How to Design a home London Architects Retrofit Extension Dulwich
By Richard Dudzicki February 21, 2025
At RDA Architects, we know that designing a home is a personal and transformative journey. That’s why we’ve developed a 5-phase approach to guide you seamlessly through each stage—offering clarity, structure, and confidence from start to finish. From navigating planning permissions to bringing your vision to life with site visits, 3D visualisations, and models, we ensure a smooth and enjoyable experience. Unlike many practices, we integrate sustainability from day one, considering embodied carbon, airtightness, and energy efficiency from the outset.

We’re delighted to share that The Connected House has been shortlisted for the RIBA London Awards 2024—a recognition that celebrates architectural excellence and innovation. Nestled in the heart of The Dulwich Estate’s conservation area, The Connected House is a prime example of how cutting-edge sustainability and technological integration can breathe new life into a mid-century home. Originally designed by Austin Vernon & Partners in the early 1960s, this home stood as a relic of its time—boasting incredible views of London’s skyline but suffering from decades of substandard modifications.

Richard caught up with David Taylor, the editor of the New London Quarterly and New London Weekly covering the following topics: Celebrating 25 Years of RDA Architects At RDA Architects, we’ve always pushed the boundaries of home design, sustainability, and innovation. As we mark 25 years in business, Richard Dudzicki, our founder and a leading Passivhaus specialist, sat down with David Taylor to reflect on our journey, the future of home design, and some unexpected work environments. A Journey Through 25 Years of Architecture Since founding RDA, Richard has been dedicated to creating energy-efficient, forward-thinking homes. As one of the UK’s early adopters of Passivhaus design, RDA has championed sustainability long before it became an industry buzzword. Over the years, our team has tackled everything from ultra-modern city homes to cutting-edge eco-living spaces, constantly reimagining how people live and interact with their environment. Passivhaus: The Future of Home Design During the interview, Richard emphasized the importance of Passivhaus principles—airtight construction, high-quality insulation, and energy efficiency. With increasing energy costs and a growing awareness of our environmental impact, designing homes that work with nature rather than against it is more crucial than ever.

As the founder of one of the UK’s leading PassivHaus design firms, with chilly weather on the horizon we're here to explain how living in a Passivhaus, or low-energy home can keep your home warm throughout the winter, all while reducing your heating bills. Richard Dudzicki, Director RDA Architecture & Interiors  When it comes to staying warm in winter without draining energy or your wallet, PassivHaus design is a game-changer. At RDA Architecture, we’re passionate about creating homes that are as warm as they are efficient, blending advanced technology with thoughtful design to achieve unparalleled comfort. Let me explain how it all works, and why this approach might be just what your home needs.

BEYOND WORDS is a reunion of some of Britain's boldest thinkers from the 1960s. From Archigram, the Avant Garde architecture collective who’s (largely unbuilt) bold designs influenced buildings like the Pompidou Centre. To Ian Hamilton Finlay, a concrete poet, artist and sculptor, who is one of Scotland’s most celebrated and moving artists. Each of the figures featured in this exhibition reimagined the possibilities and the structure of their fields, mostly to initial outrage, but 50 years down the line, their influence is clear.
