It’s been an intense week in ArchDaily starting with the unfortunate news of the passing of Oscar Niemeyer, Brazil’s modernist icon. Also, we published some great project you can’t miss! Our main image belongs to Visiondivision’s Chop Stick, a whole new definition of the phrase “Tree House”. Don’ forget to check two great house in Japan, Shelf-Pod by Kazuya Morita Architecture Studio and KCH designed by Kochi Architect’s Studio. Take a look at OKE, the new culture house of Ortuella, Spain. Finally, visit Fast Track, an amazing installation by Salto AB.
