Kamat & Rozario Architecture in Bangalore, India, has created a highly unique set of concrete bookshelves. The idea behind these amazing shelves was to create an inexpensive divider in order to separate one room in two distinctive spaces. The outside rings are made of precast concrete, similar to those usually seen in culverts. They were then fastened together with bolts and brackets, with a board placed on each of the brackets to form the shelves. There are three shelves per ring, but only two brackets, as the bottom shelf is cleverly held in place by the curve of the ring. Looks sleek from our end! – via
