These public conveniences on London's South Bank, close to Jubilee Gardens, were designed by Mark Power for Healthmatic Ltd.  It was because of their location that they were given the affectionate nickname of "Jubiloo".  The architect's website says that, "... The pavilion, with its dramatic canopy is like a vessel moored along the historic riverbank beside Jubilee Gardens." 

With this in mind, the bench incorporated into the building bears a quotation from Anthony and Cleopatra that is thought to have been based on Shakespeare's recollection of Elizabeth I traveling along the Thames.
