When converting a loft space, finding adequate space to fit a staircase where there was never meant to be one can be tricky. The design of this privately commissioned staircase derived from space restrictions within the given space. Its cantilevered design enabled a slender, almost non existent structure allowing maximum head height when accessing the bedrooms beneath it. Base on the Fibonacci sequence for aesthetics. It appears to be floating in space, the steel risers are welded onto thick steel plates bolted directly onto the wall, beneath the plaster board.
