Living room salt water swimming pool

An indoor swimming pool and hot tub (hidden in the back-right) offer year-round swimming. To keep the home from smelling like a typical swimming pool, the water is not chlorinated. Instead, the pools are filled with filter salt-water.

There is a 29-foot (8.8 m) salt-water swimming pool and a three-person hot tub in the living room of this incredible monolithic dome home. Chris Barnes, a former aeronautical engineer who had worked for Howard Hughes, originally constructed the home in 1982 as his own residence. The swimming pool and hot tub use salt-water and a premium, non-chlorine, filtration system to avoid the swimming pool “smell” in the house.

The dome house has 4,470 square feet (415 m²) of living space split between the main floor and a 1,500 square foot (139 m²) second floor. The monolithic dome itself is 60-feet (18.3 m) diameter by 23-feet (7 m) tall with an attached three-car garaged and an extended entryway with drive-through entrance. The home sits on a three-quarter acre (3,237 m²) lot in the middle of Centennial, Colorado, in the greater Denver metro area.

About half of the main floor is the great room with swimming pool. It is open to the upstairs loft area. There are four bedrooms and three bedrooms overall with a master suite downstairs and a guest suite next to the pool. A central, rock covered cylinder encloses a cove with a working water fall. A floating spiral staircase wraps around the rock cove. The upstairs includes another living area plus two bedrooms and a bathroom. The home was featured in numerous media stories — especially when it was for sale in the late 2000’s.

In 2019, the home is for sale again.
