Open House Slovenia returns on 11–13 April with a carefully curated programme of over 70 architectural projects opening their doors to the public across the country. Now in its sixteenth year, the festival invites visitors to discover the richness of Slovenian architecture through free expert-led guided tours of private residences, public institutions, cultural landmarks, and contemporary buildings.

The 2025 edition is held under the honorary patronage of the President of the Republic of Slovenia, Dr Nataša Pirc Musar, and takes place under the continent-wide theme of “Future Heritage” as part of the Open House Europe 2025 programme. The theme reflects on how today’s spaces and architectural practices shape the cultural legacy of tomorrow, inviting critical reflection on what is preserved, valued, and passed on. This year, Open House Slovenia aims to highlight innovative approaches to preservation, the balance between respecting tradition and local character, and responding to the complex challenges of the contemporary world.

The festival’s programme brings together a diverse selection of projects across Slovenia that was composed by a jury of five experts in the field of architecture and design.

In Ljubljana, as part of the celebration of the 160th birth anniversary of the renowned Slovenian architect Max Fabiani, visitors are invited to join an architectural walk through Fabiani’s Ljubljana and visit the historic Mladika building. Fabiani’s work will also be highlighted in a guided tour of the Ferrari Garden in Štanjel. In Dvor, the adaptive reuse of the former Auersperg Ironworks—now home to the Natura 2000 Interpretation Centre—will offer insight into how heritage buildings are being reimagined. Other highlights include the KO-RA Centre for the Elderly in Ravne na Koroškem, the Alpine Houses in the Gorenjska region, the renovation of the Pelikan Photo House in Celje, and a guided tour of the Ankaran Cemetery.

Across all sites, the public will have the chance to engage with architects, learn about design processes, and better understand the values of quality spatial planning. The registration for the tours is mandatory and will be available on the Open House Slovenia website from 2 April.

Open House Slovenia will continue to explore the “Future Heritage” theme throughout the year. Planned events include a special May 16–18 weekend programme titled “Spaces of the State,” curated by architect, curator and publicist Dr Miloš Kosec, and an event later in June commemorating the 100th anniversary of Slovenian modernist architect Milan Mihelič with a visit to the Slovenijales building.

We invite all visitors of Open House Slovenia to participate in the Open Call for Visual Stories—an opportunity to creatively interpret the festival experience and this year’s Open House Europe theme, “Future Heritage”. Submissions can take any visual form, including photography, short film, drawing, or other artistic expressions.
