be completed by next August.

Strategic location of the development near Old Street’s Silicon Roundabout is expected to attract start-ups to the centre, following the upgrade.

Willmott Dixon North London manager Chris Tredget said: "This is a defining moment that points to a steady rise in property owners investing to create low-carbon office environments in London, driven by tenant demand and the upside in value.
