Shamrock Chateau Monolithic Dome Home
The Shamrock Chateau is a Hyperion-style triple Monolithic Dome home in Italy, Texas.
The Shamrock Chateau is a Monolithic Dome home in Italy, Texas at the Monolithic Dome Research Park. The house was constructed in 1999 for Larry and Marilee Byrne—Larry was the chief designer at Monolithic from 1983 to 2016. They named the home Shamrock Chateau in honor of Larry’s Irish and French/Italian ancestry.
The dome structure is three interconnected dome shapes—called the Hyperion—consisting of 30, 40, and 32 feet (9.1 m, 12.2 m, 9.8 m) diameters with a total floor area of 2660 square feet (247.1 m²). The central dome has a large, carpeted living and dining area, a separate family room, and a spacious kitchen. The 32-foot dome includes the main bedroom, bath, and a large home office. The smallest dome includes a guest bedroom, bath, generous storage, and an unusually large laundry area.
An adjacent 20-foot (6.1 m) diameter dome workshop is connected to the main home with a concrete fence.
The house was listed for sale in 2023.
Curved walls and arched openings complement the spacious great room.
