The original station was built by William Cubitt. The first plan was to construct a building near the Regent's Canal in Islington that would provide a useful connection for London dock traffic, before Robert Stephenson proposed an alternative site at Marble Arch. This was rejected by a provisional committee, and a proposal to end the line at Maiden Lane was rejected by the House of Lords in 1832. A terminus at Camden Town was announced by Stephenson the following year, receiving Royal Assent on 6 May, before an extension was approved in 1834, allowing the line to reach Euston Grove.
