Sell an Infill Plot in County Durham
An infill plot in County Durham is a gap in an otherwise built-up street or frontage, such as land between two houses, a side garden at the end of a terrace, or a cleared site in a row. Because it fills a gap rather than extending a settlement, it often has policy support, but design and neighbour impact are scrutinised closely.

What we offer in County Durham
Neighbours' light and privacy
Window positions, outlook and daylight to neighbouring homes are tested in planning. We look at how a design could protect them, because this often decides whether infill is approved.
Party walls and boundaries
Building on or near a shared boundary can trigger party wall procedures in England and Wales. Clear boundaries on the title plan help avoid disputes with neighbours later on.
Services and connections
Connecting water, sewers and power to a single plot can be costly where mains are not close by. We check where services run before estimating what the plot could support.
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.
Planning and land rules in County Durham
Selling development land in County Durham usually starts with heads of terms, a short written summary of price, conditions and fees, before solicitors draft the contract. In England the sale becomes binding on exchange of contracts and finishes on completion, with the title then registered at HM Land Registry. The buyer normally pays Stamp Duty Land Tax. On option and promotion agreements with Land to Homes, your reasonable legal fees are covered, with the amount agreed in the heads of terms.
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.

Your questions answered for County Durham
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.
Do my neighbours have a say if I sell an infill plot?
You do not need their permission to sell, but they will be notified when a planning application is made and can comment on it. Early, courteous contact often helps, especially if party walls, shared drives or boundary features such as hedges and fences are involved.
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.
