Wooden buildings reach new heights

Soon, the first tenants will start moving into a new block of council flats in Hackney in north London.
Nothing remarkable about that except Bridport House is built of wood, and it is the largest timber-built apartment block in the world.
It is possibly the biggest timber building of any kind.
Not only that, but a few hundred metres away there is another timber-built block of flats, rather smaller overall, but even taller.
Soon high-rise buildings made of wood may replace many conventional concrete and steel structures, even in the UK, a country with few forests and no modern tradition of building in wood.
