The sweltering conditions inside Leaside Lock, a new-build development in east London, are hardly a secret. Last June, a warning written in big, capital letters was stuck to the window of one flat. \u201cDO NOT BUY THESE FLATS. TOO HOT,\u201d it read.<\/p>\n
It was hard to miss for those walking past the looming high-rises and, after being snapped and posted on social media, the placard has garnered<\/a> more than 500,000 views. More than a year on, during a summer when the UK recorded its second warmest June and fifth hottest July<\/a> since 1884, residents say heat is still an issue.<\/p>\n \u201cWhen I\u2019m trying to fall asleep at night, it gets quite unbearable,\u201d said Lucian Ho, 21, a student who lives near the top of a 28-storey building in the development. Options to cool off in his south-facing flat are limited. \u201cAll I can do is open the window,\u201d he said.<\/p>\n The development is situated in Tower Hamlets, which is the most densely populated borough in the UK. Eighty-one per cent of households live in purpose-built flats, the second highest proportion in England and Wales and double the London-wide rate. The borough has also seen a massive sky-rise boom, with 71 buildings with 20 or more floors being built between 2014 and 2024. To top it off, it ranks poorly for green space. All these factors come together to make living in the borough a hot box for many.<\/p>\n Experts have warned that many of the new homes being built in the UK are not designed to withstand the more extreme summer temperatures<\/a> being seen due to climate change. They have called for the government to update its upcoming future homes standard to include provisions for overheating homes.<\/p>\n \u2018It gets quite unbearable\u2019: Lucian Ho on his balcony in Leaside Lock.

Her thermometer peaked at 33C this summer.<\/p>\n This is my flat. Leaside Lock development in Bromley-by-Bow. They already discovered 2 sections of my MVHR weren’t fitted correctly. It’s still like living in an oven even though this has been ‘fixed’! @GuinnessHomes #leasidelock<\/a> pic.twitter.com\/dAH6GidB0f<\/a><\/p>\n \u2014 Aidan Sheehan (@aidan_sheehan) June 22, 2024<\/a><\/p><\/blockquote>\n When temperatures inside rise above 25C, risks to health rise too, potentially causing or worsening cardiovascular and respiratory issues, sleep disturbance, mental health problems and heat exhaustion.<\/p>\n Monteiro said the heat in her flat causes frequent headaches. \u201cExhaustion, feeling like we\u2019re out of breath. We have experienced feeling very fatigued, even when we wake up,\u201d she said. \u201cWhen we travel abroad we don\u2019t experience as much exhaustion as we do here in the UK, which is definitely to do with the heat.\u201d<\/p>\n Proximity to the busy A12 dual carriageway means residents suffer from dirt and noise if they open their windows. Photograph: Linda Nylind\/The Guardian<\/p>\n The UK Green Building Council has said street trees are a simple and cost effective way to keep homes cool. But Monteiro\u2019s block is situated beside the busy A12 and the streets below are barren of any green space. \u201cIf we have the windows open because of the motorway, we get a lot of the dust and the heat that comes from that,\u201d she said.<\/p>\n She bought a 25% share of the home with her husband for \u00a3121,000. On top of this, she pays \u00a31,264 per month in rent. \u201cIt is my first summer really experiencing these high temperatures and I\u2019m feeling quite unsure about whether I want to continue living here,\u201d she said.<\/p>\n A spokesperson for Peabody, which runs Three Waters, said: \u201cWe want residents to feel comfortable in their homes all year round and work with construction partners to ensure homes are designed with ventilation and shading in mind, considering the risk of overheating.\u201d<\/p>\n They said that since new regulations to reduce the risk of new-builds overheating were introduced in 2022, they had added features to new homes like external shutters that let in daylight but block out heat. \u201cWe\u2019re also looking at materials that help keep homes cooler during summer and warmer in winter,\u201d it said.<\/p>\n Guiness Homes, which runs Leaside Lock, said that of the 440 properties in their blocks they had only received complaints from four homeowners about heat inside their homes, all of whom were given adaptations to reduce temperatures. \u201cThe image you have shared relates to a homeowner who had a specific and unique issue in their property which has been addressed,\u201d they said.<\/p>\n deaths chart<\/a><\/p>\n Farther north in the city sits Kestrel House. The looming 55 metre-tall council block became a symbol of inner-city life after being featured on the cover of The Streets\u2019 debut album Original Pirate Material. It lies along a busy thoroughfare in Islington, which \u2013 after Tower Hamlets \u2013 has the second highest population density in the UK. It also suffers from a lack of green space, and residents have access to an average of 2m2 of green space per capita, the lowest amount of any borough in the UK, according the Friends of the Earth.<\/p>\n Chris Brown, 76, has lived at the top of Kestrel House since 1987. In his 38 years living there as a council tenant, he has found heat an increasing problem. In the summer, temperatures inside his 17th floor flat rarely go below 27C. This year, they reached a high of 30C and in previous heatwaves his thermometer has hit a peak of 35C.<\/p>\n The semi-retired psychotherapist fitted an air conditioning unit in his living room due to fears about what the heat could be doing to his health. \u201cI spent as much time as I can in here, in front of the blast of cold air from the air conditioning unit,\u201d he said.<\/p>\n Brown has a heart condition, diabetes and chronic fatigue syndrome. \u201cIt does cause people to die, so I became worried,\u201d he said.<\/p>\n Hot homes aren\u2019t just uncomfortable \u2013 they can be deadly. During the heatwaves in 2024, UK Health<\/a> Security Agency figures estimated that about 358 people died at home, in part due to extreme temperatures.<\/p>\n Chris Brown said temperatures in his flat in Kestrel House have reached a high of 30C this summer.
