Steel or Timber Stair

You want to install a stair for your builidng. Need to decide what type of construction should you use for your stair.

Lot depends on what is the type of building, where is the stair, what is the asthetics required.

In a residential building, probably what matters most is the asthics for a millionaire residence, cost and asthetics for a middle class house and probably just cost for a low end residential.
