Upstairs, four spacious bedrooms include an expansive primary retreat, complemented by the convenience of second-floor laundry.What truly sets this home apart is an exceptionally versatile, fully permitted, self-contained main-floor living space.

A kitchenette, full 4-piece bath, gas fireplace, separate electrical panel, laundry rough-in, and sound-dampened, fire-rated separation give the space the infrastructure to function independently when and if desired.The finished lower level extends the home's versatility with a recreation and games area, sound-dampened music room, workshop, food pantry, cold cellar, guest bedroom with ensuite and abundant storage.Outside, 10 ft mature hedges create exceptional privacy around the in-ground pool, raised cedar deck and fully fenced backyard. An attached two-car garage with storage loft and a three-car tree-lined driveway complete this substantial Glenway Estates property.A home with the space to live beautifully today and the flexibility to adapt to whatever comes next.
