Sell an infill plot or gap site in Seaham

For owners of infill plots in and around Seaham, we offer four ways to sell, from a clean outright purchase to deals that pay more once planning is granted.

If you own an overgrown gap between houses, it may be worth much more as a plot than as a garden or yard.

  • Free appraisal and written offer
  • No commission: we're the buyer
  • No pressure to decide

Land we're keen to see around Seaham

  • Gaps in a continuous street frontage
  • Plots between two houses in a village or town
  • Former garages, workshops or yards in a street
  • Overgrown plots with a pavement frontage

Gap sites in villages and towns often have a clear case for a new home, because they complete a street rather than extend it.

What affects the price

Neighbours

Windows and gardens next door limit the size and position of the house.

Services

Infill sites usually have services close by, which helps value.

Heritage

Listed neighbours or conservation areas mean careful design.

Local values

What new homes sell for in the street sets the ceiling.

Four routes to a sale

Outright purchase

Simple where permission already exists.

Subject-to-planning sale

The usual route for unconsented gap sites.

Option agreements

Seldom needed for single infill plots.

Joint ventures

Possible for a pair of homes if you'd like a share.

How a sale works

  1. Send us the address

    A postcode, a plan or a what3words location is enough to start.

  2. We check it properly

    Title, planning history, access, flood maps and local policy.

  3. We put an offer in writing

    It shows how we got there. There's no obligation to accept.

  4. The legal work

    Your solicitor and ours handle the contract through to completion.

What England's rules mean for your land

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.

Heritage

Listed buildings and conservation areas are managed with Historic England and the council's conservation team.

When the land isn't straightforward

The plot is in a conservation area

Good design is essential in conservation areas. We'll design to the street.

Part of the gap belongs to a neighbour

Combining land can make a better plot. We can approach the neighbour with you.

Useful to send us

  • A rough size, in acres or hectares
  • Any planning applications or letters
  • Details of any tenants or grazing agreements
  • Photos of the land and its access

What people ask us about infill plots

Is infill easier to get permission for?

Often, because it continues the existing street pattern. Policy varies by council, especially in villages.

How wide does an infill plot need to be?

There's no fixed width. It depends on the house type, the street and whether parking is needed at the front.

Will you buy a gap site with a derelict garage on it?

Yes. We'll allow for demolition and any clean-up.
