Set on a rocky, pine-covered shoreline, this lakehouse pairs blackened board and batten siding with cedar shingle accents and a grounded base of mixed granite. Inside, a vaulted shiplap great room opens onto a floor-to-ceiling stone fireplace with reclaimed timber mantle, while sage cabinetry and a white oak island anchor a kitchen set against a full-height stone wall. A screened Muskoka room with exposed timber trusses and its own hearth carries the living space toward the water.
