Land by postcode · CR area · CR4
What the open records say about the CR4 postcode district in Greater London: recent sales, planning designations and controls, and the council that decides applications. District-level facts to read before you sell or develop a plot in Mitcham.
Residential sales recorded by HM Land Registry between 2024-08 and 2026-07. This is market context for the district, not a land valuation: what a plot is worth depends on what can be built on it, which these figures do not show.

Mitcham Cricket Green · Wandle Valley
No postcodes in CR4 fall inside: Green Belt, National Landscape (AONB), National Park, Article 4 Direction area.
Flood zones, tree preservation orders, local plan allocations, settlement boundaries and non-designated heritage are not included here and are checked in a full assessment.
None of these designations covers more than a small share of postcodes in CR4. What can be built on a given plot is decided by the local plan, settlement boundaries and site-specific matters such as access, flood risk and neighbours, none of which this page measures.
These are district-level facts. The free assessment checks your actual boundary against the same registers and the local plan and tells you plainly what they mean for your plot.

Draw your boundary, tell us what you own, and an architect checks it against these registers and the local plan. Free, no obligation, and you get a straight written answer.
It depends on where the plot sits, not on the district average. In CR4, 0% of postcodes are in the Green Belt, 7% in a conservation area. Outside those designations the questions that decide it are whether the plot is inside or adjoining the settlement boundary in the local plan, whether it has its own road access, and what is next to it. A plot on the edge of a village or town with access has the best chance; an open field outside the settlement boundary rarely gets consent for housing whatever the market is doing.
No Article 4 direction is recorded for CR4, so houses keep their normal permitted development rights for outbuildings and extensions within the size limits. Those rights do not extend to agricultural land, paddocks or a change of use to residential, which normally need permission or prior approval.
Developers look at three things before they talk about price: whether the plot is outside the Green Belt and any National Landscape, whether it sits inside or beside the settlement boundary, and what finished homes sell for. In CR4 the median sale is £435,000, and only 0% of 2023–2024 sales were new-build homes, so builders have been quiet here. A single plot usually goes to a local builder or a self-builder; a site for five or more homes attracts regional housebuilders, normally through an option or a conditional contract rather than an outright purchase, so the price you see quoted is not the price you receive.
There is no district figure for land, because a plot's value comes from what can be built on it, not from where it is. As a guide, a serviced plot with consent for one house commonly sells for around a third of the finished house value, which in CR4 would be measured against a £435,000 median sale. The same plot without consent, or inside the Green Belt, is worth a small fraction of that, and a paddock with no realistic route to consent is worth agricultural or amenity value only. The free check tells you which of those your plot is before you talk to anyone about a price.
Three places: Merton's local plan and its policies map for the settlement boundary and allocations, the council's planning register for what has been approved or refused on neighbouring land, and planning.data.gov.uk for the national designations. That is an evening's work if you know what you are looking for. The alternative is to draw your boundary on this site: an architect checks it against the same records and writes back within 48 hours with a plain answer, free and without obligation.
