Land by postcode · KT area · New Malden
New Malden covers the KT3 postcode district, in Greater London. Planning applications here are decided mostly by the Kingston upon Thames planning authority, with Merton covering the rest. Below: what homes sold for, which planning controls apply, and what that means before you sell or develop a plot in New Malden.
Residential sales recorded by HM Land Registry between 2024-08 and 2026-07 across the KT3 district. This is market context for the town, not a land valuation: what a plot is worth depends on what can be built on it, which these figures do not show.

7 separate directions recorded, each removing particular permitted development rights within a defined area. The largest named one is the New Malden.
No postcodes in KT3 fall inside: Green Belt, National Landscape (AONB), National Park.
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 New Malden. 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 town-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.

It depends on where the plot sits, not on the town average. Across New Malden, 0% of postcodes are in the Green Belt and 2% 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.
Often, yes. 7% of postcodes in New Malden are under an Article 4 direction (7 separate directions), which withdraws particular permitted development rights, so an outbuilding, extension or change of use that is automatic elsewhere needs an application there. Outside those areas, permitted development applies to houses and their gardens but not to agricultural land or paddocks, where a new building or a new use normally needs 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 New Malden the median sale is £645,000, and only 8% 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 town 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 New Malden would be measured against a £645,000 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.
