Open House Oslo

Open House Oslo is an architecture festival that invites the public to explore the city’s built environment from the inside. For one weekend each year, private homes and public buildings open their doors, giving visitors the opportunity to enter and see spaces that are not usually accessible. The festival is free and open to everyone, making architecture approachable for a broad audience.

The 2026 edition takes place from 11 to 13 September. Open House Oslo provides a festival program and map to help visitors discover participating places, and shares news and information about the event. The organization also offers information about the festival and ways to get in touch.

Open House Oslo is part of Open House Worldwide, a network of 60 member cities around the world. Through this connection, the festival contributes to an international initiative focused on opening buildings to the public and encouraging people to engage with architecture. Open House Oslo is registered in Norway under organization number 913 370 090.
