Leslie Green was a British architect who was tasked with designing stations for three London underground lines under construction.
At the time they were known as the Great Northern, Piccadilly and Brompton Railway (today’s Piccadilly line), The Baker Street and Waterloo railway (today’s sensible named Bakerloo line) and the Charing Cross, Euston and Hampstead Railway (which today forms the Charing Cross branch of the Northern line.)
The majority of the stations were completed prior to 1907.
His style was very distinctive and the familiar ox-blood red tiles remain the style to this day for many of the stations he designed.
Here are some sketches of station buildings that Green designed that now house ghost, or abandoned stations on London’s underground. They are done by first laying out a loose watercolour background and then drawing over the top with pen and ink.
