How conservation area status affects what you can do to your home in England — the permitted development rights it removes, the extra consents it adds, and how to check whether your property is in one.
Conservation areas are designated by local authorities right across England to protect the character of an area. Designation does not freeze a property, but it narrows permitted development rights and adds extra controls — particularly to anything visible from the street, to roofs, and to trees. This guide explains what actually changes.
These are the common features that keep a project on the simpler route.
These are the usual triggers that push a scheme beyond straightforward PD rights.
The tool is designed to answer the first question most homeowners have: is this worth pursuing, and what is most likely to block it?
CanUBuild checks whether your exact address falls within a conservation area using the national conservation-area dataset.
It combines that with listed status, Article 4 directions and tree preservation orders, so you see every overlapping control in one place.
You see decided applications nearby, so you can judge how your local planning authority applies conservation-area policy in practice.
It means some permitted development rights are restricted and extra controls apply, particularly to anything visible from the street, to roofs and to trees. Many projects are still possible, but more are likely to need planning permission.
Usually yes, but within tighter limits. Rear extensions that are not visible from the street are the most straightforward; roof changes and side extensions are more likely to need permission and a sympathetic design.
In a conservation area you generally must give the council advance notice before significant work to most trees, which lets them decide whether to protect the tree with an order.
Conservation areas are mapped by local authorities. An address-level check confirms whether your specific property is within one, along with any other designations.
Search for the address, choose your project type, and get a planning feasibility answer based on permitted development rules, constraints, and local precedent data.
