For today’s AD Round Up we have five great AD Architecture Classics. The main image belongs to Oscar Niemeyer’s Cathedral of Brasilia. Check out, one of the most inspiring housing project of all times, the Unite d’ Habitation in Marseille by Le Corbusier or the great Church on the Water designed by Tadao Ando. Revisit, one of the icons of New York, the Chrysler Building by William Van Alen. Finally, you can’t miss the particular structure of Johnson Wax Building by Frank Lloyd Wright.
