XTH-Berlin inserted staggered floors throughout the building’s 12-metre height to accommodate various living spaces, with bedrooms housed in slanted concrete volumes at the first and third levels featuring flaps that can be used to slide from one level to the next. The house’s entrance contains wardrobes, a bathroom and a spare room that can be hidden by drawing a full-height curtain, while a gap in the ceiling provides a view of the zigzagging levels that ascend to the top of the house.
