CDJM Architects

Hi there! We’re a small practice from Wimbledon with some big ideas

CDJM Architects are an architecture and design practice founded by husband and wife Cecilia D’Avolio & Jonathan Mills. Their work ranges from large commercial projects to individual homes, focusing on bespoke conversions / extensions.

Encompassing over 25 years of experience in housing, commercial, mixed use, academic and masterplanning schemes, CDJM Architects offer a full range of architectural and design services. From initial site appraisals and concept designs, to navigating projects through the planning / building control stages and on to completion.

Cecilia studied architecture at both The University of Kent in Canterbury and Lille School of Architecture in France, qualifying as an ARB registered architect in 2006, whilst Jonathan studied architecture at The University of Greenwich in London in 2012.

During their combined 25 years of experience Cecilia & Jonathan have worked for some of the UK’s most prestigious Architecture firms, namely AJ 100 practice Rolfe Judd Architects based in Central London & Ray Hole Architects located in Croydon, before establishing CDJM Architects together. 

Both Cecilia & Jon actively engage as established design critics across various disciplines in the UK & France.

Fine Attention To Detail

We Innovate and Bring bespoke Design ideas to Each project

We apply a robust eye to our detail quality and design output, but most importantly we pride ourselves on our client relationships. We understand that true success is achieved through client satisfaction and emphasise the importance of client engagement through all stages of the design process.


We Specialise In all areas of design, from initial concept to detailed delivery

The delivery of our projects would not be possible without the expertise of our high-quality, reliable consultants, a network of contacts we have built throughout our years of experience. These specialists include Structural Engineers, Quantity Surveyors, Mechanical & Electrical Consultants and many more. We have experience in delivering challenging planning and listed building consents in some of the most prestigious areas of the country. Delivering your vision through to completion is something we love to do and we hope to continue to do so in the future.
