The detrimental health effects of deregulated housing highlight the urgent need for comprehensive regulations and enforcement, according to a study by Bartlett UCL
A room with no windows. A kitchen so small, that your kettle sits on a stool. You open the front door of the office block you live in to find out what the weather’s like.
The nearest food shop, doctor or green space is miles away. Thousands of people across England woke up like this today.
They’re living in deregulated housing because of changes to permitted development rights by the UK Government in 2013.
Only 22.1% of deregulated housing meets national space standards
Disused commercial office blocks and retail units have been adapted, creating around 100,000 dwellings, with roughly 9,000 created last year.
Until 2020, there was no requirement for these homes to have windows. Only 22.1% met suggested national space standards, and only 3.5% had access to any private or shared outdoor space.
“It’s unbearable in summer…the flats are like greenhouses.” – Study participant
Now, a transdisciplinary study from researchers Professor Ben Clifford and Dr Helen Pineo has assembled evidence that living in these spaces is bad for your health – and the effects might be worse for people who are already vulnerable.
Sickness in UK housing
Professor Ben Clifford, of UCL’s Bartlett School of Planning, first became aware of these issues while working on an urban planning research project in 2018.
Noticing how many of these permitted development (PD) residences suffered from substandard space, lighting, ventilation and location, Ben began to investigate and was eventually commissioned by the UK Government to write a report.
Published in 2020, Ben’s report analysed the floor plans of 1,000 properties from 11 different local authorities across the UK.
Using this quantitative data, Ben was able to show how few of these houses met suggested national space standards. Ben’s findings led to the amendment of the PD rights, but many feel the amendments didn’t go far enough.
Looking to further investigate the negative impacts of PD housing on its inhabitants, Ben teamed up with Helen, then based at UCL’s Bartlett School of Environment, Energy and Resources.
Helen’s specialism in urban health research allowed her to provide a range of cohesive frameworks and tools to measure the health and wellbeing of participating PD residents. Ben and Helen designed a pilot study to interview residents and examine the connections between PD housing and health in London.
The health impacts associated with deregulated housing
Supported by funding from Impact on Urban Health, and with help from homelessness charity Groundswell, the academics uncovered evidence of 29 separate negative health impacts – balanced by eight positive impacts, mainly centred around the availability of additional low-cost housing in the area.
“We need far better regulations – and enforcement of these regulations, not just for permitted development but for all housing. But this permitted development is really at the sharp end of the worst kind of examples we’re seeing.” Professor Ben Clifford, Professor of Spatial Planning and Governance, the Bartlett School of Planning.
Some of these issues are geographical, as industrial estates or shopping centres are often located far from important amenities like schools, healthcare, public transport and supermarkets.
Additionally, many of these developments are created without community consultation, and without any developer contributions towards the social infrastructure needed to sustain these residents.
These neighbourhood factors exacerbate the negative health impacts found at the building level. The study found that a lack of residential space, accommodation cooling options, local amenities and perceived safety correlated with low levels of wellbeing.
One of the key findings of the study was that 14% of the residents didn’t have a window they could open. Similarly, 32% did not have a window that they could easily see out of, for example just having skylights.
With lack of ventilation or fresh air to alleviate overheating or avoid damp, mould and rot, some tenants also found themselves saddled with restrictive tenancy agreements that prevented them from installing blinds, curtains, or any other light barrier.
Overheating was one of the most common complaints. As one resident pointed out, “It’s unbearable in summer…the flats are like greenhouses.”
Health equity and the wider context
“The quality of the housing that we studied was mixed, but the small space and poor window provision that we found commonly is really worrying for health and wellbeing.” Dr Helen Pineo, Research Associate Professor, University of Washington, and Honourary Associate Professor, UCL.
Helen points out the implications of this study for the more vulnerable residents.
“From a health perspective, what’s really worrying is that these properties are probably housing people with a number of health problems already. People from lower income, marginalised groups are more vulnerable to poor quality housing, so it has a bigger effect on them.
“Imagine a family with asthma problems, living near a busy road, and being put in one of these homes with poor air quality, no ventilation, overheating problems. It just makes things worse, it’s a real health equity problem.”
Even though the regulations around PD housing were tightened slightly in 2021, there is still no sign that the unregulated housing built prior to this will be subject to any retroactive planning legislation.
Ben feels the study evidences deep problems in UK housing.
“There’s a housing crisis in England, but I think if your solutions lead to more people living in worse quality housing, that’s a false economy that leads to all kinds of other issues.
“We need far better regulations – and enforcement of these regulations, not just for PD but for all housing. But this permitted development is really at the sharp end of the worst kind of examples we’re seeing.
What are the next steps to determine the better regulation of housing?
This study has paved the way for a larger, more comprehensive study, funded by the National Institute for Health and Care Research.
This new project aims to create a new dataset of PD homes across England, cross-referenced with NHS records and compared with a control group, to better determine the health impacts of PD housing.
Interviews to explore lived experiences and environmental modelling equipment in resident’s homes will help the research team form a set of recommendations for policymakers.
However, in light of controversial new extensions to the permitted development legislation, Helen is realistic about the scale of the challenge facing the housing industry.
“The problem is systemic, but a deregulated approach is not working to protect the health and wellbeing of residents. The Hackitt review made very clear that the building regulations system – and the enforcement of that – is broken.” Dr Helen Pineo, Research Associate Professor, University of Washington and Honorary Associate Professor, UCL.
