Portslade Old Village Conservation Area could be extended.
The boundary is being reviewed for the first time since 1997 having remained unchanged since it was created in 1974.
Brighton and Hove City Council’s conservation team is mapping changes to the Old Village since then.
The aim is to protect the village and its outlying buildings.
The heart of the Old Village is medieval in layout and the area includes a Norman church – St Nicolas – as well as the old manor and a former brewery.
The review will detail what makes the area unique and explore possible amendments to the boundary such as including the 19th century Loxdale property.
Loxdale features a tall red brick wall which screens the house from the road.
The review will also consider whether to brewery workers’ houses in Southdown Road and North Road should be included in the conservation area.
The homes were built in the late 19th and early 20th century, both of which are important to the historical development and character of the area.
Once complete, the revised conservation area will be used in conjunction with planning policies to ensure that it is protected.
Councillor Geoffrey Theobald, the council’s cabinet member for environment, said: “Portslade Old Village is a hidden gem which we want to protect and conserve for generations to come.
“The council’s conservation team works hard to make sure that historic areas around the city are carefully looked after while listening to local groups and residents on what we should include.”
According to the council, Brighton and Hove has 34 conservation areas, each providing a unique record of the architectural and historic features across the city.
The effect on conservation areas is taken into account when the council considers new planning applications.
The review will be discussed at the forthcoming environment cabinet member meeting at Hove Town Hall tomorrow at 4pm.
