The Forge, at 105 Sumner Street in central London, is a landmark moment for the platforms approach to design for manufacture and assembly (P-DfMA). Designed for development by Landsec, The Forge is comprised of two new-build commercial office buildings offering tenant spaces in a variety of sizes with in built flexibility. It is built around a publicly accessible internal courtyard, in total comprising c. 19,148m2, with nine storeys above ground and two levels of basement. The development is a high quality and sustainable building which vastly improved the streetscape and public realm as well as providing a premium user experience. In the true spirit of Bryden Wood’s guiding principle of Design to Value the design and delivery centred as many value drivers as possible from environmental sustainability to site safety to cost. As well as achieving BREEAM Excellent and being WELL Gold enabled it is London’s first Net Zero commercial workspace. and is already achieving gains in: - efficiency: a predicted 9.5% reduction in capital cost, 13% reduction in programme, 40% reduction in steel used and 50% reduction in site operatives for superstructure and facade. - sustainability: a forecast 24% reduction in embodied carbon per square metre compared to Business as Usual, a 40% carbon reduction in the substructure and 22% in the superstructure and façade. The Forge is also the first major building completed using the P-DfMA approach, from building design to delivery. In Transforming Infrastructure Performance: Roadmap to 2030, the Infrastructure and Projects Authority has announced that the Government will mandate a platforms approach within two years for social infrastructure. The Platform approach is also the focus of the Construction Innovation Hub. It uses a hybrid steel and concrete structural platform that was developed as part of an Innovate UK First Phase Challenge Fund research project on Automated Construction. The structural platform developed as part of the R&D project will provide the chassis for the office floor space and the project will include the development of cladding and building services components to create a reusable kit-of-parts-based solution for offices. The project showcases the benefits that can be delivered using P-DfMA techniques, Modern Methods of Construction (MMC) and digital technologies on a large-scale new build commercial office development. The scale and ambition of the Forge should be a catalyst for change and a major step forward in proving the new business and financial metrics, whole life performance, and supply chain adoption needed – and deliverable – to accelerate the transformation of the construction sector. The Forge has also won several design and construction industry awards, including the The British Council for Offices - Innovation Award, 2024
