Bricks can be used to construct ornate and complex shapes. The frontage to the former Spa Road station, Bermondsey (above right) uses bricks of three different colours and incorporates many decorative features. A skilled bricklayer could produce complex shapes using standard bricks, but it was not difficult to produce "specials", that is bricks to non-standard shapes. One of the shafts of Shakespeare Tunnel (above left) shows how bricks can be used to produce a circular structure.
