55-56 Chamber Street is a development project by Marldon in London to create new office and hotel accommodation. The project is situated between a new development (31-33 Prescot Street and 99 Mansell Street) and the existing De Mazenod House at 62 Chamber Street, and currently comprises a disused railway siding and arch (site shown above). The proposal is to demolish the railway siding and arch and to construct a new 11 storey building, with basement, to create the new mixed space. Since 1968 Marldon has been building a reputation for expertise and excellence in the London property market and have established themselves as leading design and build specialists, providing residential and commercial developments, sales, lettings and serviced apartments.
ADW were commissioned by Marldon to provide carbon accounting and life cycle costing services for the project, which is seeking to achieve BREEAM Outstanding certification. ADW provided carbon footprint (LCA) report and advice for the proposed office and hotel. Elements considered included substructure, frame, all floors, roofs, stairs and ramps, external walls and windows, and roads, paths and paving. ADW also carried out a life cycle costing analysis over a 60 year period which included estimates for initial construction, major replacements, maintenance and operation for the proposed office and hotel.
