OMA has completed the tower, which is now being fitted out as a hotel for the NH Hotel Group, which owns the Nhow brand. When it opens it will have 650 rooms and be the largest hotel in Benelux ? the grouping of Belgium, the Netherlands, and Luxembourg.

The distinctive-shaped building is intended to be both interesting and fun, as well as allowing guests and locals to enjoy the virtues of modern architecture.

"Given how much progressive values ? and consequently modern architecture too ? are under attack these days, I don't think we can stress enough the virtues of either," he told Dezeen.
The hotel is located alongside the RAI convention centre and its distinctive form is a reference to an advertisement column, which was once the tallest structure in the local area.
"When this complex was built, in 1961, this column was the tallest structure in the area, but has since been surpassed by a multitude of much taller office buildings erected nearby," said De Graaf.
