Sell a small development site in Isleworth

If you own land around Isleworth and want a straight answer about it, we'll tell you whether we can buy it, on what terms, and what the offer is based on.

A small site is a piece of land that could take a handful of homes, typically up to around nine. National housebuilders often overlook small sites, which is where a regional builder buying direct can offer a better route to sale.

What makes small development sites near Isleworth worth an offer

  • Sites for two to around nine homes
  • Old yards, depots and lock-up sites
  • Land within a settlement boundary
  • Small sites in villages where policy supports limited growth

A corner of land, an old yard or a large garden can make a small site for a few homes. We buy them, and our aim is to take them through planning to new homes.

What affects the price

Number of homes

Each additional home a site can take adds value, if the layout works.

Trees and boundaries

Mature trees and hedges on small sites have a big effect on layout.

Drainage

Sustainable drainage must fit within the site.

Build costs

Small sites cost more per home to build, which the land price reflects.

Four routes to a sale

Outright purchase

Simple where permission exists or you need certainty now.

Subject-to-planning sale

The most common route for small unconsented sites.

Option agreements

Useful if land needs assembling from more than one owner.

Joint ventures

Can suit owners who'd like to share in the homes' sale value.

  3. You get a written offer

    With the main figures behind it, so your adviser can check it.

  4. Solicitors complete the sale

    Exchange and complete, or exchange now and complete when planning is granted.

Rules that apply in England

Planning framework

Planning decisions in England follow the National Planning Policy Framework, revised in August 2026, and the local plan, prepared by the council or, in a national park, the park authority. Plans are reviewed periodically, which is when new housing sites are usually allocated.

Biodiversity net gain

Under the Environment Act 2021, most developments in England must deliver at least a 10% gain in biodiversity. Since 6 August 2026, sites of 0.2 hectares or less are exempt unless priority habitat is affected.

Section 106 and CIL

Larger schemes often need a Section 106 agreement for affordable housing or contributions, and councils that have adopted the Community Infrastructure Levy charge it per square metre of new floorspace.

Common problems, and how we handle them

The site is an awkward shape

Odd shapes often still work for a short terrace or a pair of homes. We test layouts before offering.

The access is tight

We check whether it can serve the number of homes proposed.

Useful to send us

  • The address or postcode
  • Your title number, if you know it
  • Any planning applications or letters
  • Photos of the land and its access

Common questions

What is a small site?

Usually a site for fewer than ten homes. Definitions vary, but these are the sites larger builders often pass over.

Will you buy a site that needs demolition?

Yes. We price in demolition and any contamination clean-up.

Will you build the homes yourselves?

That's the aim of the land-to-homes work we're setting out to do: buying the land, getting permission and building the homes.
