Richard’s Passivhaus Renovation Featured on Channel 4

Extraordinary Extensions Visits Richard Dudzicki's Passivhaus Home

As you may have already seen, Channel 4 recently featured RDA’s Richard Dudzicki, on their programme Extraordinary Extensions, hosted by none other than Tinie Tempah. It was a privilege to be featured on such an inspiring series that celebrates distinctive home transformations. 

As one of the top Passivhaus specialists in the UK, Richard was delighted to share his passion for sustainable design by inviting Tinie on-site in London, during the later stages of the project. 

Over the past six years, Richard and his wife Eva have transformed a 19th-century industrial workshop into an eco-friendly, family-friendly home that's four times more energy-efficient than typical new residential builds. Utilising several key principles of sustainable design, Richard demonstrates his true passion and commitment to living sustainably and responsibly.

As Richard and Eva explain in the show, they wanted to bring in as much light as possible to their modern industrial home. The combination of strategically placed triple glazed windows, skylights, and advanced insulation keeps their home at a perfect temperature all year round, without the need for traditional heating or gas.

Using breathable paint, they reduce the moisture and condensation in the building, helping to insulate their breathtaking home even further. There's nothing cold about their magnificent design, with a unique curved ceiling in their extension, warm tones, and bright accents. Every Passivhaus element works harmoniously for a cosy, warm, and relaxing feel.

Richard's dedication to the Passivhaus movement isn’t strictly a professional commitment, it’s a personal one as well. It’s also one that extends to our entire team and clients as we all work together towards a common goal; to take effective action in the fight against climate change.

On 25 March, Richard will be speaking at NLA’s Coffee Conversation about how London’s most constrained and overlooked sites can play a role in addressing both the housing crisis and the climate emergency. Across the city, small and fragmented plots are often dismissed as too difficult to develop. Backland sites, former garages and leftover spaces within established neighbourhoods are frequently overlooked by conventional development models. Yet collectively they represent a significant and largely untapped opportunity.

There is a particular responsibility that comes with working on an existing building. The Old Timberyard , a former Victorian workshop, offered the opportunity to demonstrate how careful retrofit can honour heritage whilst delivering genuine long-term performance. Behind its retained brickwork and historic fabric sits a carefully executed EnerPHit upgrade. This was not about surface improvements, but a rigorous, fabric-first transformation, reworking a cold, underperforming structure into a comfortable, resilient and low-energy building fit for contemporary use.

Three weeks ago, Heather Faulding and I had the pleasure of presenting at the NLA’s technical briefing on Retrofit and Reuse a CPD-certified webinar on low-energy & high-performance buildings. It was a fantastic session spotlighting some of the most innovative retrofit work. Heather shared her incredible project for Daily Paper in New York: a powerful example of creative reuse, transforming a crumbling structure using over 7,500 soda cans crafted by local communities. The shimmering façade reflected not only light but the heritage of African beadwork a story of culture and circularity woven into architecture.
