NCA has undertaken the complete rebuild of six luxury apartments whilst retaining the existing facade of a large Victorian terraced house in the Mayfair Grosvenor Estate. The core of the project is a new sweeping staircase in Pietra Serena sandstone, polished stainless steel balustrade and walnut handrail, plus the integration of a new lift. Each apartment is carefully designed to a high specification with black oak flooring, kitchen and doors, leather panelling and bespoke furniture in pale ash. The red brick and terracotta facades are restored to their original states.
