Wien Museum Neu

The winning design for the museum’s renovation and extension emerged from an international competition in 2015. The concept comprises a notable extension of glass and reinforced concrete ‘floating’ on top of the existing building, which opened in 1959 and was designed by Oswald Haerdtl.

A distinctive aspect of the supporting structure design is integrating two separate building components: the existing structure and a new two-storey addition above it. The extension’s substantial cantilever is made possible by two-storey-high steel trusses positioned along the shorter sides of the inner courtyard, combined with a ring-shaped, point-supported steel truss anchored to the building shell on the fourth floor.
