On 25 March, Richard will be speaking at NLA’s Coffee Conversation about how London’s most constrained and overlooked sites can play a role in addressing both the housing crisis and the climate emergency. Across the city, small and fragmented plots are often dismissed as too difficult to develop. Backland sites, former garages and leftover spaces within established neighbourhoods are frequently overlooked by conventional development models. Yet collectively they represent a significant and largely untapped opportunity.

There is a particular responsibility that comes with working on an existing building. The Old Timberyard , a former Victorian workshop, offered the opportunity to demonstrate how careful retrofit can honour heritage whilst delivering genuine long-term performance. Behind its retained brickwork and historic fabric sits a carefully executed EnerPHit upgrade. This was not about surface improvements, but a rigorous, fabric-first transformation, reworking a cold, underperforming structure into a comfortable, resilient and low-energy building fit for contemporary use.

Three weeks ago, Heather Faulding and I had the pleasure of presenting at the NLA’s technical briefing on Retrofit and Reuse a CPD-certified webinar on low-energy & high-performance buildings. It was a fantastic session spotlighting some of the most innovative retrofit work. Heather shared her incredible project for Daily Paper in New York: a powerful example of creative reuse, transforming a crumbling structure using over 7,500 soda cans crafted by local communities. The shimmering façade reflected not only light but the heritage of African beadwork a story of culture and circularity woven into architecture.

What Makes Brownfield Sites Unique? Across the UK’s cities, thousands of small, disused plots sit idle: the remnants of former garages, workshops, and scrap yards. These brownfield sites, often dismissed as too constrained or contaminated for development, represent an untapped opportunity. Yet within these limits lies enormous potential. When approached with imagination and technical rigour, they can become prototypes for compact, sustainable urban living. Projects on brownfield sites are unique in their demand for a precise balance between innovation, practicality, and sustainability; ultimately, every square metre counts. And the result can be one of the most rewarding in contemporary housing design. Our project, Eva’s House , completed in 2005, offers a compelling example. Built on the footprint of two derelict garages in Southeast London, this modest three-storey home demonstrates how a forgotten plot can be transformed into a durable, adaptable dwelling that continues to perform nearly two decades later.

Upgrading a listed home is one of the most rewarding yet challenging projects a homeowner can undertake. Unlike Standard properties, every change must respect strict planning regulations whilst protecting the historic character that makes the building unique. Choices that may seem simple in modern homes such as changing windows, adding insulation, or altering layouts can become complex negotiations between performance, aesthetics and compliance. The key to success lies in working with conservation architects, skilled craftspeople, and heritage professionals who understand both the technical and regulatory landscape. With their guidance, upgrades can be achieved in ways that not only preserve but often enhance the building's long-term performance and beauty. When done right, a listed home can be both energy-efficient and historically authentic, ready to thrive for future generations.

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.
