‘Black Monolith’ office building stands at the threshold of Zagreb, marking the city’s entrance.

Its sculpted volume unfolds through a sequence of shifting forms, generating a subtle sense of movement within an otherwise monolithic figure. Enveloped by a continuous dark glazed façade, the building captures the changing light, sky and urban landscape, allowing reflection and transparency to redefine its appearance throughout the day. The result is an architecture that is both solid and ephemeral—a landmark whose identity is shaped as much by its form as by the atmosphere it reflects.

Project made in partnership with colleague Dražen Plevko, studio Plan četiri d.o.o.

Building a monumental space for the sole purpose of eating is quite unusual. Having in mind how important eating is for us, maybe monumental space is exactly what it deserves.

The Food Court in Arena Centar is imagined to change perspective on what large food halls could look like and to bring a new level of eating experience to our guests. It is monumental but approachable, it has 600+ seats but feels cozy, it borrows from shopping mall esthetics but feels like a design space.
