About LEEP Architects.

LEEP Architects, led by Marcus Lee, is a London-based architectural practice renowned for its collaborative approach and diverse portfolio spanning civic to ecological projects. With a focus on innovative houses, master-planning, and award-winning designs, the practice has made a mark in the industry through its work on private homes situated in prestigious locations like Mayfair and Chelsea, as well as international projects​​.

Marcus Lee, the force behind LEEP, has a rich history in architecture, having held key roles at the Richard Rogers Partnership where he contributed to iconic designs including Lloyd’s of London and Heathrow Terminal 5. After founding his own practice, FLACQ, and a stint as UK Director of Nordic Office of Architecture, Marcus reformed LEEP in 2021, bringing his extensive experience and innovative vision to the firm​​.

LEEP's portfolio showcases a range of projects that demonstrate the firm's capability to work across different scales and contexts. Notable projects include the Framehouse, a detached five-bedroom eco-home in East London, which received a RIBA award for architectural excellence. This project exemplifies LEEP’s ability to create unique designs on challenging sites​​. Other projects, such as the Lochdon Holiday Chalet, Four Outbuildings, and Orleston Mews, further illustrate the practice's versatility and commitment to pushing the boundaries of design​​.

The practice’s ethos is rooted in creating designs that respond thoughtfully to their environment and clients' needs, with an emphasis on sustainability and innovation. This approach is evident in projects like the Porto Masterplan and the Bankside Kiosk, showcasing LEEP's engagement with both large-scale urban planning and smaller, playful installations​​​​.
