ARCHITECTURAL gems will be open this weekend as part of the London-wide event, Open House.

Across the capital, people will be able to look around structures of all shapes, sizes and uses that are usually closed to the public.

There are some great buildings open in Bexley, Bromley, Greenwich and Lewisham.

Open House founding director Victoria Thornton said: "Open House London highlights the value of good design and aims to open eyes and minds to the City's wealth of architecture.

"Experiencing a building in the flesh can help to understand, appreciate and critique it.

"Open House London hopes to inspire everyone to explore the capital and take an interest in good design for existing and future generations."

Take a look at the list to find out what is open in your borough.
