This project saw the remodelling of almost an entire city block within an historic conservation area in centre London, a short walk from Oxford Circus, The building sits on a prominent corner and is seen from several long views in the area. The transition around the corner is articulated through an expressed pavilion, which floats above the pavement. This is further emphasised by cladding all the structural columns at ground level in mirror. Our proposal seeks to add a strong, calm, yet distinctive ensemble to the frenetic townscape in this part of central London. The project involved the complete reconfiguration and recladding of the entiire building (extension by one storey, lightwell infill, new cores), which is now the Head Quarters of the Engine Group.
