Built approximately 50 years ago and offered for the very first time, this extraordinary custom-built residence presents a once-in-a-generation opportunity to own one of the area's most distinctive homes. Lovingly owned & meticulously maintained by the same family since the day it was built, this remarkable property is nestled on a quiet street just moments from McMaster University, Hospital, Westdale Village, & the vibrant shops of Locke Street. Unlike virtually any other home on the market, this residence was built almost entirely out of concrete rather than traditional wood framing-a rare method of construction that speaks to its exceptional quality, structural integrity, and enduring craftsmanship. Encompassing more than 3,800 sq.ft above grade and an additional 1,852 sq.ft of finished living space in the basement, the home offers 4 spacious bedrooms, 3.5 bathrooms, and thoughtfully designed living spaces that balance elegance with everyday comfort. From the moment you enter, you're welcomed by a breathtaking floating marble staircase that sets the tone for the refined interiors beyond. Intricate custom millwork, premium finishes, and exceptional attention to detail are showcased throughout, while the custom-designed kitchen serves as the heart of the home, offering the perfect space for both everyday living & entertaining. The outdoor living experience is equally impressive. Designed for hosting family & friends, the private backyard features a built-in outdoor kitchen & BBQ, inviting dining area, fire pit, mature perennial gardens & numerous flowering trees that create a peaceful, park-like setting with exceptional privacy. The finished lower level adds incredible versatility with a second kitchen, a charming old-world bar, and a separate entrance, providing endless possibilities for entertaining or multi-generational living. Being offered for sale for the first time in its history, this is a truly special home that must be experienced to be fully appreciated.
