Here is another idea for the people having problems when it comes to living space. The Ascending Retreat offers a neat idea in maximizing living space, offering you the proper bedroom solution even when there are staircases that may not necessarily offer the flexibility of being able to get the maximum home interiors you want.
The idea comes from Thiemo Hildebrandt, offering a multi-level bedroom beneath a single flight of stairs. A structure of steel beams produces a daybed, a desk and a couple of little lofts. No part touches the floor, for the entire framework is supported by the staircase and the back wall.
