Iacopo Sassi, Director

Iacopo has worked both nationally and internationally on a variety of projects with a focus on luxury residential refurbishments, extensions and new build projects in the Greater London area. 

With more than a decade of experience he has worked with offices that implement a high standard of design such as Foster+Partners, Stanton Williams and Barbara Weiss Architects. Working with mostly small to medium sized projects he gained an interest into architectural details that he considers essential for the success of a project. He believes that the quality of a project can be measured in terms of space, materiality and light.

Originally from Italy, Iacopo is a third generation designer who has always been interested in history, art and architecture. Iacopo is a member of both the ARB and RIBA. He currently resides in Hampton and serves as Deputy Chair and a Planning Advisor for The Hampton Society.
