Architectural Services

Each project Gregory Phillips takes on is a chance to create something unique and spectacular, taking the client’s vision of their dream home from plan to reality. We ensure homes look, flow and feel exactly as they imagined—achieved by our exceptional level of architectural services and attention to detail.

We subdivide our architectural services into foundational and other services, such as sustainable design and site selection. In addition, GPA offers design services unique to each project, whether newbuild architecture, remodelling, or concept and landscape design. 

We carefully manage issues of feasibility, procurement and planning permission from the outset, allowing our clients to relax and enjoy watching their dream home take shape from start to finish. 

Gregory Phillips Architects offer a holistic service, combining high-end building design with interior and landscape design. We manage each construction stage in-house—always utilising open spaces and maximising light—and work closely with a network of skilled craftsmen and specialists.

Some of our completed projects have been honoured with the highest accolades. These include prestigious Royal Institute of British Architects awards and nominations for the ‘House of the Year’ competition, ‘Best Individual House in the UK’ and ‘The Best House in Europe’.

Scope of work

In collaboration with the client, we determine the scope of work to be designed—the research and development stage. We will ask questions to gain an understanding of your design aspirations and any problems that may arise. 

Design development

Next, through a series of sketches, formal drawings and computer-aided designs (CAD), GPA develops the floor and site plans and building elevations for a complete design of the building. The process encompasses structural and mechanical considerations, as well as HVAC, plumbing and electrical decisions.

We will always aim for a cohesive scheme that ensures a seamless experience from concept design to the finished home.

Gregory Phillips Architects take care of every aspect of your project, making best use of the square feet available to provide a floor plan to suit your needs. View our Work with us page for more information.

Architectural Design Services

Gregory Phillips’ design teams tailor building projects to the way the clients live. We draw upon an established and trusted network of talented craftsmen and suppliers to create exquisite homes. 

Each interior design project, from inception to completion, incorporates concept design, CAD drawings, specifications for construction, lighting design, project management, bespoke furniture design and selection.

New Houses

While considering the specific location of each project, GPA creates tailored new houses to match the client’s individual lifestyle. Whether a compact urban site or rural landscape with extensive views, the goal is to maximise the potential of the site and deliver a modern home with exceptional living space.

In all new-house design projects, GPA determines what materials best reflect the location and aesthetic. And it’s not just exterior considerations. We are often engaged to carry out the interior design and build and select furniture and soft furnishings. 


GPA’s architectural services extend to projects that involve the remodelling and extending of existing houses. Remodelling projects may involve re-organising historic and existing buildings to create luxury homes suitable for today’s lifestyles and ways of living.

Clients may require remodelling services such as basement or loft conversions or space renovations to accommodate swimming pools, leisure areas, gyms and bedroom suites.

When carrying out projects involving listed buildings, we’re always sensitive to the historic aspects of houses whilst adding contemporary elements. 

Concept Design

Although often included as part of a holistic service, Gregory Phillips also offers concept design as a standalone architectural service. The reason for this is that the client may require additional flexibility between the separate design and construction stages.

However, we will also develop initial concept designs before providing architectural and interior design services for the project from inception to completion of the construction.


Gregory Phillips Architects extend their modern house services to projects outside of the UK.

Typically, the local team to the location obtain the site information, deal with obtaining planning consent and permits, and organise the construction.

We collaborate with the client and local team to create a contemporary house that provides the modern home desired.

Interior Design

It’s critical that our structural engineers understand the client’s vision to create interiors that exceed their expectations and create luxurious yet practical spaces using a range of materials, such as timber, stone, marble, leather, metal, concrete and glass. 

Our interior design services extend to bespoke cabinetry and furniture for bathrooms or kitchens. We’ll also help the client select soft furnishings and styling to the rooms with rugs, blinds, curtains, linen, art work and objects to make the house a home.

Integration of state-of-the-art audio-visual systems, security and lighting controls can also be part of the interior design service. 

Gregory Phillips Architects is a boutique London-based architecture and interior design practice, specialising in contemporary luxury homes.
