Founded in 1997, and with offices in London and Amsterdam, S333 is an architectural and urban design practice with an international perspective and global reach.


Our approach is based on integrated, joined-up thinking, working seamlessly across the different scales of architecture, masterplanning and place making – strategy and detail.


We look as broadly as possible at all the issues, to consider all outcomes, at all scales. This offers unexpected opportunities; delivering more valuable solutions for our clients that bring something extra to each project



Dominic Papa and Jonathan Woodroffe are actively involved in all stages of the design process. 


They studied Architecture together at the University of Portsmouth before Dominic moved to the Architectural Association to complete his studies while Jonathan continued his studies at the University of Cincinnati, USA.


Dominic and Jonathan champion design quality in many forums across London and Europe and have contributed their knowledge to design guides, handbooks, peer review and as independent advisers to large-scale regeneration projects.



An open and collaborative studio environment where our talented multinational team bring ideas and success to the practice by offering a diverse range of skills and experience to all our projects.


Whatever the size of the project, an interactive design process allows us to explore and test different design options quickly in order to bring new and fresh ideas to the challenges our clients face


This has led to our projects winning or being shortlisted for many prominent awards; recognised for delivering distinctive and sustainable, mixed-use places.
