Whether you're seeking a full-time retreat or a low-maintenance home base, every inch of this property reflects timeless design and exceptional quality in an unbeatable location. Inside, rich black walnut floors, custom millwork, and leaded glass accents set an elegant tone. The main level flows gracefully from a formal living room with a marble fireplace to a chef's kitchen outfitted with premium stainless appliances, granite countertops, and bespoke cabinetry. A formal dining room framed by architectural columns adds sophistication, while French doors extend the living space onto a serene front porch-ideal for morning coffee or unwinding with a view. Upstairs, the primary suite delivers a spa-like experience with a gas fireplace, private deck, large walk-in closet, and luxurious bath. A second bedroom with en suite bath opens to an expansive deck, and the top-level bedroom makes an inspiring guest room or office with vaulted ceilings, built-ins, and a private balcony overlooking the Flatirons. The lower level includes a spacious rec room, home gym area, powder room, and additional storage, all with the same refined finishes found throughout the home. A generous two-car garage with interior access enhances day-to-day ease. Outside, enjoy multiple private decks, a terraced garden, and a secluded hot tub area-perfect for year-round enjoyment.
