Staircase, Metal Tread, and Metal Railing Like the pavilion holding the public spaces, the structure containing the bedrooms is clad in glass on the interior sides facing the courtyard, allowing a constant connection to the outside. Agustina Rodriguez (with dog Lupe) designed the steel stairs leading from the mezzanine-level home office to the master bedroom below. The stairs were fabricated by Austin-based Steel House MFG.
guard rails and handrails have specific dimensional requirements (e.g., 1-1/4" - 1-1/2" diameter gripping surface with 1-1/2" clear space between the rail and the wall) stairs have max. riser height = 7" and minimum tread length = 11"; also nosing profile should be "continuous" and smooth rather than articulated.
