Tooley Street forms part of huge redevelopment works in the London Bridge area of London, involving the station and surrounding areas.
The programme, under Business Improvement District (BID) work includes new restaurants, cafes and bars.
As such, what were once practical archways were now required to be aesthetically pleasing to the eye as well as to stand the test of time.
Turning railway arches into modern working spaces or leisure venues, whilst making a feature of the exposed brickwork, can be difficult.
Conventional processes include metal sheet liners and canopies covering the brickwork which is less aesthetically pleasing and makes inspection of the structures difficult.
