    Tucked away on nearly an acre at the edge of Diamond Valley, this is one of those properties that feels worlds away while still enjoying the convenience of town water and sewer. With the river just beyond the property and some of the area’s incredible fly fishing nearby, there is something wonderfully peaceful about this setting. Mature trees, established gardens and winding wooden pathways create a private, tucked-away feel around a home that is truly one of a kind. Expansive outdoor living spaces make the most of the setting. The wraparound deck offers a place to follow the sun throughout the day, from quiet mornings and beautiful sunrises on the east-facing rear deck to long evenings on the west-facing front deck. Tucked throughout the property are charming little garden sheds and outbuildings, a covered firepit beneath a pergola, established garden spaces and plenty of room for outdoor toys, projects and play. A detached garage, additional parking and an asphalt driveway add practicality without taking away from the character of the property. Inside, character and craftsmanship take centre stage. The main floor features English oak engineered hardwood, tongue-and-groove and plaster ceilings, exposed brick surrounding the wood-burning fireplace and custom millwork throughout the kitchen. Concrete countertops add an unexpected architectural edge, while three sets of patio doors fill the main level with natural light and create an easy connection to the decks and outdoors. The main-floor bathroom may be the most memorable room in the house, with a freestanding tub, built-in storage, three playful porthole windows and a repurposed Singer vanity. A sculptural floating concrete staircase leads upstairs, where cork flooring, skylights and live-edge built-in shelving continue the home’s distinctly handcrafted feel. The upper level offers a spacious primary bedroom with skylights, a walk-through closet and direct access to its own incredible private rooftop deck. A second bedroom and three-piece bathroom with walk-in shower complete this level. Downstairs adds two more bedrooms, a three-piece bathroom, laundry, pantry, workshop and plenty of additional storage. Thoughtful improvements over the years include updated plumbing, on-demand hot water, newer doors and windows, a furnace replaced in 2017 and a new water service line installed in 2025. Nearly an acre gives you the kind of space that is increasingly hard to find in town, but it’s the way this property feels that makes it memorable. Gardens to wander through, decks made for slow mornings and summer evenings, little tucked-away spaces to discover, and the river just beyond. A home with history, craftsmanship and a little bit of magic in an extraordinary pocket of Diamond Valley. More details

    There is something about Mountain View Ridge that people wait for — and when the right one finally comes up, you know it. This is the top-floor corner everyone hopes for. A wraparound balcony, big views, walls of windows and that extra bit of privacy you just do not get on the lower floors. And yes, there is an elevator to take you right up. Better yet, there is no waiting on construction. This one is finished, upgraded and ready whenever you are. Inside, it feels almost untouched. The sellers are incredibly particular, and it shows. Upgraded quartz, commercial-grade stainless appliances, beautiful lighting and a custom one-bedroom floor plan that gives you far more living space than you would expect. The kitchen is loaded with cabinetry, anchored by a large island with plenty of room for a proper dining table, while the living area stretches along the windows so the view is always part of the room. The primary suite easily handles a king-sized bed and has its own four-piece ensuite with a custom shower, plus there is a second full bathroom for guests. And then there is Diamond Valley itself. This is one of those towns people discover and then wonder why they did not move here sooner. Mountains in the distance, local shops and restaurants you actually want to visit, trails and outdoor space everywhere, and that small-town feeling where life just seems a little less rushed. Calgary and Okotoks are still close enough when you need them, but at the end of the day, you get to come home here. Mountain View Ridge does not see many top-floor corner units like this — especially ones you can have now. Come see the view, walk the space and decide this is the one you have been waiting for!
