This refurbishment project increases the residential accommodation in an existing 1960s building in London’s Fitzrovia. Ten new apartments are created by extending the building with a new full-height block to the rear and replacing an existing penthouse level with a new structure. Each apartment features a projecting glazed pod which offers views out over the city and provides a sense of connection with the weather and the changing seasons. The existing building presents two very different aspects to the surrounding area, with formal facades confronting Weymouth Street and a far more eclectic and utilitarian elevation facing Bridford Mews at the rear. In response to these contrasting conditions, the design proposes a highly modelled, brass-clad elevation at the rear of the building, which will greatly enhance the appearance and potential of this fascinating pocket of urban space. By contrast, the Weymouth Street elevation features a discreet stepped addition to the existing structure which is set back and clad in a darker alloy of the same brass. The development incorporates a range of renewable technologies, including ground source heating and cooling and a green roof.
