I wonder if we will start playing with non-wood materials?
20 years ago people around here were playing with building with galvanized steel studs and framing members, pushed by the steel industry. Never took off. One small builder used Insulated Concrete Forms on both the foundation and kept going to form the outer walls above ground. Very quiet inside. Used a lot less lumber.
The problem is builders are so resistant to change. So are the trade unions.
