Friday
April 17A layered historic urban zone showing how public space, institutional buildings, and incremental renovations coexist over centuries. Less about a single building and more about understanding how Ljubljana evolves without losing continuity. The Lontovž building itself has been rebuilt and repurposed since the Middle Ages — layers of intervention from different centuries sitting on top of each other.
An 18th-century baroque palace repeatedly adapted for modern institutional use. The interest is in how formal historical architecture accommodates contemporary functions without losing its identity. Now houses the National Archives — notable for its painted chapel ceiling and ornate staircase.
A refined example of Jože Plečnik's architecture, adapted for modern governmental use. Demonstrates precision in proportion, material, and symbolic presence. Originally a baroque mansion, Plečnik grafted his classical-modernist detailing — columns, material contrasts, carefully proportioned interiors — onto the existing structure.
Saturday
April 18A former institutional complex converted into a youth-oriented community space. Strong example of programmatic reuse with minimal but strategic intervention. The building has lived several lives — workshops, school, factory, now youth center — each generation adapting the structure for a different social purpose.
A major infrastructure redevelopment project still under construction. The value is seeing real-time construction sequencing, scale coordination, and public works logistics. You'll walk through the active site — new passenger overpass, modernized platforms, and a rethought relationship between rail infrastructure and city.
⚠️ Closed shoes required. Not suitable for children.
🔗 Open Tour Page ↗A mid-century commercial building upgraded for modern energy performance. Focus on envelope improvements, daylight strategy, and mechanical integration within an existing structure. The 1974 building was brought to energy class B, and covered interior atriums were added to bring daylight deep into the floor plan.
A carefully executed apartment renovation emphasizing materials, light, and spatial clarity. Shows how small-scale interventions can dramatically improve livability. Design language of soft curves, marble accents, and subtle stucco detailing with custom millwork throughout.
✨ Bonus options for Saturday:
A 1960s semi-detached house where the architects took the philosophy of 'intervene as little as possible.' Keeps the original structure and character, making only the changes needed for contemporary living standards. A case study in restraint and knowing when not to design.
🔗 Open Tour Page ↗Sunday
April 19A small but highly regarded adaptive reuse project on a compact, constrained site. The strength is in precision — how minimal moves produce strong spatial outcomes. Called the 'industrial chapel' for its spatial quality: high ceilings, raw structural elements, careful insertions of new material. Plečnik Medal 2024 winner.
A guided walk through a former industrial zone now transitioning into mixed-use housing and urban fabric. Gives you macro-scale context: how cities evolve economically and spatially over time. Covers how worker housing, public spaces, and industrial buildings were planned as a unified ensemble, and what's happened as the area transitions.
⚠️ Walking tour, 1.5–2 hours. Wear comfortable shoes. Exact meeting point confirmed at booking.
🔗 Open Tour Page ↗A temporary theater created within a 1960s industrial structure during renovation of Slovenia's National Drama Theatre. One of the strongest examples of creative reuse under constraints — the intervention is fully reversible with demountable partitions and modular systems. EUmies Awards 2026 nomination.
Another work by Jože Plečnik, showing how classical language is applied to commercial architecture. Highlights urban presence, facade articulation, and long-term durability thinking. Notable for its distinctive facade rhythm, ground-floor arcade, and the transition between public commercial space and private residential floors above.
✨ Bonus options for Sunday:
A house built with an all-natural material palette: structural wood, terrazzo floors, and clay plasters on the walls. Prioritizes tactile, breathable materials over synthetic alternatives.
🔗 Open Tour Page ↗A new public swimming and sports complex in east Ljubljana, designed around timber pavilion logic with renewable energy systems. A good example of how sustainable public infrastructure can work at a neighborhood scale. Located in Dobrunje, about 20 minutes from the center.
⚠️ East Ljubljana, ~20 min from center.
🔗 Open Tour Page ↗An open-plan residential interior with warm tones and a distinctive soft-green kitchen as its centerpiece. Located in Logatec, about 30 minutes outside Ljubljana by car — worth considering if you have a vehicle and want to see residential work outside the city.
⚠️ Not in Ljubljana — requires a car, about 30 min each way.
🔗 Open Tour Page ↗An 88-unit non-profit rental housing development organized around a central public park. A rare chance to see a completed social housing project in Ljubljana — the tour covers how shared spaces, unit layouts, and community areas were designed as an integrated system.
🔗 Open Tour Page ↗A 1950s row house renovated with minimal interventions. The key move is a new open-stair vertical connection that rethinks how narrow floor plates are used. Practical, middle-scale residential transformation — very transferable to real-world projects.
