De Rosee Sa are an award winning, design-led architectural and interior design practice located in London. We have developed a strong reputation for designing contextual, beautifully crafted, and well-considered architecture and interiors.


Whether designing a residential property in London, a dining hall for an infant school or a woodland cabin, at De Rosee Sa, our unique and collaborative design approach allows us to develop each project on an individual basis rather than having a set style. 


Our buildings provide elegant and creative solutions to meet the practical and budgetary needs of a project whilst also maximising value for our clients.

Since 2007, our architecture firm in London has provided smart and imaginative designs to the residential, educational, retail and community sectors.


We are committed to bringing you a full scope of architectural services, from the initial concept stage all the way through the completion of the project.


What sets us apart from other firms is how we value our clients’ interest. We take the time to understand what our clients want and wish to achieve. This way, we come up with designs that fully capture the clients’ vision while adding financial and lifestyle value.
