Key Takeaways
- ✓Demographic displacement: London's falling poverty rate is a misleading statistic — Trust for London data reveals it reflects poorer residents leaving the city, not reduced poverty. Families exit fastest, triggering school closures and critical key-worker shortages across teaching, healthcare, and transport sectors, hollowing out the mixed-income character London historically maintained.
- ✓Surface water flooding: London's number-one risk on the city's official risk register — ranked above terrorism — is localized flash flooding from extreme rainfall overwhelming Victorian drainage. Basement flat residents face the highest mortality risk, with expert estimates of 40+ deaths in a single overnight event, yet no targeted public awareness campaign currently exists.
- ✓Thames Barrier vulnerability: Built in the 1980s for a 70-year lifespan, the Thames Barrier is operating far more frequently than designers projected, accelerating wear beyond replacement timelines. A worst-case East Coast storm surge combined with heavy rainfall could overtop or fail the barrier, flooding millions of homes across London's entire tributary river network.
- ✓Overheating in post-1990s flats: Roughly 25 years of London flat construction predates 2022's Part O overheating regulations. Common compounding factors include excessive glazing, single-aspect layouts, and district heating systems operating at as low as 15% efficiency — leaking waste heat year-round into buildings. Renters and leaseholders lack the legal standing or financial means to install remedial measures like external shutters.
- ✓Wildfire-urban interface: Wanstead Flats in East London has burned three times in three years. Research identifies a statistically clear "fire wave" threshold — temperatures above a set point combined with humidity below a set point — that reliably predicts urban grassland ignition. This predictability makes targeted public barbecue and open-flame bans on high-risk days a low-cost, actionable prevention tool.
What It Covers
Journalist Peter Apps, author of *Homesick: How Housing Broke London and How to Fix It*, examines how four decades of housing financialization have eroded London's social fabric, and how three accelerating climate threats — flooding, overheating, and wildfire — will collide with that existing precarity to devastating effect.

Notable Moment
Apps reveals that London's biggest building fires — Grenfell, Lakanal House, and the Spectrum Building — cluster almost exclusively in June, July, and August. On the 2022 forty-degree day, the London Fire Brigade recorded its busiest operational day since the Second World War Blitz.
Episode Transcript
Hello, and welcome to the developer podcast, where we talk about how to make cities worth living in, which often has to do with the spaces between the buildings as much as the buildings themselves. How is the lack of affordable housing changing our cities? And what happens when the housing crisis meets the climate crisis? This week, I'm speaking to Peter Apps, an award winning journalist that has been writing about housing for more than a decade for titles including Inside Housing, The Guardian, The New Statesman, The Times, The Independent, Private Eye, and of course, The Developer. His Orwell Prize winning book, Show Me the Bodies, covers the build up to the Grenfell Tower fire and highlights the moral and policy failures that led to the disaster. His new book, How Housing Broke London and How to Fix It, examines how the housing crisis is threatening the social fabric of London and what happens when precarious housing meets a fast warming city. This conversation is a live interview that was recorded during Festival of Place Climate Resilience, our annual online event that takes a deep dive into how to create climate ready places. If you love this podcast, you will enjoy our in person festival place on June 10 in London with speakers, including author of Feminist City, Leslie Kern, Olympic cyclist, and walking and cycling commissioner, Chris Boardman, and more. And, of course, I'll be there too interviewing people on stage and speaking about how to make places that thrive. Now, without further ado, here's this week's podcast. Hi. Hi, Christine. So it's a little bit different for us we normally speak as an editor and a journalist but today we're gonna be chatting as a journalist and a journalist a little bit. But, welcome here it's really great to be, speaking to you about this book. I really enjoyed and got a lot out of reading it, so thank you for writing it. I mean, you you've written a lot about housing across your career. Why did you decide to write a book about housing in London in particular? Partly personal. I am a Londoner as in born and raised Londoner, as well as living in the city now. So, and I've it's sort of over the span of my life is really like, a real period of change in terms of London's housing. And it's sometimes, you can sometimes forget that, you know, the the the sort of past is actually quite close in terms of this this wasn't always the way London was. So there's a there's a kind of personal connection to it. There's a kind of city I remember that's that's not there anymore. But, on I guess on a broader level, I think the the question of London is a really important one just about the question of cities and how cities are developing. You know, more and more of the world's population live in cities, and that's gonna number's gonna …
