Hook conservation area lies in the countryside, approximately two miles west of Titchfield and a mile north of the coast. It was designated as a conservation area in 1974. The conservation area was designated to protect the small industrial hamlet, which was built by William Hornby in the mid-19th century to serve the Hook Estate. It comprises a blacksmith's house, smithy, four workers' cottages and a wheelwright's house. The core of the conservation area is centred on this well preserved group of Victorian estate buildings. The smithy and wheelwright's shop gradually expanded to serve the wider area of Warsash and Locks Heath, providing woodwork and ironwork services for the district.
Fareham Borough Council has made an Article 4 Direction in Hook Conservation Area making a planning application necessary for certain types of development.
An Article 4 Direction means that a planning application must be made where a development may be considered harmful and may affect the character and appearance of the conservation area. The direction does not necessarily mean that the development cannot occur; it just needs planning permission.
