Addendum
Nestled along the shores of Lac de la Mine, in a forested sanctuary of the Upper Laurentians, this contemporary estate redefines the art of living in nature. Built with refined materials -- solid wood, stone, and black steel -- this architect-designed residence embraces its surroundings with rare elegance and a commanding presence.
From the moment you step inside, the double-height great room and floor-to-ceiling windows capture both light and landscape. The central fireplace becomes the heart of the living space, flowing seamlessly into a signature kitchen with clean architectural lines, a substantial natural wood island, high-end appliances, and an integrated wine cellar. The dining area, bathed in natural light, opens directly onto the terrace and the panoramic lake view.
The primary wing offers a true master suite featuring its own fireplace, a generous walk-in closet, and a spa-inspired ensuite with freestanding tub and walk-in shower. Three additional bedrooms, each with its own character and forest views, welcome family and guests in absolute comfort. A second full bathroom and a dedicated powder room ensure both privacy and functionality.
Upstairs, the mezzanine transforms into a games room with billiard table, overlooking the main living area below -- an ideal entertaining space. A four-season sunroom of over 370 square feet extends the connection to the outdoors year-round.
Outside, the landscaped grounds reveal a multi-level wooden terrace, a contemporary pergola housing a hot tub with breathtaking lake views, an outdoor fireplace for starlit evenings, and direct access to the private dock. Forest trails wind through mature woodland down to the shoreline of Lac de la Mine, offering swimming, kayaking, and fishing right at your doorstep.
The attached garage, carport, and expansive terrace complete this property designed for both pleasure and entertaining. Located near Mont-Tremblant National Park and the four-season activities of the Amherst region, this residence represents a rare opportunity to acquire an exceptional private retreat while remaining easily accessible.
Notable features: 4 bedrooms, 3 full bathrooms, living room fireplace, cathedral ceilings, hardwood and polished concrete floors, abundant fenestration, master suite with fireplace, upstairs games room, 4-season sunroom, pergola-covered hot tub, outdoor fireplace, private dock on Lac de la Mine, garage, carport, and direct lake access.
A rare architectural work where luxury meets serenity. Available for private viewing by appointment.
