About 3135 11th Street

Welcome to a stunning blend of refined elegance and modern innovation in one of Boulder’s sought-after Newlands neighborhood. Nestled just minutes from downtown and the majestic foothills, this custom-designed residence is a masterclass in craftsmanship and comfort. From the moment you enter, exquisite Brazilian teak flooring, rich knotty alder millwork, and hand-selected granite and stone details set a tone of timeless sophistication. Vaulted ceilings and strategically placed skylights bathe the interior in natural light, creating a warm, expansive ambiance throughout. The main level is thoughtfully designed for both daily living and elevated entertaining, featuring a formal dining room, a gourmet chef’s kitchen with a butler’s pantry, a spacious mudroom, and a flexible office or bedroom. A private studio with its own entrance and half bath offers the perfect space for creatives or remote professionals. The heart of the home is an inviting family room anchored by a striking stone gas fireplace with an antique barn timber mantel. Retreat to the luxurious primary suite, where a private deck offers foothill views, and amenities include a gas fireplace, spa-style bath with a jetted tub, steam shower, and a custom-designed walk-in closet. Upstairs, a loft with panoramic mtn vistas, an en-suite guest suite, a private laundry, and a second deck add to the home's comfort and appeal. The fully finished basement was designed with entertaining in mind—featuring a media/rec room with a wet bar, built-ins, drop-down movie screen, two additional guest suites with Jack-and-Jill bath, a private entrance, and hidden storage spaces. Outdoors, enjoy a secluded backyard retreat with a trellised patio, custom gas firepit, greenhouse, and raised garden beds. Eco-conscious upgrades include radiant floor heat, solar panels, whole-house water and air purification, two sump pumps, a backup generator, and more. Experience unmatched luxury, sustainability, and location!
