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.
