Jübergtower Hemer - Birk und Heilmeyer Architects

This 23.5m high lookout tower over the city of Hemer, Germany, takes advantage of a hill over the town.

It uses timber members in a simple hyperboloid structure, a structural system that spreads the load evenly through the structure, with a geometry allowing the spreading cylinder to be constructed entirely out of straight, inclined timber members—none are perpendicular.

Designed by Birk und Heilmeyer Architekten, with engineering by  with Knippers Helbig Advanced Engineering,  it was opened in April this year.
