La Dogana Venice; Tadao Ando

Home to Francoise Pinaults art collection, Tadao removed all the internal walls from the last 400 years from this 18th Century Palazzo Grassi. The space remaining was a beautiful 105x75 metre triangle. Ando carefully inserted a limited palette of concrete, glass and steel which is beautifully detailed and reinforces the beauty of the original building.

Ponte della constituzione - Venice by Calatrava

 

Calatrava considered this his most beautiful bridge on its inauguration in 2008 but it has apparently attracted a lot of criticism for its aesthetic and its accessibility (Independent 12 Jan 2014). A POD has been added to the side of the bridge to make it accessible for wheelchair users - however - once they get over this bridge, how do they get over the other bridges in Venice!!

IAUV Main Gate Tolentini Venice

Carlo Scarpa transformed the entrance to this University in 1985. Its classic materiality, using off-form concrete, steel, glass, and travertine. The detailing impeccable; even the stainless steel grate purpose made. Shadow gaps between elements and the ability to know when to leave things rough - and when to contrast that with a higher quality material.
The small internal garden is also special - using a faux fallen doorway to define a small seating area - again of concrete.
