The story of OH! San Diego
OH! San Diego was founded in 2015 by Susanne Friestedt, a native San Diegan and Point Loma resident, as her way of giving back to her hometown in a meaningful, lasting way. San Diego is the third city in the United States to become an official Open House Worldwide City, joining New York and Chicago in this distinction. The annual event offers a rare behind-the-scenes look at the iconic, cutting-edge and historical buildings that shape our city's DNA. Each site is chosen for its unique contribution through architectural design, historic value, cultural significance, repurposing of space or environmental sustainability.
While enjoying your own custom tours of the best of San Diego's architecture, we invite you to reflect on how these buildings and spaces reflect the challenges and opportunities presented by out history, culture and geography. It's your city! Treasure it!
The story of Open House Worldwide
The Open House concept began in London in 1992 with the aim of fostering a better understanding of architecture outside of the profession and providing experts and citizens a chance to learn about, discuss and debate the merits and challenges of architectural design and urban planning.
The concept resonated with cities across the globe and led to the creation of Open House Worldwide in 2010. Each Open House city if committed to the same core values and together reach across five continents with over one million people participating worldwide.
If you happen to be traveling to one off our sister cities in the future, you are invited to attend their events. Make sure to check the Open House Worldwide website for details.
