A €45 million office complex is under construction next to the Ljubljana ring road in the Šiška borough which the investors plan will become part of a new business district in the coming years.

The first building of the sustainability-oriented Westlink Campus project will mostly feature offices. It will comprise roughly 15,000 m2 of commercial space across three underground floors, a ground floor, mezzanine and two floors, with 600 underground parking spots.

The project brings together RP Naložbe of the Ržišnik Perc group, which manages two industrial zones in northwestern Slovenia, and the Austrian real estate manager ATL, which operates a logistics centre at Ljubljana Airport.

The complex is being built in a brownfield area, which means the construction will not have any major impact on the natural environment, Gregor Rožman, CEO of Ržišnik Perc, told reporters on 16 May.

Currently the contractors are working on the underground floors, while construction above ground is expected to begin in September.

The developer hopes to reach rental agreements for 40% of the office space this year and a further 50% in 2025. They expect to obtain an operating permit by July 2026.

Rožman believes that 60-70% of the lessees will be companies moving from existing locations in Ljubljana and its surroundings.

The investors are in the process of obtaining the German sustainability certificate DGNB Platinum. Ržišnik Perc will be in charge of the sustainability management of the building, allowing leaseholders to focus entirely on their business.

These will not be luxury offices but offices of the highest rank in terms of sustainability and functionality, Rožman said. Ržišnik Perc estimates that the demand will continue to outstrip supply of office space in Ljubljana in the coming years.

The group plans at least two similar projects in the area, which could be completed by 2028. Changes to the municipal spatial plan are under way for further development of the area, where Rožman says building a high-rise would make sense.
