Pier-Tech Dome Sub-Building

Pier-Tech Sub-Buildings, along with the Add-On Dome Observatory, are manufactured in the USA. Each dome observatory is completely assembled at the factory with the options ordered and thoroughly tested. Then the dome is disassembled and made ready for shipment.

The Pier-Tech cylindrical walk-in sub-building serves as a base for the Pier-Tech Add-On dome. It is constructed with an all aluminum sub-frame and covered with the same material used for the dome skin. This renders a more esthetically pleasing look of the dome and sub-building. The sub-building is available for Add-On domes in the 8' (2.4 meters) to 18' 6" (5.6 meters) range and come in 6' (1.82 meters), 7' (2.13 meters), 8' (2.43 meters), 9' (2.74 meters) and 10' (3.04 meters) heights. Custom heights are also available.
