For over two and a half decades, Gregory Phillips Architects has been at the forefront of interior design, making residences in Mayfair and its environs truly exceptional, and our commitment to creating beautiful homes has earned us a reputation for excellence. Specialising in a diverse range of residential projects, including contemporary interiors, new-build architecture, renovations, and landscape design, our interior designers in Mayfair consistently deliver award-winning work characterised by sophistication, meticulous planning, and the highest quality craftsmanship. We are passionate about crafting remarkable interiors in the heart of Mayfair and the surrounding areas.
At Gregory Phillips, we firmly believe that a house should be more than just a place to reside; it should be a reflection of one’s individuality and aspirations. With this ethos at the core of our design philosophy, we have successfully partnered with clients to shape their visions into reality. Our design process is grounded in simplicity and revolves around helping our clients envision how they want to live, and then meticulously executing that vision.

Our Presence in Mayfair

Located in the Fitzrovia district of London, in Bedford Row, our offices are strategically positioned, allowing us easy access to projects in the area. Mayfair is not only a hub of timeless elegance but also boasts luxurious shopping destinations, world-class restaurants, and spacious green parks. We are deeply enamoured by this vibrant neighbourhood, and this affection for the area resonates in our work.
Over the years, Gregory Phillips has had the privilege of contributing our expertise to numerous projects in Mayfair and its vicinity. Our portfolio showcases our dedication to enhancing the architectural and interior beauty of the area. Some of our notable projects include the restoration of Listed houses on South Audley Street, as well as the revitalisation of residences around the iconic Grosvenor Square. Additionally, we have undertaken projects within Westminster, including Hyde Park and St. John’s Wood.

Listed Houses on South Audley Street

The preservation of Mayfair’s architectural heritage is a task we hold in high regard. Our work on Listed houses along South Audley Street stands as a testament to our commitment to preserving the historic charm of the neighbourhood while infusing contemporary elements. These projects required a delicate balance between restoration and modernisation, resulting in residences that seamlessly blend old-world charm with modern comforts.

Grosvenor Square Revitalisation



Grosvenor Square, known for its rich history, demanded a design approach that would not only rejuvenate the area but also pay homage to its cultural significance. Our team crafted interiors that evoke a sense of timeless grandeur, while incorporating innovative design elements. The revitalisation of residences around Grosvenor Square has breathed new life into the heart of Mayfair, creating spaces that exude elegance and sophistication.

Beyond Mayfair, our portfolio extends to Westminster, where we have undertaken projects in the picturesque Hyde Park area and the prestigious St. John’s Wood neighbourhood. Each project in these areas reflects the unique character and lifestyle of their respective locales. Whether it’s the serene tranquillity of Hyde Park or the refined elegance of St. John’s Wood, our designs resonate with the essence of these iconic neighbourhoods.

Gregory Phillips’ legacy of creating exceptional interior spaces in Mayfair and surrounding areas continues to flourish. Our unwavering dedication to design excellence, combined with our profound appreciation for the beauty and history of this district, is evident in every project we undertake. As we look to the future, our interior designers in Mayfair remain committed to enhancing the living experiences of our clients and contributing to the enduring allure of Mayfair and its neighbouring areas.
