Open House Oslo (OHO) is a two-day architecture festival where 80 buildings and spaces normally closed to the public open their doors. The festival attracts 15 000 visitors annually, and creates meeting places for architects and the public to share ideas, experiences and a deeper understanding of the value of quality architecture and design.

In 2023, OHO was awarded the City of Oslo’s Art Prize for its contribution to public engagement with architecture and the built environment. The festival was established in 2014 as part of Open House Worldwide.
