The state capital magdeburg intends to fundamentally redevelop the hypar shell in rothehornpark magdeburg.
He plays this idea out in full-scale participatory projects such as the installation Above and Below: The Hypar Room, 1999, named for the main design principle at work, a hyperbolic paraboloid (or "hypar" for short) in which a horizontal warped plane is formed by straight vertical lines beneath it.
The organization will provide the funding for the construction of 46 houses with the same Hypar Model design built by Habitat for Humanity at Barangay Agujo, Daanbantayan.
