The project is situated in the heart of Rotterdam and survived, as one of the few, the bombing in May 1940. This historic monument, located at the Coolsingel in Rotterdam, was restored by the firm and transformed into multi-tenant office space with general high-end facilities. The project building dates from 1939 and is also known as the building of the Hollandsche Bank Unie. The building was designed by Willem Dudok. Later a semi-circular extension in black marble designed by B. Kraaijvanger was added to a design of Dudok. The rich history of this landmark unfortunately did not prevent the former tenant to leave. A new concept was needed to start a new chapter in its history. Later parts of the building like the bank safe and the black marble expansion were brought together into the interior design. By re-using the remaining qualities, adding new installations, adding flexible glass divisions and new carpets, new tenants flocked for this high-end, low-cots office space.

The carpet on the office floors and in the meeting rooms have a warm and natural look with a touch of subtle gold which find a nice connection to the brass colored frames of the meeting rooms . The linear lines give direction to the space. The flexible rental concept for the tower asked for an inventive approach to partially existing installations.
