About Us

Our History

Almost 30 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.


In 2016 we moved to our current home in the leafy heart of East Dulwich. Discover the story of our office transformation from bakery to studio here.

FAQs

    At RDA, we prioritise our clients. Undergoing a new project can be stressful, so we make sure that your comfort comes first. As a small and highly experienced team, we have the benefit of being able to spend a lot of time developing our client relationships and ensuring that all of your needs, no matter how big or small, are met. 

  • Do you have experience working with public figures?

    RDA has worked with a number of public figures. Due to the private and intimate nature of our work, respecting the privacy and security of our clients is a top priority. For this reason, we offer a non-disclosure option to all clients.

  • What is a Passivhaus?

    To qualify as a certified Passivhaus, a building has to meet rigorous standards ensuring its efficiency. Passivhauses are designed to be highly efficient, so that things like drafts and over/underheating are a thing of the past. By improving the thermal efficiency of your home, it reduces the energy required to heat it, improving your year-round comfort, reducing your energy bills and your impact on the planet.
