Description

A nearly century-old property, carefully modernized without losing its character. This 4-bedroom home sits in Oshawa's established Centennial neighbourhood, on the highly coveted Mary St, and features a generous 50 x 134-foot lot with a deep, private backyard. Wide-plank teak engineered hardwood anchors the main floor, while refinished original hardwood upstairs highlights the kind of detail that can't be replicated. The living room has a gas fireplace with custom millwork and oversized windows that set the tone. The primary suite includes a walk-in closet and fully renovated ensuite with glass shower, floor-to-ceiling tile, and freestanding clawfoot tub. Two additional renovated bathrooms serve the home. A separate den with coffered wood ceilings, gas stove, built-in bookcases, and exposed brick provides a relaxing space to unwind. Third level offers flexible space for an office or additional living area. Partially finished basement with recreation room, separate side entrance, two staircases, and bathroom rough-in, provides variety for future plans. The home has many investments and updates with new windows throughout, new stone and stucco exterior with high R-value insulation, updated wiring, plumbing, furnace, roof, AC, water heater, and doors. Outside, mature trees, a Japanese maple, interlocking walkway, and stamped concrete patio offer a private sanctuary in the city. Driveway fits four. Alarm transferable. Steps to highly rated schools, parks, and transit. Minutes to Oshawa Centre, 401, and the GO Train.
