For more than three decades, Gregory Phillips Architects has run a London studio designing exceptional private homes, with a portfolio of work around Hyde Park that spans listed building refurbishment, mews house reconstruction and high-end interior design.

On Stanhope Place, part of the historic Tyburnia development, we carried out the refurbishment of a Grade II listed building including a new basement. In Hyde Park Mews, we completed the careful reconstruction of a house, also with a new basement level. On the edge of the park in Knightsbridge, we completed a full interior fit-out for a mansion-block apartment, recommended to the client by a prestigious Parisian furniture designer, the brief included a humidor built into the living room joinery and a window seat that rises on an automated pneumatic system for a better view. See our Knightsbridge project here.

This part of London sits within the City of Westminster, and we’ve built a strong track record working with the council’s planning and conservation teams on listed buildings and basement developments alike, we’d be glad to discuss what’s possible for your property.

Architects in Hyde Park

Much of the area around Hyde Park falls within the City of Westminster, and a significant amount of it sits within conservation areas or involves listed buildings, Stanhope Place, where we refurbished a Grade II listed house from the Tyburnia development, is a case in point. Basement development is common here too, and we added a new basement level as part of that project, working closely with Westminster’s conservation officers throughout.

Elsewhere, in Hyde Park Mews, we carried out the careful reconstruction of a house to include a new basement, and on the edge of the park in Knightsbridge, we completed a full interior fit-out for a mansion-block apartment after being recommended to the client by a prestigious Parisian furniture designer. Every detail was designed to work with the client’s own furniture, from a humidor built into bespoke joinery to a window seat that rises on an automated pneumatic system, so it can be enjoyed sitting or lying down. See our Knightsbridge project here.

Projects in this part of London tend to demand the highest standard of execution, given the exclusivity of the area, and that’s as true of the trades and suppliers involved as it is of the design. We work with a small number of trusted contractors and consultants who we know can deliver to that standard, and we stay closely involved through construction to protect the quality of the finished result.

If you’re planning a refurbishment, basement addition or interior design project around Hyde Park, we’d welcome the chance to talk it through.

In Hyde Park, our studio offers the full range of architectural services, with involvement from concept design and planning consents through to construction information and house styling.

Our Process

Working on a home with an architect is a personal journey, often spanning several years. We take time to understand our clients’ needs and priorities, ensuring each house responds thoughtfully to its brief and site.

The studio has a long record of delivering complex and demanding projects, navigating planning requirements and construction to the highest standards.

While our approach is flexible, most of our projects involve the studio from concept to completion. Our experienced team of project architects, many of whom have worked with the studio for years, ensures continuity, technical excellence, and careful attention to every detail.
