This is unusual staircase designed by Atmos studio.
Description from atmosstudio:
These stairs for a residential project (080 – 23MR) took us in an important new direction, harnessing digital production and fabrication to form a seamless and deeply sculptural experience. This page documents a component that we felt was rich enough in detail to merit further exploration and explanation.
The stair is a continuation and intensification of the simple graphic skirting board lines that trace their way through the house. As they turn the corner into the stair void, they expand like a genie released from a lamp, curling and separating and bifurcating from the wall to form the delicate edge of the stair treads, lifting into the air to rise as the veil of the balustrade. This veil hangs gently from above as a series of thin paired threads, softly pulled back at the entry to allow movement past, gently splaying around the corner to meet and carry the arriving visitor onwards & upwards.
The timber edges of each tread tip curl into and up this balustrade wall, snaking upwards to merge into the handrail before trailing downwards once more, merging as handrail and twisting to blend back into the lowest tread. Each edge of tread then converges to blend back into the muter wall opposite, merging into a diagonal splay of lines that compress back into the skirting trim of the rooms below. The pattern of the parquet flooring subtly rotates across each step to mediate the grain of the floors above and below.
