Fareham Street was renamed from Titchfield Street in 1951.
Titchfield Street, originally named after one of the subsidiary titles of the Dukes of Portland, was established in 1736 between Dean Street and Great Chapel Street.
The street was laid out on undeveloped land in 1736, with the second Duke of Portland granting building leases for various sites along the street. These leases were subject to annual rents without payment of fines and were set to expire in 1799. John Jackson and Joseph Wayte, both carpenters, were among the lessees, with John Morris and John Montigny likely supplying building materials.
The construction of the first houses along Titchfield Street began in 1737. Initially, only a few houses were built, with the process continuing over subsequent years. By 1739, four of the new houses were occupied, and by 1743, all the houses were rated.
Titchfield Street was renamed Fareham Street. The new name was chosen to reflect the past and present names of adjoining villages in Hampshire.
