Set high on a hillside in the rolling countryside of Erin, Ontario, 9255 Sideroad 27 isn’t just a home — it’s a fully realized estate.
Stretching across 46 acres of panoramic land, the property is an ultra-private retreat where English gardens meet classic architecture, and where every inch has been crafted for both grandeur and comfort.
From the moment you pass through the gated entrance and follow the winding, lamp-lit driveway, it’s clear that this is a rare offering.
The custom-built residence spans more than 7,000 sq. ft and has recently undergone a top-to-bottom renovation — with no expense spared. Its classic profile is set against a lush backdrop of colourful perennial beds, intricate stonework, and cascading fountains, all positioned to draw the eye toward the valleys below.
Inside, the home opens with a dramatic two-storey foyer and sweeping curved staircase. A double-tiered formal living room sets the tone for sophisticated entertaining, while a separate dining room and sunken family room offer distinct zones for gathering. An elevated oak-panelled office floats above the main level, accessed by a sculptural staircase that adds architectural flair.
At the heart of the home sits a chef-calibre kitchen by Woodland Horizon, featuring floor-to-ceiling maple cabinetry, quartz countertops, a nine-foot island, and a full suite of premium appliances. A casual dining area with a built-in coffee station completes the space — perfect for early mornings or unhurried weekends.
Upstairs, the primary wing is a sanctuary unto itself. A large sitting room with fireplace, expansive ensuite with six-piece layout, walk-in closet, and dedicated home office make it ideal for those seeking a private, self-contained retreat. Two additional bedrooms and a five-piece bath complete this level's R&R offering.
