Sarah Oppenheimer is challenging the distinction between art and architecture with a unique collection of windows and wall openings. Using wall incisions and glass as her mediums, Oppenheimer blurs the line between room and painting. From 2012 to present, Oppenheimer’s work has been featured in the PPOW Gallery in New York City, as well as in Kunsthaus Baselland and Von Bartha Garage in Switzerland.
London's City Hall A 500-metre (1,640 ft) helical walkway, reminiscent of that in New York's Solomon R. Guggenheim Museum, ascends the full height of the building. At the top of the ten-story building is an exhibition and meeting space called "London's Living Room", with an open viewing deck which is occasionally open to the public. http://en.wikipedia.org/wiki/City_Hall_(London)
