Tasi Dome: A Monolithic Dome Home

Taking a Break.

The dramatic sunset skies in Guam bathe Tasi Dome and its owners in pink, orange and yellow light. The double dome consists of a tall prolate ellipse joined to a smaller half-sphere (peeking out from behind the American flag). The deck of the studio apartment above the garage is seen on the right.

Tasi Dome is a Monolithic Dome home finished in 2012 by Stanley Hall and Linda Tatreau of Guam. The main house is 1900 square feet (176.5 m²). The detached garage and its upstairs studio apartment are each 700 square feet (65 m²). Tasi Dome was the first Monolithic Dome Home built in Typhoon Alley, AKA the Western Pacific. It is nestled amongst palm and avocado trees overlooking the Pacific. They named it Tasi Dome because Tasi is the Chamorro word for ocean. The interior is a pleasing mix of white walls, red clay tiles and warm wood accents.

The main house is double-domed, with one dome taller than the other. The taller dome is 36 feet (11 m) in diameter and 27 feet (8.2 m) tall, while the smaller half of the double dome is 25 feet (7.6 m) in diameter and 12.5 feet (3.8 m) tall. The garage and studio apartment are within a 30-foot (9.1 m) half sphere on a 9-foot (2.75 m) stemwall, giving it a total height of 24 feet (7.3 m).

In the early 2000s, they were having lots of conversations about what their dream home would look like when Linda discovered Monolithic Domes. They were drawn to the domes because they knew they wanted to live near the ocean in a home that was strong enough to withstand tropical storms. The couple began building Tasi Dome in 2008 after Stanley attended a 2006 Monolithic Dome Builders Workshop. They did most of the construction themselves.

In May 2023, Typhoon Mawar struck. It was the strongest typhoon to hit Guam since 2002. While Linda and Stanley’s neighbors evacuated the area, Linda stayed in Tasi Dome through the fierce wind and heavy rain. Stanley was in San Diego at the time, and Linda felt safer at home in her dome than anywhere else.

“Linda and I are in awe of the house and a bit disbelieving that anything that wonderful is ours,” Stanley Hall said in 2012. A decade later, the owners still love their home and the safety and security it provides.

A Breathtaking Setting.

Tasi Dome is located on the southern coast of Guam—about 7,000 miles from the US mainland. Linda says she loves that she can go out one door and go swimming in the ocean, or step out another door and go hiking for miles along nature trails.

A Natural Arch.

The archway between the double-domed main house is formed by a saddle designed into the pattern for the Airform. When connecting various domes with saddles like this, the arches create beautiful transitions between living areas.
