What we look for

In Hertfordshire we look for land in and around existing towns and villages, including sites that have been built on before.

There is no minimum or maximum size of land required.

Sites without planning

Land where nobody has applied yet, or where an application was refused.

Commercial freeholds

Offices, industrial units and shops that could become homes, or carry extra floors on the roof.

Unused buildings

Garages, yards and outbuildings sitting idle on a larger site.

Brownfield land

Vacant, derelict or previously developed land. Some Green Belt land now counts as grey belt.

Selling land in Hertfordshire: what to know

Much of south Hertfordshire is Green Belt, keeping open land between London and towns such as Watford, St Albans and Hatfield. Demand for homes in these commuter towns is strong, so land with a realistic route to planning is scarce and valuable.

National planning policy now recognises grey belt: land in the Green Belt that has been built on before, or that does not strongly serve the purposes of the Green Belt. Where a council cannot meet its housing need, some of this land can now be considered for homes, subject to conditions such as affordable housing and green space. Old yards, nurseries, farm buildings and edge-of-town plots are worth a fresh look.

In the towns, the usual opportunities apply: large rear gardens, infill plots, garage courts and commercial buildings that could be converted or replaced.

Two ways to sell

Option 1

Sell subject to planning

We agree a fair market price now, run the planning application ourselves, then complete the purchase once permission is granted.

Best if you want a clean sale and a known price.

Option 2

Joint venture

Your land goes into the scheme. We plan, build and sell it, and you share in the profit when the homes are sold.

Best if you want a bigger share of the upside.

Palmerston Crescent, Enfield: surplus TfL land secured through the Small Sites Small Builders programme
Case study

Trusted by TfL with its land

We were a development partner on one of the first sites TfL released through the Mayor of London's Small Sites Small Builders programme, and TfL has since trusted us with a second.

Poplar, Tower Hamlets: planning granted for 9 new homes over five storeys on a tight, constrained plot, and works on site have started. Palmerston Crescent, Enfield: around 70 new homes, now in planning. For TfL, that means surplus land turned into new homes, with us taking the schemes through planning.

Questions landowners ask

Do I need planning permission before I contact you?

No. Most of the sites we buy have no planning when we first see them. Getting planning permission is our job.

What size of site do you buy?

There is no minimum or maximum size of site. We work on everything from small infill plots to schemes of around 70 homes.

Where do you buy?

London and the Home Counties.

What about green belt land?

Building on green belt is tightly controlled, so it is rarely a fit. Send it anyway and we will give you our view.

Who pays the planning costs?

We do. On a subject-to-planning deal Kisiel pays for the architects, surveys, reports and the planning application. You pay nothing to get your site through planning.

What could your site be worth?
