The Police Center Operative Headquarters by Spasoje Krunic is a building that technologically is way ahead of its time. It is an extravagant vision based on futuristic concepts and a sophisticated morphological and constructive technology, which combined, form a unity with distinctive aesthetical features. Owing to its construction and well-formed dynamics, the Operative Headquarters finds its place somewhere on the borderline between architecture and free design. The building is associated with new constructivism, a movement that has never been established in Serbian architecture, nor is it a current trend. Rather, it developed out of a specific set of structural requests imposed on the architect.
