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.

Our Event: Conversations on Sustainable Living


As part of LFA 2025, RDA Architects invites you to join Director Richard Dudzicki for a guided walk through East Dulwich to explore a series of homes designed to the Passivhaus standard. This event is more than a tour—it’s a conversation about the future of sustainable architecture, how design responds to climate, and how our homes can give voice to a better, more equitable built environment.


Participants will:

  • Walk through East Dulwich to see Passivhaus homes designed by RDA
  • Learn about energy-efficient building principles in practice
  • Engage in open discussion with a leading sustainable architect
  • Experience how low-carbon architecture can integrate with local communities

Why Passivhaus?


Passivhaus is an internationally recognised standard for energy-efficient buildings that dramatically reduce energy use while enhancing comfort and air quality. At RDA Architects, we view Passivhaus not just as a technical solution, but as a platform for responsible, future-oriented design that considers both people and the planet.

Our LFA 2025 event is a way to give voice to these values—and to invite you into that conversation.

Join the Conversation


In the spirit of this year’s theme, “Voices,” we believe that architecture should not only speak—it should listen. We hope you’ll join us in June to explore how thoughtful, sustainable design can contribute to a more inclusive, liveable, and resilient future.

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.

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.
