Stamisol Safe One supports modernisation of civic landmark in West London
As part of the ambitious redevelopment of the historic Hammersmith Town Hall in London, Stamisol Safe One breather membrane was specified to provide a high-performance solution for the external building envelope. The Grade II-listed landmark is being refurbished and extended as part of the wider Hammersmith Civic Campus masterplan.
The £155 million project is being delivered through a joint venture between Hammersmith & Fulham Council and A2Dominion, with construction led by Ardmore. The scheme includes over 15,000 sqm of state-of-the-art office and public space, 204 new homes and more than 10,000 sqm of commercial premises, all designed by Rogers Stirk Harbour + Partners.
A striking feature of the development is a contemporary three-storey ‘glass box’ extension, suspended on 15-metre-high stilts above the original Town Hall. Constructed using 1,300 tonnes of structural steel, this additional 4,500 sqm of internal space also includes a new glazed lift and link bridges within the enclosed courtyard. The Civic Campus is designed to be one of the most inclusive and environmentally forward-thinking civic buildings in the UK.
