This building is the only one of its kind in the world, as each of the 11 apartments can rotate 360?.
- Each apartment can spin individually in any direction. One rotation takes a full hour.
- The facades are composed of double sheets of glass, in different colors (blue, gold, and silver) on different floors. This gives a spectacular effect as the floors turn in different directions.
- The apartment rings rotate around a static core used for building services, utilities, and all areas which require plumbing.
- Suite Vollard was a case study for more than 30 companies in Brazil and one from Germany.
- Each apartment was sold for approximately R$ 400,000.00 ($US 300,000.00).
- The first two floors of the building are an Executive Center.

The Dubai building will rotate entirely, not just floor by floor. That's why it's unique.
