The doors of hundreds of buildings are being thrown open as part of London's annual Open House weekend - so the public can get a chance to see inside some of the capital's architectural gems.
The Oxo Tower on the South Bank, and a new bright yellow office block a few miles to the west, are two newcomers to the event.
Take a tour of both of them - with Louise King of Coin Street Community Builders - and The Yellow Building's lead architect Simon Allford from Allford Hall Monaghan Morris.
