Open House London: our highlights

Peek behind the doors of some of London’s most famous buildings at Open House weekend this September

By Things To Do Editors and Katie McCabe |

The annual Open House London weekend gives curious Londoners the chance to venture behind the closed doors of some of the capital’s biggest, most renowned and most secretive addresses for free. Discover hidden histories, find interior inspiration or marvel at the new architectural structures shooting up in the capital. Find our pick of the best buildings to visit at Open House September 2018.

What is Open House London?
A gigantic festival dedicated to making architecture accessible to all. Now in its twenty-sixth year, Open House allows access to private homes, government buildings, historic sites and sparkling new skyscrapers that are normally closed to the public and just waiting to be explored. It’s the largest event of its kind in the world and features walks, talks and tours as well as the chance to nose around some incredible spaces you’d never usually get to enter.

When is Open House London?
It takes place over just one weekend every year. In 2018 it falls on September 22 and 23.

Where is Open House London?
More than 800 buildings across 30 London boroughs will be taking part. It’s a vast sprawl, so you’ll need to dedicate some time to planning your weekend.

How much does Open House London cost?
Brilliantly, it’s all free. Some of the popular events need to be pre-booked, and entry to venues like the BT Tower and Number 10 Downing Street are allocated via a ballot. With the rest you can just turn up on the day – but be ready to queue.

Get a once in a lifetime chance to step behind Britain’s most iconic front door, thanks to these tours by Open House London.

Theresa May won’t be in – but you might see Larry prowling around the place, which is much more exciting, no?

This Grade II-listed building – actually London’s tallest secular building when it opened in 1936 as the administrative HQ of the University of London – balances Portland-stone classicism and art deco elements in perfect harmony.

Sir Christopher Wren’s magnificent place of worship is open all year round to visit, but during Open House, otherwise off-limits areas are open, including an eighteenth-century library packed with leather-bound liturgical texts. You’ll also be to pore over Wren’s first model designs for the cathedral and play spot-the-difference between the plans and the building you’re standing in. Wren’s cathedral is the sixth St Paul’s. Previous ones were put paid to by fires and neglect during the reign of Henry VIII. Go marvel.

If you do, you’ll find yourself whizzing up to the thirty-fourth floor which used to house the famous rotating restaurant and which offers unbelievably good views across the entire city.

Delivered by Jan Kattein Architects and Meanwhile Space CIC, the project has popped up to address the lack of suitable workspaces without whopping prices tags in London. Alongside the self-builds (constructed with help from local community and carpentry students), you’ll find a double-decker bus café, a new public area and pitch space for occasional markets.
