Older buildings are the important to our heritage and the built environment. Accordingly, some buildings in the parish are protected with listed building status which limits the activities that can be undertaken to them without permission.
Anyone who wants to demolish a Listed Building, or to alter or extend one in any way that affects its character, must obtain Listed Building Consent from the Local Planning Authority. This is in addition to the normal planning permission process.
There is 1 grade II* and 5 grade II Listed Buildings in the parish.
