Gregory Phillips Architects has more than 30 years of experience as a London architectural studio, designing exceptional private homes, with a strong and established portfolio of projects across Hampstead, Hampstead Garden Suburb and the surrounding conservation areas.
Our work spans Hampstead’s most sought-after streets, including a complete remodelling with basement on Frognal, and projects on Frognal Lane, Reddington Road, Downshire Hill, Mackeson Road and Upper Terrace, as well as an almost entirely subterranean house on Spaniard’s End.
If you’re planning a project in Hampstead or Hampstead Garden Suburb, we’d be glad to talk through what’s involved, we know Camden’s conservation department well, and understand the additional layer of consent required from the Hampstead Garden Suburb Trust for properties within the Suburb itself.
Architects in Hampstead
Hampstead has been one of London’s most desirable addresses for over a century, prized for its village character, literary history and proximity to Hampstead Heath. Its streets are lined with substantial Victorian and Edwardian houses, many within conservation areas, which makes considered, sensitive design essential to almost every project here.
We’ve built a substantial portfolio of work across Hampstead’s most desirable streets, including the complete remodelling of a large house on Frognal, with a new basement and full house refurbishment, alongside projects on Frognal Lane, Reddington Road, Downshire Hill, Mackeson Road, Rosecroft Avenue, Arkwright Road and Upper Terrace. On Spaniard’s End, we designed an almost entirely subterranean house, a distinctive response to a site where the visible footprint needed to stay minimal.
One of our largest projects in the area involved a 12,000 sq. ft house with a new 3,000 sq. ft basement beneath the existing building, alongside a full refurbishment of the residence, interior design and landscape design throughout, finished with marble, stone, timber and leather detailing.
Hampstead falls within the London Borough of Camden, and we know its conservation and planning department well, having worked on numerous listed and conservation-area properties across the borough. Hampstead Garden Suburb is a different matter altogether: administered by the London Borough of Barnet, it also falls under the separate Hampstead Garden Suburb Trust’s own Scheme of Management, meaning many projects need approval from both the council and the Trust before work can begin. We’re familiar with navigating both processes together.
Delivering a project to the standard Hampstead demands isn’t just about design, it depends on knowing which contractors can actually execute it. Only a small number of London contractors consistently work to this level of quality and precision, and we’ve built long-standing relationships with them across numerous projects in the area. We stay closely involved through construction so nothing is lost between the drawings and the finished home.
Whether it’s a family house on one of Hampstead’s period streets or a property within Hampstead Garden Suburb’s protected setting, we’d be glad to discuss what’s possible for your home.
In Hampstead, our studio offers the full range of architectural services, with involvement from concept design and planning consents through to construction information and house styling.
