King City is estate country — generous lots and executive homes in Kingscross Estates and the village core, plus growing Nobleton and Schomberg nearby. Basements here become theatres, wine cellars, gyms and full guest suites finished to the same standard as the main floors.
This is where our premium catalog earns its keep: furniture-grade millwork, quartz and custom features throughout. Whatever your starting point, we turn that lower level into finished, livable square footage — and real value added to your King City home.
