This is an incredible house in Hamilton, Ontario by Toronto-based architecture practice Partisans. The central idea is clearly its folding roof, which dips down to accommodate a set of stairs that lead to the roof of the house. At the same time, the sloping roof creates a wave-like enclosure for the indoor/outdoor pool that sits below it.
Partisans is, in my opinion, one of the most creative firms practicing in the city today. This house is a good example of that. I also admire their ability to go deep into materials and construction methods, which is something you need to do when you design forms like the ones you're seeing here. For more photos and information, check out this Dezeen article about the project.
