Two RDA Projects Shortlisted for Awards

This Summer has been a busy one for RDA when it comes to awards. We are thrilled to announce that not one but two of our recent projects have been shortlisted for awards.

The Pavilion - Extension of The Year

The Pavilion joins a number of highly respected projects in the shortlist for British Homes Awards Extension of The Year (Under 2,500sqft). Designed by Frank Atkinson in the early 20th century as a summer house on a grand Georgian South London estate, this Grade II listed building is now revived as a beautiful family home through this sensitive, elegant extension. With designs and planning by Luis Trevino Architects, RDA took this project to completion – removing the previous awkward extension and transforming the home into a spacious, contemporary building that made the most of its heritage features.

Modernist Enerphit - Decarbonisation & Net Zero

Having already won Best Green Home 2023, it has been shortlisted by British Homes Awards and the Passive Trust Awards last year. This year Modernist Enerphit is shortlisted for Architect’s Journal’s prestigious Retrofit & Reuse Awards in the Decarbonisation and Net Zero category. This is one we are particularly proud of, as the driving force of RDA has always been sustainable, low energy buildings. Particularly when it comes to retrofits, and this is one of our finest and most challenging. Build by architect Michael Blackstock in the 1960’s, we took part in a lengthy process of deep retrofitting and transforming this drafty, inefficient house into a beautiful low-energy home that retains all the key design features of its Modernist roots.


We wish the best of luck to our fellow nominees, and appreciate your support of RDA. Fingers crossed!

Airtightness in Passivhaus Design: Real-Life Success Stories from RDA Architects

By Richard Dudzicki • July 8, 2025
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

Portfolio Tips to Help You Get Hired: A Guide for Part 1 & Part 2 Architecture Students

By Richard Dudzicki • June 9, 2025
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.

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.

Understanding Your Procurement Options

By Richard Dudzicki • April 30, 2025
Finding the Right Path for Your Project At RDA Architects, we understand that no two projects are the same—each client brings a unique vision, set of priorities, and practical considerations. One of the most important early decisions in delivering a successful project is selecting the right procurement route. Whether you're building from scratch, transforming an existing home, or undertaking a detailed retrofit, the procurement method you choose will shape everything from cost and timelines to quality and creative control. Here’s a breakdown of the three most common approaches, along with our perspective on which may work best for your project.
