This Living Building Material Could Help Turn London Into a National Park City

Green Block could help make this sight a reality for London and other cities around the world.

A team of landscape designers have come up with the Green Block, a living building material that could help London become a National Park City, the first of its kind.

A team of landscape designers have come up with the Green Block, a living building material that could help London become a National Park City, the first of its kind.

Like many urban centres worldwide, London too is blighted by air pollution, with especially high concentrations of nitrogen dioxide (diesel engines are a big culprit for this one) and fine particulates; a recent study found 9,500 premature deaths per year are attributable to air pollution in London alone, which is a much higher number than previously thought.

A recently launched campaign to turn London into a National Park City doesn’t just aim to improve the air quality of London and the health of its inhabitants, but to turn the city into a place in which people and nature can live more harmoniously together, and where green spaces are valued, enhanced and made more accessible to all.

Unsurprisingly, 84% of Londoners are in favour of the initiative.

To help the Mayor of London, Sadiq Khan, turn this vision into a reality, the landscape team at WATG came up with the Green Block, a living building material, maintenance-free and modular, which is permeated with native wild flower seeds and even has its own irrigation reservoir.


According to WATG, the Green Block can support and enhance biodiversity in London (and any other city) in a number of creative ways. The block could be used to delineate cycle lanes, to green up shop fronts and business facades, create green corridors in between city areas, or as cladding for buildings, and of course they could also bring back greenery to the concreted-over front gardens one sees a lot of in London these days, all the while enhancing biodiversity, improving air quality and turning dull grey areas into beautiful and living green spaces that people enjoy spending time in.

The idea of green walls is nothing new, with the high-tech sensor-filled leafy “living wall” set up in London’s Mayfair district just last year. What makes Green Block different is that it is designed with ease of implementation and accessibility in mind, and it has no high-tech high-maintenance features: the blocks are self-sustaining and can be erected pretty much anywhere in the city.

The Green Block, and green infrastructure initiatives in general, can provide a great way to help combat a number of city problems in one fell swoop, and to provide cleaner air, improved biodiversity, noise reduction, more pleasant surroundings to live and work in, better public health. The provision of pleasant spaces in which people can come together can also help reduce the stress and isolation of city life. 

Together with green transport solutions, such as e-mobility and cycling infrastructure, and a renewable energy focus, it will be an essential strategy for healthier and more sustainable living in the increasingly populated cities of the future.

From Ashes to Hope: Rebuilding Gaza with Greencake

How do you set about mending the destruction caused by years of conflict and rebuilding your home, neighbourhood or city, when political instability make it impossible to get hold of the necessary resources? Two Gazan women set about doing just that, and have come up with a durable and affordable building block made out of waste materials: Greencake.

Smog-Eating-Bicycles to Be Developed in China: But Can We Just Pedal Our Air Clean?

The creative mind behind the smog-eating tower and the smog-jewellery is collaborating with China's largest bike-sharing scheme provider to come up with a fleet of smog-eating bikes for the city of Beijing. But will they just be biting off more than they can chew?

Trees and the City: Treepedia Maps Tree Cover in Cities

Trees don't just make our cities more beautiful, they act as natural air-pollution filters, cool urban temperatures, reduce noise and smell, and attract birds: thanks to trees, our ever more congested cities can be much more pleasant places in which to live. How are world cities doing when it comes to trees? What are the cities with the highest tree density? Treepedia tell us just that.

AirVisual: Tell Me Where You Are, I’ll Tell You What You’re Breathing

Good air quality in cities is a real challenge. Traffic, building sites, roadworks, rubbish trucks: the toxic particles that they generate all pose a serious health threat, and it's one that's invisible to the naked eye. Enter AirVisual.

“25 Years From Now, Transport Will Have to Be Almost Completely Electric”

How can Germany - once held up as a pioneering force in the field of environmental protection - reach its current climate goals? And how can e-mobility help? We talked to Volker Quaschning, professor for regenerative energy systems at the HTW Berlin.

How Green Is E-Mobility? It All Depends on the Power Source and Where the Battery Ends Up

Electric vehicles are currently touted as the most eco-friendly way to get from A to B. But what's the truth behind their supposedly green credentials? We've taken a closer look at their life cycle to see how they really shape up.

Can Leafy, Sensor-equipped ‘Living Walls’ Help Make London Greener and Cleaner?

An engineering firm has constructed one of London’s first ‘living wall’ scaffolding structures on a building site. Good for air and noise pollution, as well as the local scenery, green walls are one example of sorely needed solutions to big-city pollution.

The World’s First Covered Bike Path – Berlin’s Latest Arrival?

An 8.9 km long, covered bike lane, passing right through the heart of Berlin? Amazingly-designed and full of innovative technologies? It might not be as crazy as it sounds: the actual route already exists, and with the help of just a few small changes, the concept could soon become reality. RESET talked to Simon Wöhr, one of the brains behind the scheme.

Air Pollution

The term “air pollution” conjures up a broad array of images – from hazy smog to acid rain and buildings stained from exhaust fumes. Equally broad are its causes and negative effects on human and environmental health. In fact, the vast majority the world’s population is adversely affected by air pollution, perhaps without even realizing it. The good news is, since most air pollution is caused by human activity, it's a problem that all of us can do something about.
