S333 is an award-winning London-based firm with an international reputation for delivering innovative mixed-use buildings and urban environments.

S333 was founded in 1997 in the Netherlands and flourished in an environment that combined experimentation with practical and pragmatic discipline. We continue to find these influences inspirational and they remain a driving force in our approach to all projects.

S333 is led by co-founding partners Dominic Papa and Jonathan Woodroffe. Our commitment to looking as broadly as possible at all the issues, and to consider all the outcomes at all scales, is shared by a multinational team of architects and urban designers.

This approach enables us to see all the constraints, to identify potential in unexpected opportunities and to bring something extra to each project. We are currently working on urban and architectural projects across Europe and Asia.

resolutely international of young practices..."

"The practice's Tarling Regeneration in Shadwell
is a rare and serious piece of urban housing"
