The project consists of a stylish complex of rounded design, formed by four similar-looking towers of different heights, ranging from 5 to 18 storeys. Besides 60,000 m² of offices, Quatuor offers its occupants meeting rooms, a cultural center, restaurants and bars, co-working spaces, a gym and even a bank branch.
The parking areas have space for 300 bicycles and 314 cars underground. Thirty percent of the parking spaces are equipped for electric vehicles.
The construction of the complex required some delicate and complicated preliminary work including heavy structural demolition works - of the Noord building and its 40,000 m² of offices - the removal of foundations and even decontamination of soil.
