Britain’s housing policy must “ditch its relentless numbers game”

Britain must build more homes – that much is certain. But a relentless focus on how many means we have lost all focus on the types of homes we must be building. This means we risk repeating the mistakes of previous decades, building homes entirely unfit for future generations.

This is the stark conclusion of a new report from Demos, Future Homes. Analysing the trends we expect to be shaping Britain in the future, we find our current approach to housebuilding has not kept pace with these changes. Indeed, we found that one third of the public don’t think new homes will be fit for purpose in thirty years’ time. Putting this right demands a revolution in our approach to housebuilding.

First, new homes must be fit for multigenerational living. This living arrangement is already on the rise: after decades of decline, average household size is rising, in part due to an increase in the number of multigenerational households. But housing design has not kept pace with these changes: our research found that two thirds of the public do not think new homes are not fit for multigenerational living.

We do not bemoan the rise in multigenerational households – quite the opposite. In a time of social isolation, multigenerational living may help to reduce loneliness amongst the elderly, helping them to stay integrated in society and play an active role in family life. More social contact between the young and old could also reduce the scope for intergenerational conflict, fostering mutual understanding between different generations.

Multigenerational housing may also help ease care burdens at both ends of life, making it simpler to look after the elderly, while allowing relatives to more easily help with childcare. It could also reduce the under-occupation of housing by the elderly, freeing homes at the top of the housing ladder. It is no exaggeration to say that in a time of increasing social and political division, building more multigenerational housing could help bring Britain back together – a first step on the path to a more connected society.

That’s why we call on the government to enshrine a commitment to multigenerational housing in its new Future Homes standard. Multigenerational households should also be entitled to council tax discounts and permitted development rights introduced for “granny annexes”, ensuring current housing stock can be made fit for multigenerational living.


We also need to build much more environmentally friendly homes whilst improving the state of our dilapidated housing stock. With the government aiming for net zero carbon emissions by 2050, this will require a radical change to housebuilding – especially when home energy efficiency has not improved since 2015.

To address this we call on the government to reintroduce the zero carbon homes standard and to launch a Green Homes Fund backed by a new, state-backed Green Development Bank. This would allow the government to make ultra-low interest rate loans to fund energy efficiency home improvements, as is widely and successfully done in Germany.

We must also begin to prioritise the creation of green space and gardens when building homes. This isn’t just what the public wants – we found gardens are the most important feature when choosing a home after location – but is good for our health too. Studies show that those living close to green space are more likely to exercise regularly – vital if we are to tackle today’s obesity crisis. That’s why our report calls for the government to introduce a new “green space standard” for all new homes, eventually giving all residents the right to a garden.

We recognise our proposals could increase the cost of housebuilding, potentially raising property prices – a great concern given the state of Britain’s overheated housing market. However, we believe our proposals can be justified for two reasons.

First, much of the recent explosion in property prices derives from land price increases, not construction costs. Therefore, if our changes were introduced alongside sensible policies to bring down land prices, such as a land value tax, their impact on cost would be limited. Second, even if there are additional costs today, the cost of pulling down new homes in just a few decades would be enormous. This has to be avoided.

Homes can be so much more than a roof over our heads, helping us respond to the great challenges of our time – loneliness, climate change, the crisis of care. But this can only happen if Britain ditches its relentless numbers game on housing and begins to care about the types of home we build, not just the number.

Green roofs improve cities – so why don’t all buildings have them?

Rooftops covered with grass, vegetable gardens and lush foliage are now a common sight in many cities around the world. More and more private companies and city authorities are investing in green roofs, drawn to their wide-ranging benefits which include savings on energy costs, mitigating the risk from floods, creating habitats for urban wildlife, tackling air pollution and urban heat and even producing food.

A recent report in the UK suggested that the green roof market there is expanding at a rate of 17 per cent each year. The world’s largest rooftop farm will open in Paris in 2020, superseding similar schemes in New York City and Chicago. Stuttgart, in Germany, is thought of as “the green roof capital of Europe”, while Singapore is even installing green roofs on buses.

These increasingly radical urban designs can help cities adapt to the monumental challenges they face, such as access to resources and a lack of green space due to development. But buy-in from city authorities, businesses and other institutions is crucial to ensuring their success – as is research investigating different options to suit the variety of rooftop spaces found in cities.

A growing trend

The UK is relatively new to developing green roofs, and governments and institutions are playing a major role in spreading the practice. London is home to much of the UK’s green roof market, mainly due to forward-thinking policies such as the 2008 London Plan, which paved the way to more than double the area of green roofs in the capital.

Although London has led the way, there are now “living labs” at the Universities of Sheffield and Salford which are helping to establish the precedent elsewhere. The IGNITION project – led by the Greater Manchester Combined Authority – involves the development of a living lab at the University of Salford, with the aim of uncovering ways to convince developers and investors to adopt green roofs.

Ongoing research is showcasing how green roofs can integrate with living walls and sustainable drainage systems on the ground, such as street trees, to better manage water and make the built environment more sustainable.

Research is also demonstrating the social value of green roofs. Doctors are increasingly prescribing time spent gardening outdoors for patients dealiong with anxiety and depression. And research has found that access to even the most basic green spaces can provide a better quality of life for dementia sufferers and help prevent obesity.

In North America, green roofs have become mainstream, with a wide array of expansive, accessible and food-producing roofs installed in buildings. Again, city leaders and authorities have helped push the movement forward – only recently, San Francisco created a policy requiring new buildings to have green roofs. Toronto has policies dating from the 1990s, encouraging the development of urban farms on rooftops.

These countries also benefit from having newer buildings, which make it easier to install green roofs. Being able to store and distribute water right across the rooftop is crucial to maintaining the plants on any green roof – especially on “edible roofs” which farm fruit and vegetables. And it’s much easier to create this capacity in newer buildings, which can typically hold greater weight, than retro-fit old ones. Having a stronger roof also makes it easier to grow a greater variety of plants, since the soil can be deeper.


The new normal?

For green roofs to become the norm for new developments, there needs to be buy-in from public authorities and private actors. Those responsible for maintaining buildings may have to acquire new skills, such as landscaping, and in some cases volunteers may be needed to help out. Other considerations include installing drainage paths, meeting health and safety requirements and perhaps allowing access for the public, as well as planning restrictions and disruption from regular ativities in and around the buildings during installation.

To convince investors and developers that installing green roofs is worthwhile, economic arguments are still the most important. The term “natural capital” has been developed to explain the economic value of nature; for example, measuring the money saved by installing natural solutions to protect against flood damage, adapt to climate change or help people lead healthier and happier lives.

As the expertise about green roofs grows, official standards have been developed to ensure that they are designed, built and maintained properly, and function well. Improvements in the science and technology underpinning green roof development have also led to new variations on the concept.

For example, “blue roofs” increase the capacity of buildings to hold water over longer periods of time, rather than drain away quickly – crucial in times of heavier rainfall. There are also combinations of green roofs with solar panels, and “brown roofs” which are wilder in nature and maximise biodiversity.

If the trend continues, it could create new jobs and a more vibrant and sustainable local food economy – alongside many other benefits. There are still barriers to overcome, but the evidence so far indicates that green roofs have the potential to transform cities and help them function sustainably long into the future. The success stories need to be studied and replicated elsewhere, to make green, blue, brown and food-producing roofs the norm in cities around the world.
