A contemporary yet sensitive refurbishment of a Grade II listed Georgian townhouse in Mayfair. The building suffered some insensitive alterations in the 1980 and lay empty for 20 years before Morgan Capital approached us. Fathom’s scheme reinvigorates the building to provide state of the art office accommodation within a heritage setting. The handsomely proportioned front façade will be refurbished, with new windows and insulation, to enhance both the appearance and the environmental performance.

A new lightwell is formed to the rear, bringing light into the basement and providing a courtyard for the offices. Terraces at upper floor levels are conceived as birds’ nests, with finely detailed metalwork and extensive planting, providing private garden spaces for occupiers. Interior materials, joinery and colours bring Georgian elegance into the 21st Century; providing a unique and refined workspace in the heart of Mayfair.

Establishing a respectful relationship with the building’s neighbour to the rear – the Grade II* listed Saudi Embassy – was a key driver, as well as creating a more positive contribution to the Conservation Area. After extensive consultation, Westminster Council have granted planning permission and listed building consent, and work on site is due to start in early 2020.
