This is a great retirement or starter home; two bedrooms, one bath. Half of the dome is the living area; the other half is the bath/laundry/sleeping area. It’s 13’ high at the center. There is room for storage above the bedrooms, hall, and bath.804-2BR-400

The building has 804 s.f. of space. These are construction pictures of the design to the left; it was built in the north Texas area only with the bathroom partitioned; no other partitions were installed; instead of the tub, a wider, deeper tile tub was constructed. It is being used as an office.

It was built with a 1.5 ton electric heat pump for heating and cooling; however, after the first winter, and during the first summer the owners realized that 1.5 tons was overkill. The main unit has not been turned on for a year; instead, the dome has been heated with a 1500 watt portable electric heater bought at Home Depot for $20; a 5500 btu (less than 1/2 ton) window unit air conditioner was installed for cooling (bought on sale at Wal-Mart for $89). The owners state that it is the most comfortable, cost effective office they’ve ever had. A typical wood building this size would generally require between two and two and a half tons of heating and cooling in the north Texas area.
