WTF

Wooden beams for the floors is even common in houses made of bricks though. I live in the Netherlands and brick houses that have been standing for hundreds of years have wooden floors and the foundation is even standing on wooden piles. Wood isn’t as shit of a building material as you think it is. There are even modern apartments in freezing Northern Europe that are made with cross laminated timber. https://www.dezeen.com/2015/09/23/puukuokka-oopeaa-tallest-wooden-apartment-block-finland-wins-finlandia-prize-for-architecture-2015/

The problem in American buildings isn’t that they are made of wood it’s that they do it cheaply. Stick framing is the most common way to build a house in the US. You can build a very solid house out of wood if you opt for timber framing. Like in Japan there are wooden temples that have been standing for more than a thousand years.
