There is something truly magical about Casa Glenalbyn. Set along an exceptionally wide, quiet street in Mount Washington with very little through traffic, this home enjoys sweeping hillside views, remarkable privacy, and the peaceful atmosphere of a private villa. Open outlooks and beautiful gardens create a feeling of connection to the surrounding landscape, while generous spaces to live, create, and entertain set the stage for a home filled with warmth and possibility. An inviting front patio leads into a beautiful foyer filled with natural light, where natural oak and a custom wood staircase with detailing inspired by midcentury design introduce the home's character. The subtle aroma of fresh wood accompanies the arrival upstairs, where an expansive living room with high vaulted ceilings delivers both the wow and the warmth. Beautiful light, sweeping views, and an open connection to the kitchen create a space that feels breathtaking at first glance and welcoming from the moment you enter. At the heart of the kitchen is an island spanning over nine feet, crafted from honed Breccia Santorini marble. Custom cabinetry, integrated Viking appliances, and bespoke fixtures complement the stone, while a vast kitchen window floods the room with natural light framing views of mature trees and distant mountains. The home currently offers four bedrooms, three bathrooms, a large bonus room and two dedicated laundry rooms, one upstairs and one downstairs. Three bedrooms and two bathrooms occupy the upper level, including one of the home's two distinct primary suites. Downstairs, the second primary suite offers a spacious walk-in closet and a large, private bathroom clad in Roman clay, velvety to the touch. Its subtle variations create a magical sense of warmth, while a freestanding tub invites you to unwind. Also downstairs, toward the back of the home, a large bonus room with a window overlooking the garden offers natural light, views of lush greenery, and exceptional flexibility. Its quiet setting invites focused work, whether envisioned as a music or editing studio, an artist's retreat, or a spacious home office with room for collaborators. Buyers can preserve the bonus room as a creative space or choose additional bedroom space: upon buyer request, the seller will include conversion of the bonus room into a fifth bedroom with a walk in closet, along with conversion of the spacious downstairs laundry room into a full bathroom, retaining the upstairs laundry room.
