About this home

This beautifully upgraded home provides a suite on the main floor for your parents. Separate entry, alarm, and electrical gives independence while a door into the home allows inclusion in family life. With approximately 5,200 sq. ft. of finished living space across three levels, you will have flexibility for how families live today. This home features newer hardwood floors, generous living and dining spaces, and a refined kitchen with quartz counters, stainless appliances, gas range, coffee and wine stations, dual beverage fridges and RO drinking tap. Upstairs, four spacious bedrooms include expansive primary retreat and second-floor laundry. What truly sets this home apart is the versatile, fully permitted, self-contained main-floor living or work space. Easily accessed from inside the home and outside by its own private entrance, its two generous rooms can function as additional family and play space, a family room and private office, a main-floor bedroom suite, dedicated professional workspace, or independent living for parents, adult children, guests or a caregiver. A kitchenette, full 4-piece bath, gas fireplace, separate electrical panel, 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. This home offers the space to live beautifully today and the flexibility to adapt to whatever comes next. At only $477 per square foot, the value is excellent. Great curb appeal, custom Christmas lights, shows well.
