2026 ICF BUILDER AWARD
Specialty Applications
The largest private observatory in North America — a double award-winning showcase of what's possible with Nudura ICF construction.
A three-story architectural masterpiece in Dripping Springs, Texas
The GSR Observatory presented unique construction challenges that only ICF could solve. The building required exceptional thermal stability for sensitive astronomical equipment, structural integrity for a rotating copper dome, and the ability to create curved walls — all while maintaining the aesthetic vision of a world-class private observatory.
We supplied all Nudura ICF forms including specialty radius forms required for the observatory's curved walls — over 2,341 square feet of ICF wall system.
Our team provided technical guidance on ICF installation best practices, helping ensure the complex curved wall sections were executed flawlessly.
Coordinated delivery of materials to match the construction schedule, ensuring the 82-day ICF installation stayed on track.
Worked closely with Austin Touchstone Builders throughout the project, demonstrating the value of strong distributor-builder relationships.
Why Nudura ICF was essential to this project's success
Nudura's radius forms enabled the creation of the observatory's signature curved walls — something impossible with traditional construction methods.
ICF's thermal mass maintains consistent interior temperatures — critical for the sensitive astronomical equipment housed inside.
Reinforced concrete walls support the weight and rotational forces of the custom copper dome system.
ICF's superior STC rating creates the quiet environment needed for focused observation and research.
Continuous insulation dramatically reduces HVAC loads, keeping operating costs low despite the building's unique requirements.
Concrete construction protects valuable equipment from Texas severe weather, including high winds and hail.
"I love, love, love this building — I can't spend enough time in it! Austin Touchstone Builders created something truly extraordinary with my three-story observatory. Their attention to detail, craftsmanship, originality, and creative ingenuity were second to none. The end result is not just a building, but a masterpiece I get to play in and enjoy every single day."
