About this home

Rare 1 acre property featuring a fully updated, taken-to-the-studs, ~$523K remodel on a 1 story home plus an exceptional 900 sqft insulated workshop which includes a 200 sqft office space. Properties offering this combination of land, full remodel quality, and a modern shop setup are extremely limited in this area. The ~$523K in upgrades completed deliver a turnkey, highly functional residence and workspace. The home includes approx. ~1,825 sq ft of added living area, Hardie siding, new plumbing with insulated Pex, fully replaced HVAC system with variable-speed AC and LP furnace, complete electrical upgrades including 200-amp service to both house and shop, new windows, new interior/exterior doors, new trim, and full flooring replacement (LVP/tile/carpet). Kitchen and baths feature custom cabinetry, new granite countertops, soft-close hardware, and full appliance replacements (KitchenAid double oven, microwave, dishwasher, 36” gas cooktop, GE exhaust vent). More improvements include new dimensional roof, blown-in attic insulation, LED lighting throughout, fireplace rebuild, full laundry/utility room addition, new 4th bedroom, privacy fencing, new driveway, sidewalks, + extensive landscape upgrades. The 30’x30’ workshop is a major highlight with insulated walls/roof (closed-cell spray foam), (2) 16’ electric lift insulated doors, 40” soaker sink with water heater, temperature-controlled exhaust system, separate 200-amp service, 30-amp generator plug, dedicated appliance circuits, interior/exterior 220V plugs, conditioned 20’x10’ office with storage, reclaimed-wood exterior accents, and LED interior/exterior lighting. A covered trailer/storage bay with gate access adds even more utility. All with a backyard paradise that backs into the creek. Ideal for owners needing land, shop space, functionality, and a fully modernized home—in a prime Round Rock location with quick access to toll roads & highways, Samsung, Dell, Amazon, Emerson, etc. **Ask for 3-page upgrade sheet
