Conservation areas

Planning Permission for ‘relevant demolition’ is required for most works for the demolition of all, or part of any building within a Conservation Area, where the building is over 115 cubic metres in volume (measured externally).

Demolition of boundary walls, fences or gates that are more than 1m high fronting onto a highway, public right of way or open space, or higher than two metres elsewhere also require permission for ‘relevant demolition’.  

It is a criminal offence to fail to obtain consent before undertaking such demolition work.  If you are in any doubt whether you require consent for works you should contact Planning Services at dcsubmissions@knowsley.gov.uk for advice. 

If the property to be demolished is also a Listed Building you would need to apply for Listed Building Consent only.  

Where the building or boundary feature makes a positive contribution to the conservation area, there is a general presumption in favour of retaining it.  If you wish to demolish a building, or part of a building, or boundary feature clear justification will be required. Proposals may need to be supported by a full structural survey.  

Any proposals for demolition should show what the proposals are for replacement features, and information on landscaping and surfacing where relevant. If the building or boundary wall in question makes no contribution to the special interest of the area, the granting of consent may be dependent on there being acceptable and timely plans for redevelopment.
