1957 – One of the First Concrete Complex-Curve Roofs in America

Berghammer was futuristic before the Calatrava! Designed by architect William P. Wenzler and construction completed by Berghammer in 1957, the building on Watertown Plank Road in Elm Grove included one of the first hyperbolic paraboloid roofs in the United States. The roof was made of poured concrete and extended 45 feet beyond the altar. It is said that workmen on the building site were afraid the under-construction roof would collapse, since its flexible shape meant it moved whenever someone walked on it. Once finished, the building was well-received by the national architecture press and religious leaders of the time.
