Look! A new version of the London Tube & Rail map! This story isn’t about Brexit!

It’s bad, the world, isn’t it? I mean, I don’t want to overstate this, but on this specific day, at this particular point in history, the world is completely bloody awful.

So here’s a new take on the tube map to talk about. Tube map redesigns are my happy place, and don’t you judge me because by clicking this article you’ve implicitly admitted that they’re yours, too.

This one, actually of the London Tube & Rail Map, comes from Luke Carvill, who, like many a graphic designer before him, is using it to show off his skills.

Here’s what he says about it:

“I think Harry Beck’s London tube map is one of the greatest pieces of graphic design in history, but he had no idea how large the network would become. I feel the current map is somewhat cluttered and intimidating to those unfamiliar with it. My redesign focused on simplicity, balance, and beauty.

“The map is mostly used by tourists, who start and/or end most of their journeys in Zones 1 and 2, in order to make the busiest part of the network easier to spot and read, I gave Central London a wide amount of space and framed in an Overground loop.”

Those are indeed the most obvious aspects of his redesign. I’m not entirely sold on the vastly bigger central London, whose acres of white space between lines ends up making the suburbs look cramped in places (the route to Gatwick Airport, included because it takes Oyster cards, ends up bending awkwardly round as if it heads west, not south).

But turning the London Overground routes via Clapham and Highbury & Islington into a loop around central London is very pleasing indeed. And replacing the ugly grey shading to represent fare zones with tiny numbers is such an elegant solution that it remains a mystery why TfL has never done it.

Another minor detail of which I’m a big fan is the effort to map goes to show that Blackfriars station has an entrance on the South Bank:

Carvill follows designers past in using bold, solid colours to represent the tube, and lighter, hollow lines in pastel shades to show National Rail. This is meant to “draw the attention of the eye towards the busier services”, and mostly works, although inevitably there are exceptions (far more mainline services at Wimbledon, say, then there are tube ones at Roding Valley). The map also uses slightly different colours for different Overground or tram services, to make it clear whether direct services do or don’t exist.

It’s not perfect. Like pretty much every other designer ever, he’s struggled to come up with a way of showing the way certain Elizabeth line stations will connect to multiple tube ones, which seems to bolster my case for renaming those stations. And the Bank/Monument interchange is something of a mess. But on balance, I’m a fan.

There. Wasn’t that more fun than reading about Brexit for a while? You can find more tube mappy goodness here.

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.
