Malaysian architect Kevin Low created the folded stair as part of the aviary house, a rowhouse renovation.
The perforated steel stair brings light to the space below the stair, all the while appearing to float between the brick walls. Steel pins anchored into the walls support the folded stair, an almost invisible detail that belies the structural integrity of the stair’s construction.
“An added design task was created: the stair had to seemingly float in the space of its bounding walls. The solution was found in perforated steel sheets, cut to width and folded to the dimensions of treads and risers for the provision of structural integrity.
The folded stair was suspended between the stair walls by mild steel pins located at the junctions where each tread met the top of their associated riser.”

“The stair for the aviary house was
fashioned in a straight run along
one side of the terrace party wall
to maximise room width. Garage
in place at a lower basement level
would have resulted in a walk up
at the end of each day a touch
short of welcoming. To bring light
down to the lower stair entry, the
upper flight had to be somewhat
transparent to natural daylight
allowed in from a skylight up top.
An added task was created in the
stair having to be suspended in
the space of its bounding walls,
given the discrepancy of two and
half inches in the separation of
the walls from top to bottom.
The design found perforated steel
sheets cut to width and folded to
treads and risers for the provision
of structural integrity, then hung
off the stair walls on mild steel
pins – solidité sans stéroïdes.”
