Sweden already has plenty of "wooden cities" (i.e. from quarters to cities built mostly or entirely out of wood, viz. Haga in Göteborg, Vänersborg, Alingsås, Eksjö, Hjo, Nora and many others) so this is not a new thing. Buildings tend to be lower, 2 or 3 floors instead of the 5+ floor glazed boxes shown in the image in the article. They are made of wood as it comes from the forest, not wood which underwent industrial processing. They also tend to be quite old with plenty of 200+ year old buildings. I live on a 17th century farm, the (wooden) house was moved from its original location to the current one during the great land reform in the early 1800's, most likely around 1823. The house itself is probably from the late 1600's or early 1700's but parts have been added and replaced in the intervening years. Whe I put a new roof on it in 2015 I left the old plank roof ("locktak" - overlapping planks with grooves to catch rainwater and lead it down) in place, it now lies sandwiched between two layers of insulation for the next generation to be found. As long as you keep moisture, arthropods and fire at bay wooden constructions can last for a very long time.
