Vancouver house by Canadian studio Splyce Design features a lopsided roof that follows the line of the staircase. Stairs between the three floors are at the north-facing front of the house, which is the darkest part of the building. Open stair treads, glass balustrades and a rooflight at the top of the stairwell have been added to increase the flow of natural light here.
