Can't See the Wood?

It may sound counter-intuitive but there appears to be a good case for using more wood in the construction of high-rise buildings (https://www.theguardian.com/commentisfree/2020/jun/06/want-beautiful-sustainable-and-safe-buildings-use-wood). This material is actually currently banned  in England in the aftermath of the Grenfell fire (we have not yet had a report on the disaster but the fire was in non-wood cladding and the skeleton of the building was largely of concrete and steel). Pretty obviously, you would not want to use thin wood as cladding but this material seems to have impressive properties as a structural element. It is strong, the charring effect means that burning tends to be superficial and wood can be efficiently engineered in factory units to be swiftly (and relatively soundlessly) erected on site. Even better, the generation of wood removes carbon dioxide from the atmosphere whereas concrete production adds enormously to 'greenhouse gas' release. England appears to be out of step with many other countries that are enthusiastically using wood in their construction industries (even for rise-rise properties).
