Now in its fourth decade, Gregory Phillips Architects continues to run a London studio designing exceptional private homes, and we’ve carried out a number of projects in Chelsea, including a significant internal refurbishment of a modern house at Henry Moore Court, close to The Boltons, and an apartment refurbishment overlooking Chelsea Harbour.

Much of Chelsea sits within a conservation area, and most projects here need careful navigation of planning requirements, something we handle closely for every client, whatever the scale of the work.

If you’re planning a project in Chelsea, whatever its scale, we’d be glad to talk through what’s involved, particularly if a basement is part of your thinking.

Chelsea Architects

Overlooking Chelsea Harbour, we carried out a full refurbishment of an apartment to an exceptionally high standard: stone floors with underfloor heating throughout, bespoke dark-stained oak cabinetry, marble plaster to the walls, and Lutron-controlled lighting and electric blinds. Every material and system was chosen for both quality and durability, delivered to the standard the location demands.

At Henry Moore Court on Manresa Road, close to The Boltons, we carried out a significant internal refurbishment of a modern house, reworking the interior to suit contemporary family life while respecting the quality of the original build.

Almost the whole of Chelsea falls within a conservation area, and the Royal Borough of Kensington and Chelsea has gone further than most boroughs on basements specifically: since 2016, an Article 4 direction has removed permitted development rights for basement projects borough-wide, and the council’s Local Plan limits new basements to a single storey beneath no more than half the garden. We’re well versed in this policy, and in preparing the impact assessments and construction management plans RBKC expects to see.

We also draw on a long-standing network of contractors, suppliers and consultants who know Chelsea and the standards it demands, and we stay closely involved through construction so nothing is lost between drawing and delivery.

Chelsea has long had a reputation as a centre for design and craftsmanship, from Chelsea Harbour to the world-famous Chelsea Flower Show, a standard we aim to meet on every project we take on here.

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

For Gregory Phillips Architects, interior design is a natural extension of architecture. Their interiors are timeless, elegant, and deeply considered, shaped by light, proportion, and material. Natural textures such as stone and timber are combined with refined detailing to create spaces that are luxurious yet inviting.

Every detail, from bespoke joinery to lighting, is designed to enhance comfort and atmosphere. Whether part of a new build, renovation, or complete home refurbishment, the result is a cohesive, beautifully crafted interior that elevates everyday living.

Our Process

Building or transforming a home is a big undertaking. We start by understanding what matters most to you, so that the house suits both your brief and your site.

We work in seven clear stages, from the first brief to after you have moved in, so you always know where the project is and what comes next. We have taken many complex projects through planning and construction, and we know what it takes to build a house to a high standard.

Most clients work with us from the first design to completion. One of our senior architects leads your project throughout, so you deal with the same experienced person at every stage.
