Our History
Richard Dudzicki founded RDA to explore how thoughtful architecture could change the way people live. Over 300 projects later, we continue to bring together creative design and technical expertise, creating comfortable, energy efficient homes through renovations, extensions and new builds.
In 2016, we moved into our current studio in East Dulwich, transforming a former bakery into a working home for the practice. Discover how we transformed The Old Bakery here.

Our Expertise
Passivhaus
Since building our first certified Passivhaus in 2010, we've gone onto complete many more award-winning passive homes.

Retrofit & Renovation
A more sustainable option to improve your home, this is the kind of project we don't just encourage, but truly enjoy.

New build
We love working with a client to bring their vision to life from the ground up, within budget and on time.
Unlocking the potential of constrained sites
For over 30 years, we have worked with sites that demand a different approach. From narrow urban plots and backland gardens to overlooked brownfield land, we bring together creative design, technical knowledge and planning experience to uncover opportunities for new homes.
We consider access, daylight, privacy, neighbouring buildings and construction logistics from the outset, developing proposals that respond to the realities of each site. Alongside our built work, our research and discussions with NLA bring together perspectives from planning, architecture and development to explore how more of London’s small sites can deliver well designed housing.
