With a wraparound porch you'll never want to leave, 55 Cayley is the one you've been waiting for. Perfectly located in one of Dundas' most desirable neighbourhoods, the home is steps from Dundas Driving Park, close to trails, schools, and the vibrant shops and cafés of Downtown Dundas. Accented by original coal gas fixtures, detailed carpentry, and warm woodwork, it radiates charm and character throughout. Inside, soaring 10' ceilings, oak hardwood floors, and oversized windows create a bright natural flow. The main floor offers true one-floor living with a spacious front hall, elegant living room or office, sprawling family room with ornate gas fireplace, generous bedroom, and full bath. A butler's pantry leads into the kitchen, filled with original character and framed by garden views. From here, step into the bright sun porch with walkout to the rear gardens. The separate dining room opens out to the side garden, where a 1920s gazebo and stonework create an enchanting, secret-garden setting-perfect for intimate gatherings or quiet reflection. Separate staircases lead to the 2nd floor, where you'll find a rear bedroom or den, full bath, ample storage, and a generous primary retreat with dormer windows, electric fireplace, and walkout to an enclosed terrace overlooking the streetscape and treetops beyond. The lower level provides laundry, storage, and walk-up access to the yard. Outdoors, mature gardens, multiple sitting areas, a powered garage and separate studio space, long driveway, and versatile outbuilding add practicality and flexibility. Set on a rare double-wide lot of more than 0.25 acre, this property offers space, privacy, and presence rarely found in Dundas.
