Contemporary living in highly sought-after Lower Sunnyside with true multi-generational and income opportunities. The striking black-on-black exterior and covered south-facing front porch create a bold first impression, framed by mature trees. Inside, 10' ceilings and wide-plank hickory flooring set the tone for an inviting, modern layout. The gourmet kitchen features a waterfall island, gas range, walk-in butler's pantry, and opens seamlessly to the dining area and living room with a gas fireplace. A main-floor study with French doors can easily serve as a fifth bedroom, while a double sliding door leads to the patio for effortless indoor-outdoor flow. One of the rare standout features is the attached 3-car garage - an exceptional find in Denver that provides ample space for vehicles, gear, and storage. Upstairs, the primary suite offers vaulted ceilings, a spa-style bath, freestanding soaking tub, oversized shower, and generous walk-in closet. Three additional bedrooms - including one with its own private en suite - all include walk-in closets. A full laundry room completes the upper level. The real value bonus is the lock-off lower level, fully furnished and designed as a private ADU with its own entrance. With 9' ceilings, a full kitchen, family room, two bedrooms, two bathrooms, and separate laundry, it offers incredible flexibility: rent it out for passive income, host long-term guests, or enjoy a comfortable multi-generational living setup. Perfectly positioned with easy access to everywhere you want to go - just minutes to downtown Denver, a straight shot to Boulder, and quick connectivity to I-70 for mountain getaways - all while being a short walk or bike ride to LoHi, the Highlands, and Tennyson Street for dining, coffee, shopping, and everyday convenience.
