Over 25 years ago, Richard Dudzicki founded RDA to change people’s perceptions of what a home could be. Long before our Passivhaus certification in 2010, we were innovating in the eco-friendly space with sustainable home design for years. Over 200 projects later, we’re still fulfilling Richard’s mission, creating cutting-edge solutions for healthier homes.
Our goal is to design homes that are wholly reflective of your lifestyle, needs, and future while also addressing the evolving needs of our planet. As leaders in the UK’s Passivhaus movement, we embrace our duty to push the building envelope, create more with less, solve complex problems, and use our experience to guide you towards a better, cleaner, more comfortable lifestyle.
