Client Grosvenor
Holbein Gardens has been redeveloped with the addition of a two-storey steel-framed extension and a rooftop terrace to the existing four-storey building.
According to the client, the project was committed to circularity and prioritised retention over demolition. This was achieved by retaining the existing concrete frame, while the new areas of the building utilised low embodied carbon materials.
The scheme, one of the first to champion this level of circularity, became Grosvenor’s flagship sustainability project and first net zero development.
The process of designing with and sourcing reclaimed steelwork has demonstrated how reusing steel can be achieved within a standard procurement route.
Approximately 9 tonnes of steel was obtained from other Grosvenor sites in London, with the remaining 16 tonnes procured from reclaimed stock.
