Denver’s Botanic Garden’s, the city’s most well-known set of Usonian structures.

The Boettcher Memorial Conservatory, 1966 by Victor Hornbein and Ed White Jr. This amazing plexiglass and concrete ribbed building is 51 feet high engineering marvel built on the principle of the inverted catenary curve!

The master plan for the gardens was layed out by landscape architect Garrett Eckbo and now features over 30 themed gardens by world famed garden designers.

These distinctive light concrete light fixtures made an appearance in Woody Allen’s science fiction film Sleeper, from 1973.

Victor Hornbein included many abstracted floral designs in his building, including these in the entry to the Memorial Conservatory.

The organic poured concrete designs continue through to the interior, which is lit with indirecting lighting.
