How we work in Seaham
We can buy the plot
Where a plot suits us, we can buy it ourselves, with or without planning, with no onward chain, subject to survey, title and contract. Any offer is set out in writing.
Self-builder or developer
Some infill plots suit individual self-builders, while others suit a developer building several homes. We explain who is likely to want your plot and what that means for the deal.
Street scene first
Councils look at the building line, roof heights, plot widths and materials along the street. A new home that follows that pattern has a much better chance of approval than one that ignores it.
Village infill policies
Some rural policies allow limited infilling within villages even where wider development is restricted. We check whether your plot falls within the exact wording of those rules.
Planning and land rules in Seaham
Land with no planning permission can still be sold. Around Seaham, the usual routes in England are a direct sale, an option agreement or a promotion agreement, where the planning work is funded for you and the land is sold once consent is granted. Outline planning permission settles the principle, with reserved matters approved later. Section 106 obligations, the Community Infrastructure Levy where charged and biodiversity net gain all affect what a site is worth, so independent advice matters.
In England, the NPPF supports small sites and treats limited infilling in villages as an exception within the Green Belt. Smaller schemes can test the principle of housing through Permission in Principle before detailed design. Party wall procedures apply where work affects a shared wall or boundary, and buyers pay Stamp Duty Land Tax.

Common questions in Seaham
What does a buyer check on a small infill site?
Title and boundaries, rights of way, the planning history of the plot, the location of sewers and water mains, trees, drainage, ground conditions, and whether the street has a pattern a new home can follow. Small issues matter more on small sites because they directly affect what can fit.
How small can a plot be for a new house?
There is no single minimum. It depends on the width of the frontage, the size of neighbouring plots, space standards for the new home, garden and parking requirements, and how the design fits the street. A narrow plot may still work for a terraced design that continues an existing row.
Should I sell an infill plot with or without planning?
Selling with permission usually achieves a higher price, but means paying for drawings, surveys and fees yourself and accepting the risk of refusal. Selling without planning is simpler and passes that risk to the buyer. A contract conditional on planning sits between the two and suits many small plots.
Do infill plots need biodiversity net gain?
In England, recent changes exempt many very small sites from biodiversity net gain, subject to conditions, and other exemptions may apply. Wales, Scotland and Northern Ireland take different approaches to biodiversity in planning. Check the current rules with your council or a planning consultant before you apply.
Is Seaham an area you cover for land?
Yes, we cover land in Seaham and elsewhere in County Durham, including Durham, Consett and Darlington. Where a site suits us we can buy it directly, or set up an option or promotion agreement. On promotion there is nothing to pay upfront.
