Construction progresses on L33 office building in Ljubljana, completion expected in early 2026

Construction is underway on the L33 office building located on Letališka cesta 33 in Ljubljana, with completion and handover expected between the fourth quarter of 2025 and the first quarter of 2026. The project, managed by Alfi RE and marketed by Colliers, has received its building permit and is progressing according to the planned timeline.

The development will offer 9,731.9 square metres of leasable office space across two underground levels, a ground floor, and five upper floors. A total of 151 parking spaces will be available, including underground and outdoor options. The building is targeting a DGNB Gold certification for sustainability, aimed at reducing operating costs for tenants.

The site is located near major transport routes and amenities. It is approximately 500 metres from Ljubljana’s ring road and just over a kilometre from BTC City, a major shopping and business hub. Public transport connections, restaurants, and parking facilities are all within close proximity.

The L33 office building is designed with flexible floor plans to accommodate various tenant needs. Features include a low add-on factor, economically competitive terms, and the possibility of early access in late 2025.

The project is backed by Alfi RE, Slovenia’s largest alternative real estate fund, with a portfolio valued at EUR 155 million and 16 properties across the country. The fund will retain responsibility for property management following project completion.

Colliers is currently accepting expressions of interest from prospective tenants. Interested parties are asked to indicate their preferred rental area, number of parking spaces, desired move-in date, and company details to receive a tailored offer.
