Homeowner Mario and his wife Tete, from Sao Paulo, got inspired by a Tetris bookshelf he saw online, and started designing. His piece was custom fit into his space, built by a woodworking friend.
The shelf is 2.20 meters wide, 2 meters tall and 30 centimeters deep. It's made of MDF wood and the colored parts are Formica sheets.
As you can see in some of the pictures, all the parts are independent of each other so it's a modular project. I can unscrew half of the shelf and use it at another place or I can re-arrange the parts as I see fit (and the holes match too, it's a very artisan project!).
