Interesting Exterior Stair EnclosuresPosted on 02/16/2017 by Architectural Observer • 0 CommentsMany commercial buildings have (or once had) exterior stairwells or staircases. Most need some type of enclosure. Solutions have changed over the years; here are three different sets of stairs – each is an interesting survivor: Sleek 60’s Aluminum This short flight of steps is given stature with a vertical emphasis and sleek styling crafted in aluminum – c. 1960’s. A very elegant interface between handrail and uprights. Iron Stairwell – 2nd quarter of the 20th century White paint makes the unusual design stand out. Just as interesting from the other side! A view inside. Note the manhole cover beneath the first step! And the underside! 70’s smoked plexiglass chic! Smoked transparent panels with rounded aluminum frames… I miss the 70’s. Descending to a basement level never felt so cool.
