    What's special

    Shaded by mature treesButcher block countersOpen shelvingCompact full kitchenWide-plank wood floors

    Modern garden studio with a huge shady yard in the heart of Boulder This is Boulder living with a little more soul: a newly remodeled 500-square-foot detached garden studio with no shared walls that feels like a modern cabin tucked into the middle of town. It's built for someone who wants the energy of Boulder minus the condo and property-management vibes. Walk to CU, Pearl Street, the Creek Path, coffee, food, and downtown, then come home to a quiet, fully fenced quarter-acre lot shaded by mature trees. The backyard is the draw: it's the kind of place where you can drink coffee under the trees, work outside in the shade, read in the grass, or let your dog stretch out while you answer emails. Inside, the space is bright, clean, and efficient, with wide-plank wood floors, a compact full kitchen, butcher block counters, open shelving, dishwasher, in-unit washer/dryer, and a small gas stove that gives the place a warm, cabin-like feel when the weather turns. It's a good fit for a grad student, young professional, remote worker, or anyone who wants something more interesting than a standard apartment. Pet-friendly. Off-street parking. Contact the manager for a showing. One year lease. Landlord covers water and sewer. Pet friendly. Off-street parking.
