One is a renewable resource, the other isn't..they don't use old growth hardwood to build house frames. Zazing.
Steel frame homes have been built for many years and have 2 major detractions.
In a house fire, even an isolated kitcken fire the odds of frame damage buckling ect are high which in turn adds to repair costs (if repairs are posible). Have the tensile properties of the steel and structural integrity of the frame changed after fire exposure? probably.
Underpinning and/or restumping, eventually all homes need this kind of work, Timber framing will flex and twist where needed.
A steel frame will also do this to a certain degree before buckling or breaking load points.
City dwellings, yeah...Country stuff no way
