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.

Thinking about renovating your home? Don’t do it alone. We will be explaining how working with an architect rather than just a construction team alone can help you save potential future costs to your project. A big renovation can be exciting, but overwhelming. Costs can spiral, timelines shift and without the right advice, costly mistakes can sneak in. This is where we come in. What is a RIBA Chartered Architect? At RDA Architects, we are RIBA Chartered Architects. RIBA (the Royal Institute of British Architects) is the UK's professional body for architects, setting the gold standard for architectural practice. This means when you work with RDA, you're partnering with professionals who have proven their expertise and commitment to maintaining the highest standards in architecture. But more importantly, we help homeowners like you get the most out of your budget and avoid the kind of problems that can turn a dream project into a nightmare. As shown in the diagram below, RDA (the architect) plays a central role in your project, acting as the hub for information exchange and coordination between the client, design team, and contractor team. We work closely with the specialists, engineers, and contractors to develop and communicate the design, ensuring your vision is realised efficiently and within budget, while helping you avoid the common pitfalls that can derail a project.

Imagine your home as a high-quality flask. When sealed properly, it keeps your drink at the perfect temperature for hours. Airtightness in buildings works similarly: it's about creating a continuous, sealed envelope around your home that prevents unwanted air from leaking in or out. Think of all the tiny gaps around windows, doors, or where pipes enter your house. These seemingly insignificant spaces can add up to the equivalent of leaving a window open all year round. In today's world of rising energy costs, where the average London home loses £400-£500 annually through air leakage alone, airtightness has become increasingly crucial. At RDA Architects, with over 25 years of experience in sustainable home design, we've seen how proper airtightness transforms living spaces, offering benefits that go far beyond energy savings: Enhanced temperature control: No more cold spots or drafts Significantly reduced noise pollution from outside Better air quality through controlled ventilation Protection against moisture issues and mould Reduced dust and allergen infiltration Lower heating and cooling costs (typically 70-90% reduction) Passive Mews II: A Modern Marvel of Efficiency

Behind the Scenes: RDA x Sana Open Studio Earlier this month, we had the pleasure of opening our studio doors for a collaborative event with Sana Tabassum- architect, educator, and founder of :scale, a platform that champions emerging voices in architecture. The evening brought together students, graduates, and early-career designers for an inspiring session of portfolio reviews, career chats, and honest conversations about what it really means to navigate the world of architecture today. The studio was alive with creative energy as attendees engaged in one-on-one critiques, informal Q&As, and discussions that ranged from practical job hunting tips to big-picture reflections on the future of design. Sana shared her expertise on building a personal brand, curating meaningful portfolios, and using digital platforms like Instagram and LinkedIn to grow your reach and professional network. What stood out most was the sense of community, an affirmation that spaces like these, where emerging architects can share, reflect, and ask questions, are more essential than ever.

RDA Architects is proud to be participating in the London Festival of Architecture (LFA) 2025, with a specially curated event designed to spark dialogue around sustainable design and future-facing housing. As part of this year’s festival, we are hosting “Conversations on Sustainable Living: A Guided Walk Through East Dulwich,” offering the public a rare chance to explore the principles of Passivhaus architecture in real-world residential settings. You can now book your free place via Eventbrite: Conversations on Sustainable Living – Guided Walk Through East Dulwich About the London Festival of Architecture 2025 The London Festival of Architecture is Europe’s largest annual festival of architecture, with hundreds of events that bring together architects, communities, and the public. The 2025 theme, “Voices,” asks how we listen, who gets heard, and how design can empower underrepresented perspectives—whether social, cultural, environmental, or spatial. This theme is especially resonant for us at RDA Architects, where we believe sustainable design isn’t just about energy efficiency—it’s about creating spaces that reflect and respond to the needs of the people who live in them.
