About This Home

143 Union Street

Unique 3-bedroom, 1-bath home on a spacious .40-acre lot with a 24x36 shop and separate 240 sq ft tiny house! The thoughtfully updated interior makes excellent use of the space with LVP flooring, mini-split heating and cooling, modern finishes, and distinctive tray and coffered ceiling details. Outside, there’s even more to appreciate. The impressive 24x36 shop offers abundant room for projects, hobbies, equipment, a home workshop, or additional storage. The detached tiny house adds another versatile space with potential for guest accommodations, a mother-in-law suite, home office, or possible rental opportunity—buyer to verify permitted uses. Enjoy a covered back patio, welcoming front porch, carport, EV charging, lean-to, and plenty of parking for vehicles, trailers, RVs, and recreational toys. The large fenced yard provides room for gardening, outdoor entertaining, pets, or simply enjoying the extra space. Tucked away on a low-traffic dead-end street, this unique property offers a hard-to-find combination of an updated home, large lot, substantial shop, additional living space, storage, and generous parking.
