About our studio

4D Studio refers to the importance of the fourth dimension or “spacetime,” combining the three spatial dimensions with time as the fourth dimension. Time adds an extra axis that represents the spacial and temporal dimensions of human interference in complex ecosystems. We are three-dimensional beings but we must as architects imagine changes over time.

We are one of the United Kingdom’s leading architectural firms, with over 25 years of award-winning work.

Every day we create architectural quality based on innovation, experience and human values. This assures sustainable and aesthetic solutions with lasting value for clients, occupants and society.

Our values

We are a collective of architects and designers working together to build a better future. Creating positive change is at the core of our practice. Our ambition to deliver equitable, healthy, and resilient spaces is built upon experience in meaningful community engagement.

A diverse and inclusive work environment is crucial to delivering on these ambitions. Our design teams foster a culture where all voices are heard and the best ideas are elevated. Within and across our studio we continue to advocate for ideas and talent to percolate up.

Our work in areas such as sustainability, materials, digital technology, and fabrication has spanned the entire life of the practice.
