Open House Festival 2026 – London, United Kingdom
Overview
The Open House Festival is a city-wide celebration of architecture, design, and urban heritage that grants the public rare access to London’s most iconic and hidden buildings. For nine days, hundreds of private homes, government offices, historic landmarks, and modern skyscrapers throw open their doors for free tours and talks. This festival is a unique opportunity to step inside places that are usually strictly off-limits, from the inner sanctums of 10 Downing Street to the soaring heights of the City of London’s newest glass towers.
In 2026, the festival continues its mission of making the city more accessible and transparent, featuring a diverse program that spans all thirty-three London boroughs. The event highlights the evolution of the city’s skyline, showcasing sustainable housing projects alongside meticulously restored Victorian warehouses. Whether you are an architecture student, a history buff, or a curious resident, the Open House Festival provides a profound look at how London is built, inhabited, and preserved.

FAQ's
How does the ticket lottery work for the most popular buildings?
The most famous sites, like the Royal Courts of Justice or 10 Downing Street, use a ballot system to manage high demand. You must create an account on the official festival website and enter the lottery during the open window in August. Winners are selected at random and notified via email with a specific time slot for their visit, which is non-transferable.
Is there a mobile app to help navigate the hundreds of locations?
Yes, the festival typically launches a dedicated app a few weeks before the event starts. The app includes an interactive map, a "near me" feature to find open buildings nearby, and the ability to save your favorite locations into a personalized itinerary. It is the most efficient way to check real-time updates on queue lengths or unexpected closures during the festival week.
Are the buildings accessible for people with mobility requirements?
While many modern buildings are fully accessible, some historic sites have steep stairs, narrow passages, or no elevators due to their age. The festival website and app use specific icons to indicate the accessibility level of each location. If a site is not fully accessible, volunteers often provide alternative ways to experience the history, such as photo books or ground-floor talks.
Can I take photographs inside the private homes and offices?
Photography policies vary significantly from one site to another depending on the owner's privacy and security requirements. Many public and commercial buildings allow photography, but private homes and high-security government offices often strictly forbid it. Always check the signage at the entrance or ask a volunteer before taking out your camera to ensure you are respecting the host's rules.
Do I need to be an architect to enjoy the tours and talks?
Absolutely not; the festival is designed to be engaging for people with all levels of knowledge. While there are technical details for those interested, the tours focus heavily on social history, the stories of the people who built them, and the impact of the buildings on the neighborhood. The goal is to encourage everyone to appreciate the built environment that surrounds them every day.
