Our Studio
We have a diverse portfolio of projects across Europe and Asia, from small private commissions to public buildings and urban planning proposals.
There are two primary strands to the practice: the first is historic conservation architecture applying skills in intelligent conservation and sensitive building design to projects, and the second is grand architecture concerned with cultural and commercial commissions.
We enjoy working on challenging projects of all scales, including many historic listed buildings. We pride ourselves on a high degree of attention to detail and a flair for innovative and modern design.

CDA was founded in 2004 by Chris Dyson, a former senior designer at Sir James Stirling and Michael Wilford Associates, and more recently at Sir Terry Farrell and Partners.
The practice is based in the historic Spitalfields area of London, where Dyson has lived and worked for 20 years, and where many of the practice’s early projects are located.
We are an award-winning, innovative, design studio.
Based in a renovated pub in historic Spitalfields we produce sensitive and inventive designs for sites in London, the wider UK and beyond.
Our studio is run along the lines of An atelier – a French term that refers to a workshop or studio where artists, designers, or craftsmen create their works.
It is a space where creativity, experimentation, and collaboration are encouraged, and where artists can work on their projects, exchange ideas, and develop their skills.
Ateliers can be found in various fields, including painting, sculpture, fashion design, architecture, and more.
They are often associated with the tradition of apprenticeship, where students learn from experienced masters in a hands-on environment.
