The Lake Cottage by Toronto-based architecture firm UUfie is a 700-square-foot cabin that mirrors the surrounding forest near Ontario’s Kawartha Lakes. The two-story structure, developed as a home extension, is camouflaged against a leafy landscape with one-way mirrored glass. The steeply pitched dwelling is UUfie’s take on a contemporary tree house with interior and exterior spaces that connect to mimic the experience of living among the branches of a tree.
