This spiralling building is the proposed design for a cultural centre in Norway. Look familiar? It reminds us of a stripped-down Guggenheim Museum.
The building was imagined by Portuguese firm Cerejeira Fontes Architects. It's marked by a winding series of overlapping concrete spaces with a cantilevered tail on the end. The elliptical form provides for a green space in the middle, and there's seating for events on the slanted roof. It's just a proposed design, but it looks like it could be a relative of the iconic cake-like NYC institution.
