There’s a new “green” office building in London, on the shore of the River Thames at One Westminster Place in Southbank. The sustainable construction was designed by Sheppard Robson and is wrapped in glass that reflects the sunlight in a rainbow of colors creating a crystal like effect, varying throughout the day.

Other than the looks, the 18 stores high building has an excellent BREEAM (BRE Environmental Assessment Method) rating. How it gets done? A buffer is being created between the glass facade and the building so that the air inside is used for energy. The steel structure is really smart and has a central atrium that brings natural light to the offices so that it uses less electricity. There’s also a roof terrace on top for a great view of t whole area. We love it, how about you? - via World Architecture News
