A detached home on a deep, private lot just off Sulphur Springs Road in Old Ancaster, with a salt-water pool, mature foliage and a lower level already set up for entertaining and wellness. Quiet where you want it, but still well placed for Wilson, Golf Links, Highway 403 and day-to-day conveniences. Welcome to 150 Mansfield Drive. Set on one of Ancaster's more established streets, this is a property with options: move in and enjoy it now, update over time, hold as an investment, or explore future custom-build potential on a strong lot, all subject to buyer due diligence. Site Survey 2007 Available The setting carries a lot of the value here. The lot is notably deep, the rear yard is anchored by a salt-water pool, and the surrounding foliage creates a level of privacy that is increasingly difficult to find. It feels quiet and tucked away, yet you are still minutes to Hamilton Golf & Country Club, Old Ancaster amenities, key commuter routes and highway access. Inside, the home offers a practical detached layout with meaningful bonus space below. The partially finished basement includes an entertainment room, sauna, and a full washroom directly beside it with a rainfall shower feature, giving the lower level a usable retreat-style feel rather than just storage and overflow space. That flexibility matters whether you are buying for your own use, extended family, longer-term hold, or future repositioning. A Hillfield Strathallan College bus stop is reported at the front of the home; buyer to verify. For buyers who understand this pocket, 150 Mansfield is about lot quality, privacy and options in a location that continues to hold long-term appeal.
