The area along Slavonska Avenue has been divided into four roughly equal plots, clearly intended for four similar office buildings featuring recognizable illuminated facades. This is part of the Matrix Office Park project, launched in 2017 by the Polish investor GTC Group, which originally envisioned the construction of only two buildings.

According to publicly available data, the owner of the first plot (moving from east to west) is Centar za vozila Hrvatske (Croatian Vehicle Center), the second is owned by B-Matrix Nekretnine, the third by GTC Steven Gardens, and the fourth and final plot – currently under construction – by GTC Matrix Future.
On this plot, construction has already reached the first above-ground floor, with reinforced concrete sticking out in all directions, and judging by the registered owner, what else could be sprouting here if not a new Matrix?

Original Idea
The illuminated buildings have been gradually but steadily rising since 2017 and are now considered an iconic symbol along Zagreb’s main avenue.
The announcement of the latest building came in March 2022, as we previously reported, driven by the exceptional interest from buyers. The Polish developer GTC thus decided to expand the Matrix Office Park project in Zagreb by building a third building.

"I am extremely pleased that our Croatian portfolio is growing so rapidly and delivering outstanding results in the Central and Eastern European markets. A new building in a modern business complex like Matrix Office Park is a great opportunity for GTC to further expand and become a leader in real estate development in Zagreb, as well as in implementing contemporary trends," said Arn Willems, GTC Croatia’s general manager, ahead of the construction of the third ‘Matrix.’

Lighting Up the Avenue
The interest has evidently not diminished, as construction of the fourth "addition" to the colorful illuminated business complex is now underway. The site has made significant progress after reports started circulating in January 2025 on construction forums about the pouring of the foundation.

At the current stage, construction has reached the ground level, with the framework being erected and reinforcement sticking out prominently. How exactly the new building will illuminate remains to be seen.

Top Construction Standards
Originally, Matrix Office Park was intended to consist of two buildings, designed to meet the needs of the new generation of companies, entrepreneurs, clients, and employees.
The project was conceived to fulfill the demands of a dynamic and ever-changing environment while providing users with a stimulating and pleasant setting.
