A 30x50 shop with concrete floors is perfect for a workshop, storage, or business use. Modern conveniences include Manville water, septic, fiber optic internet, and 200 amp Oncor electric service. The back house (measuring 1848 sq ft per the seller, 1347 sq ft per tax records) features 2 bedrooms, 2 baths, an open floor plan, and an enclosed garage, prewired for a generator. A 36x60 shop with its own 200 amp electrical meter provides even more space for work or storage.
