Thanks for the thoughtful response. > The down side of wood is that it doesn't handle wetness well So, vapour barriers are a Very Big Deal then, right ? Or do we have better solutions to the wood/water problem ? I was going to ask "will this bear out over 50, 100(+) years", but I realized I'm putting my desire of how long a building should last... so, question: How long should a (say, 4-10 story apt) last ? Can we get 100 years out of modern one that are being put up ? What do people in the industry punt-around as a figure for the life of a building ? I have a great love of wood -- it seems to work in compression, and in tension, has interesting failure modes, seems easy to work with and is versatile... but I do like the perceived permanence of concrete. Makes for interesting judgment of buildings...
