On March 25th, New London Architecture’s Coffee Conversation brought together a cross section of voices from architecture, planning, development and policy to discuss one of the most urgent questions facing London today: how can small and difficult urban sites make a meaningful contribution to our housing crisis?

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.

We’re excited to share our refined Project Planning Pack, designed to support anyone preparing to embark on a design or building project. Planning ahead is one of the most important steps in ensuring a successful project . This clear, easy-to-follow resource helps you reduce risk , improve your design outcomes, and gain a better understanding of costs and the architect’s role in the process. It also introduces core design principles and provides tools to assess where you’re at before you begin, giving you confidence in every decision. Whether you’re a first-time homeowner, an experienced developer, or simply exploring ideas for a renovation or new build, this pack is an essential companion for your project journey. What’s included: • A structured framework to plan and organise your project • Guidance on core design principles • Insights into costs and the architect’s role • Tools to assess your project readiness We’ve refined this pack to be practical, user-friendly, and aligned with real-world architectural practice. Our goal is to give you clarity, reduce uncertainty, and make the design process as smooth as possible . Access the full Project Planning Pack here:

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.
