Consideration: light wood material,easily available and add aesthetics arehigh when filled with a variety ofprofiles and difinishing neatly.

v Weaknesses: cant be traversed byheavy loads, finite width, have a highflexural properties as well as the

construction of wooden stairs is notapplicable in the open space becauseof wood rot easily if exposed to heatand light.
