London Festival of Architecture: Small sites and Big Belonging with RDA, Guided Tour

We are pleased to announce that planning approval has been secured for Wedged House . A conversion of a three-storey commercial building with basement accommodation into a single dwelling. The project presented a number of design challenges, including an unusual triangular footprint, limited access to natural daylight and an inefficient internal arrangement. Through a comprehensive internal reconfiguration, the proposal transforms the building into a bright and functional home while working entirely within the existing building envelope.

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.
