About Open House Zagreb
Open House Zagreb invites people to discover the Croatian capital through its architecture, buildings and urban spaces. By opening doors to public and private buildings, the organisation brings citizens together with architects, builders, investors and building owners, encouraging a deeper appreciation of the city's architectural heritage and built environment.
Through its programme, the festival encourages conversations about housing, heritage preservation, contemporary architecture and the importance of well-planned urban spaces. It also invites people to reflect on environmental, social and economic sustainability and the role communities play in shaping Zagreb's future. Open House Zagreb is led by the Association for the Promotion of Architecture and Design Zagreb Open House.
