Over ten years of excellence in Passivhaus design.

We built our first certified Passivhaus in 2010, and since then have gone onto design and build many more.


Our team of experienced architects and certified Passivhaus designers bring beautiful, efficient and healthy homes to our clients. RDA's director and founder Richard's commitment to building sustainable homes has lasted more than thirty years.


We build lasting, comfortable, elegant Passivhauses with confidence and expertise.

"You will be bowled over by the flair, creativity and attention that Richard applies to your project. I ended up with a light, bright, award-winning house so far beyond my expectations. I’m thrilled to recommend such a great practice."

Chiswick Eco Lodge

“We went from frustrated and cold in our home to utterly satisfied. The space is beautiful, functional, quieter and we love not paying for any gas and using solar power.”

Modernist Enerphit

“We were so disappointed with our dark, dingy and poorly organised house. Now it’s like living in a luxury hotel. We are so happy with our new home, and can’t wait to enjoy it for many years.”

Peckham Heights

"The blend of old and new is seamless, and the combination makes people stop in their tracks and smile. Everyone wants to visit, and when they do they want to stay.  We still can’t believe this is our home."

The Pavilion

"Now we have a great family home with open, light-filled spaces with fabulous views over the garden. We love the different zones and rooms for the family that are flexible as our family’s needs change over time!"
