Completed Project

Penthouse refurbishment — Carlton Lodge, Belgravia SW1X

Penthouse duplex transformation in a Grade II listed building envelope with roof reconstruction, structural steel and premium apartment fit-out.

Carlton Lodge Belgravia penthouse refurbishment

The existing case-study record covers a high-spec penthouse duplex and adjacent apartment refurbishment programme in a listed Belgravia context.

Roof reconstruction and apartment fit-out

The most significant intervention was a complete roof reconstruction using structural steel to create the headroom and spatial quality expected at this price point. New steel portal frames were craned into position during carefully coordinated weekend lifts, with the existing roof structure stripped back to facilitate the new geometry while maintaining the external roofline profile required by the listing.

The interior design programme demanded the highest specification throughout: engineered oak flooring, natural stone bathrooms, bespoke kitchen cabinetry with integrated Gaggenau appliances, and a full smart home system. Every material selection was made to reflect the Belgravia standard while delivering contemporary living for the international buyer market.
