St John's Wood was developed from the early 19th century onwards. It was one of the first London suburbs to be developed with a large amount of low density "villa" housing, as opposed to the terraced housing which was the norm in London up to the 19th century, even in expensive districts. Parts of St John's Wood have been rebuilt at a higher density, but it remains a highly desirable residential district, and one of the most expensive areas of London. The station was opened on 20 November 1939 on a new section of deep-level tunnel constructed between Baker Street and Finchley Road when the Metropolitan line's services on its Stanmore branch were transferred to the Bakerloo line. It was transferred along with the rest of the Stanmore branch to the Jubilee line when it opened in 1979. With the opening of St. John's Wood station, two nearby stations on the Metropolitan line were closed. These were Lord's (which had been opened with the name St. John's Wood Road before being renamed St. John's Wood and then Lord's) and Marlborough Road.
St John's Wood is the location of Lord's Cricket Ground, home of Middlesex County Cricket Club and of the Marylebone Cricket Club (MCC), and the original headquarters of cricket. It is also famous for Abbey Road Studios and the street Abbey Road, where The Beatles recorded, notably the Abbey Road album, the cover of which features the band crossing the road. The King's Troop, Royal Horse Artillery was formerly based at St John's Wood Barracks. The regiment moved to Woolwich on 6 February 2012; the barracks is to be demolished and developed as housing. The station building is Grade II listed. The platform design remains the same as when opened in 1939, as designed by Harold Stabler. In 2006 the tiles were cleaned up and replaced. The station has cash machines, Euro cash machines, wi-fi, payphones, escalators and toilets.
