The 'Ironbank Building' by RTA Studio is by far one of the most oddly-shaped buildings I've encountered in my life. The building is made out of different rooms that are stacked atop one another to create this unique and interesting shape.
However, the architectural mastery of this building isn't limited to the stacked rooms. Connecting 3 of the buildings together are glass walls, creating a transparent and intricate design. Located in Auckland, New Zealand, the 'Ironbank Building' by RTA Studio makes for an awesome office.
