The programme covers the newest solutions in materials, transformation of existing buildings, planning and regulation. Contributors come from both Norway and abroad, bringing projects, experience and inspiration for architecture on nature's terms.

For politicians, real estate developers, contractors, trades and planners, this is a chance to get an overview of what actually works, in a single afternoon.

The day alternates between short talks and panel conversations, and an introduction to the main exhibition. When the conference ends, the evening continues with the opening party in the church, where you can meet the people behind this year's projects.

"What if nature comes first?", Thursday 17 September 2026, 12:00, Sofienberg Church, Rathkes Gate 18, Oslo.

The solutions already exist
The title of the 9th edition of the Oslo Architecture Triennale is a question: what if nature comes first? The construction industry accounts for one third of all waste globally. That also means the industry holds one of the biggest opportunities to turn things around.

That opportunity is already being taken. Across the Nordics and Europe there are buildings that were transformed instead of demolished, with the numbers adding up. Insulation is being made from wool that used to be thrown away. Neighbourhoods are being planned with soil quality, stormwater and biodiversity in from the first sketch. Trades are rediscovering techniques that let a building be taken apart again. Municipalities are rewriting their procurement so that reuse can actually win a tender.

Eight out of ten buildings in use in 2050 are already standing today. The most important building stock we have is therefore the one we have inherited, and skill in transformation is what the industry will be asking for. That is good news for everyone who already knows the craft.

Nobody gets there alone. Materials are heavy and should stay local, while knowledge is light and should be shared globally. This is why the Triennale gathers architects, planners, researchers, real estate developers, trades, politicians and neighbours for two weeks of conferences, debates, workshops, city walks, site visits and exhibitions.

The main venue is an example of what that can lead to. Sofienberg Church from 1877 is moving from religious services to becoming a local culture hub.

The Oslo Architecture Triennale 2026 runs from 17 September to 1 October.
