This is the Library Quarter. It was built in 2013 in Spijkenisse, Netherlands. It is currently 1700 m^2 and was built very symmetrically triangle. Even though it is called a library, it also contains a supermarket and also offices on that site. On the top side of the buildings are living quarters where people can live as apartments. I think it is interesting that the buildings are all homologous. The color and shape remind me of an ancient village.
