Successful planning consent for the conversion of Lord Byron's former home, a prominent Mayfair townhouse, to a single-family residence, with basement excavation, roof-level plant room and new terracing.
A landmark Mayfair development comprising 103 hotel rooms and 6 luxury residences, demonstrating CoyEagle's expertise in navigating complex planning environments whilst delivering beautifully resolved architecture.
A refined residential project in the heart of Mayfair — incorporating a club, offices and a swimming pool — where a contemporary stone-framed façade and crafted interiors express CoyEagle's commitment to quality at every scale.
A characterful mews residence on the site of a former dairy in the heart of Highgate Village, designed for its historic Highgate context, where double-height arched glazing brings light deep into the open-plan living spaces.
The conversion of a 1950s reinforced-concrete nuclear bunker into a magnificent family home set in 1.5 acres in Mill Hill. The project contrasts the solidity of the ground-floor original structure — with walls and roof 1.5 metres thick — with a crystalline first floor of floor-to-ceiling perimeter glazing, commanding views across the surrounding countryside.
