Gregory Phillips Architects has spent more than 30 years designing multi-award-winning contemporary residential architecture, with work in Knightsbridge that includes a full interior renovation of a mansion-block apartment.

We were recommended to the client by a prestigious Parisian furniture designer, and the project was designed from the outset to work in harmony with the client’s existing furniture, down to a humidor built into the living room joinery and a window seat that rises on an automated pneumatic system for a better view.

Knightsbridge’s Georgian, Victorian and Edwardian buildings sit mainly within the Royal Borough of Kensington and Chelsea, bordering the City of Westminster, and mansion-block projects often bring their own management and consent requirements alongside council planning, we’d be glad to talk through what applies to your property.

Architects in Knightsbridge

Knightsbridge’s mansion blocks and grand townhouses call for a different kind of care to a standalone house, leaseholder and management company consents often run alongside the usual planning process, and mansion-block projects need a design team that understands both.

In one mansion-block apartment, we were recommended to the client by a prestigious Parisian furniture designer to create an interior that would work in harmony with their existing pieces. Every detail was designed around that brief, from a humidor integrated into bespoke joinery to a window seat that rises on an automated pneumatic system, so it can be enjoyed from both a sitting and lying position. Luxurious stone was used throughout the bathrooms, carefully lit to create an understated, sophisticated feel. See our Knightsbridge project here.

Getting the logistics right mattered as much as the design on this project, coordinating the delivery of the client’s furniture into the building alongside the construction programme required careful planning from the earliest stages.

Whether your project in Knightsbridge is a full interior scheme or a wider renovation, we bring the same close attention to detail and the same trusted network of joiners, stone specialists and consultants that shaped this project.

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