How can city car parks help solve the housing crisis?

You too could live in the supermarket car park of your dreams! Terms and conditions apply. Image: BRE Group

There’s an SNL skit I’ve been thinking about a lot lately. It’s called Target Commercial, and part of it is about a woman who drives to a large supermarket car park to sit there in her car and just have a bit of a… moment.

It’s obviously part of SNL’s post-election content – the litany of oh-dear-he’s-actually-going-to-be-president-what-do-we-joke-about-now sketches – but it says something more profound about car parks as spaces. They’re wastelands – barren places functioning as empty hollows into which you can offload worries, emotions, tantrums, rages, or...

Houses.

There’s no particular need to talk about the housing crisis in detail at this point. There is one. If you’ve read anything on this site before, you’ll know about it. If not, have a Google – it’s a real treat. There’s a reason this publication’s unofficial motto is build more bloody houses.

But the problem is there are all sorts of logistical barriers stopping more housing being built in cities. For one, the dastardly evil green belt stops the city spreading its tendrils into England’s green and pleasant land profoundly average patches of nothing that have been unduly blessed. Brownfill sites get snapped up by developers with their eyes on a sole prize – large pots of cash – and with affordable housing quotas so low (and the classification of affordable so high), these developments often just turn into havens for the wealthy; money-banks for investors.

Which is where car parks come in.

Tom Forth runs software company imactivate, and is an Associate at ODI Leeds. One of his many handy data-visualisation projects looks at the space taken up by car parks in some of Britain’s biggest cities – Leeds, Sheffield, Manchester, and Birmingham.

Within the bounds of Manchester’s inner ring road, 9 per cent of the total space is taken by parking – 357,000 square meters. By Forth’s calculations, thats enough space to build 3,570 homes at a density similar to London’s, 10,710 at a Paris-style density, or 17,850 if you want to bring a touch of Barcelona to the Northern Powerhouse.

Do the same thing with the space inside central Birmingham’s ring road, and you can build 3,440 London-esque homes. Sheffield’s equivalent gives you 1,640 homes; Leeds offers 3,540. Cover over all the car parks identified in Ford’s research, and boom – you could have as many as 1.2m homes built. Job done. Everyone can go home.

Only problem, of course, is that it’s not that simple. As much as most people hate car parks, we can’t just do away with them entirely. While it’s true that reducing the infrastructure for cars can, conversely, decrease congestion on the roads, and in cities like Cambridge – where parking is so impossible and/or expensive that it’s not even worth bothering – cycling and public transport become more popular, you can’t just get rid of them all.

For a start, the elderly and disabled are much better off in a world where you can get in a car, park it in a place, and then cover the short distance between the car park and your final destination yourself. Abolishing all car parks would be rather cruel to those people.

Not to mention that covering car parks over entirely would probably bring you back to square one as regards developers screwing everyone over for the sake of some shiny penthouses for nobody to live in.

Mmmm... shiny expensive things. Image: Jim Lindwood / Flickr. 

So, as Boris Johnson taught us, the trick is to have one’s cake and eat it.

With a typically gimmicky name, ZEDpods aim to be the solution. Erected on piles above car parks, they preserve both the original parking space whilst offering cheap and quick-to-build housing above. The dead air space above a parking bay becomes a home for someone to live in.

An open-plan kitchen and living room (with an adjoining bathroom and balcony) takes up the space directly above the car parking space, whilst a mezzanine floor above provides a reasonable double bedroom.

They can be built in a single terrace above one line of parking spaces, or in two facing lines with a communal space in the middle if the car park is bigger.

There are double pods, too – with space for two bedrooms, a larger open-plan dining-living area, and a separate kitchen.

And for the more ambitious-minded car-park owner, the homes can be stacked in two stories, though the construction of these involves resurfacing the car park.

Hypothetically speaking, a developer or – more preferably, a local council or housing authority – could pay a nominal fee to the owner of the car park space (with appropriate legal wranglings), or rent the air space on an annual basis, and built atop the car parks of London, Birmingham, Manchester, Leeds, and so on.

And there’s no shortage of prime spots that could benefit from such a construction. My local large supermarket has a gargantuan car park just metres away from a prime zone two tube station with interchange – which is currently space going completely underused.

North Greenwich – another zone two station with great connections via the Jubilee Line – has all sorts of underused parking space.

There’s a splurge near Neasden.

And that's just in London. There are many national rail stations up and down the country that have wasted car park space that (fairly obviously) sits right next to prime transport connectivity.

Obviously, there are caveats. There are always caveats. They are a plague on both our housing developments.

For one – who wants to live over a car park? It’s often noisy, highly likely to be smelly, and if it’s a supermarket car park then there’s the profoundly mundane rattle of shopping trolleys for most hours of the day.

The plans that BRE Group have offered for the ZEDpods have no clear disabled access either, and there is still the issue of dead space. Just as nobody wants to be alone in a dark car park at night – who wants to walk through dark covered car park at night to get to their front door? The potential of these spaces to become macabre crime hotspots is very real, and apparently ignored in BRE Group’s plans.


It’s clear the plans need a final finesse before they become the grand design to alleviate the housing crisis.

But for too long our car parks have gone unchallenged – leviathan wastelands obstructing the long arc of progress in our cities towards that utopian dream of, you know, people having somewhere to live that they can actually afford.

Even if the steps we can take towards remedying that are mere baby steps – it’s probably better than the nothing we’ve been doing for nigh-on a century.

Pembrokeshire's innovative new eco-hamlet is great. But it should be the size of a city

The opening in January 2017 of an “eco-hamlet” for council house tenants in West Wales is great news. I have nothing but praise for a development which builds houses with a low carbon footprint, using locally grown wood, to make homes which are well insulated and powered by solar energy. It was also quick to build, with large sections being made in a factory and then assembled on site. And it was relatively cheap – at around £70,000 to £100,000 per building, it is certainly comparable to the costs of more conventional builds.

These houses are an inspiration to the construction industry and an aspiration for the home owner. After all, who wouldn’t like to live in a house that had yearly utility bills of £200, rather than the national average of £1,500?

So the problem is not the six wonderful solar houses at Glanrhyd, Pembrokeshire, or the lucky people who will get to live in them (and enjoy shared use of an electric car). The problem is that we’ve seen all of this before – but nothing changes. What we really need is far, far more of them.

I’ve been involved in sustainable construction for nearly 25 years and seen many inspirational developments like Glanrhyd. There’s Julian Marsh’s home in Nottingham, Susan Roaf’s Oxford Ecohouse and the Hockerton Housing Project, to name but a few. The list is long.


Yet while many individuals continue to build these innovative and inspirational structures, we have a construction industry which still responds to these buildings with disdain. One executive from a large well-known house building company told me recently: “This is a new, expensive and untested technology. We just can’t risk building something so new with all the risks to the consumer and at a higher cost.”

But the situation is even worse than the disdain from the mainstream construction industry. Rather than being welcomed, the latest versions of these sustainable buildings are challenged at every turn. The initial response to the Welsh eco-hamlet plans were concerns about the materials, the technology and the design. The houses at Glanrhyd then had more than 20 planning conditions placed upon them. The CEO of Western Solar, the company behing the hamlet, freely admits that nearly half of their research budget went on solving problems they encountered along the way.

Thinking and building big

So it seems this kind of development just isn’t celebrated enough. There is a general atmosphere of mistrust from construction professionals. It is seen as too complex, too expensive, too risky. Yet there are positive reactions, too. Welsh politician Lesley Griffiths had this to say about the new houses in Glanrhyd:

This scheme ticks so many boxes. We need more houses, we need more energy efficiency, we want to help people with fuel poverty. It’s been really good to hear how they have sourced local products. It’s great they’re using local people to build the houses.

Surely we need to take the eco-technology we have and start rolling it out on a much larger scale. To do so would be a massive step in meeting the significant housing shortage (an estimated 125,000 extra new houses are needed every year). It would also address the disrepair of our current housing stock, and help refit the millions of houses in good repair but requiring improved performance in order to achieve the government’s 2050 carbon reduction target.

We must not forget that the 2050 Climate Change target is not some arbitrary political policy, but one based on the environmental challenge facing all of us. We need to play our part in slowing down the speed of climate change and adapting to the changing natural, social and economic environment.

The solar houses in Pembrokeshire are wonderful. But until we start building huge numbers of buildings with similar credentials, we are just celebrating a cottage industry rather than restructuring our urban environment for an uncertain future.The Conversation
