Halstead Conservation Area covers 3.5 hectares and contains 6 listed buildings together with listed flint boundary walls. It was designated in 1973 and has not been reappraised since then. Outside the conservation area, but still within the confines of the village there are a further 9 listed buildings.
The village nestles in woodlands on top of the North Downs and within the Special Landscape Area.
The conservation area is centred around the old core of the village extending along Church Road and encompassing the main road junction. The Parish Church is located at the far end of Church Road and thus falls outside the boundaries of the conservation area.
The conservation area comprises mainly residential properties with some dwellings converted into commercial premises. The dwellings are generally two storeys in height with the exception of the Village House, which is significantly larger in terms of scale and mass than any other building.
The local use of flint is evident in the boundary walls that segregate the properties and the elevations to the cottages adjacent to Church Road junction.
