With the world’s population expected to reach almost 10 billion people by 2050, there is a need for more sustainable living arrangements. High-rise buildings offer a solution, but the current model is flawed. We currently use concrete and steel to build high and not only is this costly to produce and heavy to transport, but it also comes with a large carbon footprint. But what if we used a natural material that has been around since the beginning of time?
“Our view is that all buildings should be made of timber. We think that we should be looking at concrete and steel like we look at petrol and diesel.”
“I think it’s very realistic to think that someone will build a wooden skyscraper in the coming years. There is a lot of potential that is unrealised for using timber at a very large scale.”
Cross-laminated timber (CLT) is made up of layers of wood glued at 90 degrees to each other, making the material very stable. It is comparable int strength to concrete and steel and is extremely insulated to protect against fires.
This video by The Economist outlines the steps modern architects are taking to improve construction practices. “Wooden skyscrapers are an ambitious and innovative solution to the problems posed by urbanisation,” they report. “Not only are they faster to build, they have smaller carbon footprints than high-rises made of concrete and steel.”
