Week 2: Staircase - further exploration

I've decided to go ahead and further develop staircases no. 1 and 2:

Layout for staircase no. 1. The structure has two alternating staircases, one on the exterior, and the other in the interior (highlighted in white)

Two variations on staircase no. 1, one with a bulging midsection and the other with a straight cylindrical centre. A person standing on the mid-level landing (left) gives an idea of scale

I have decided that staircase no. 1 will be solely used for the above-ground gallery space. A friend recently pointed out to me that I can make use of the interior space to create an alternate staircase that complements the outside flight of stairs, going down to the ground level in a reverse direction. The midsection inside the central hollow will feature a landing wide enough for the artist to create and display artwork within.

Staircase no. 2 with perspective elevation cross-section

Interior space will have a finalised headroom of over 2,600 mm and a width of 5000 mm

The below-ground staircase is closely tied to the concept of spatial fluidity - the tube form sneaks around and teases apart the notion of an enclosed space as it crosses in and out of the below-ground "glass cube". The materiality is just as important as a clear tube allows for a greater sensitivity to the entire underground volume as opposed to a simple wall opening along the staircase's length.
