Sell an Infill Plot in West Sussex
An infill plot in West Sussex 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.

Why work with Land to Homes in West Sussex
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.
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.
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.
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.
The English system, as it applies in West Sussex
In England, most planning applications for new homes in West Sussex are decided by the local planning authority, usually the council, using its Local Plan and the National Planning Policy Framework. Many landowners sell without planning, either outright or through an option or promotion agreement that funds the application first. Land to Homes offers a free site appraisal, pays your reasonable legal fees on option and promotion agreements, and can buy suitable sites directly, subject to survey, title and contract.
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 West Sussex
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.
Can I sell the side garden of my end-of-terrace house?
Often, yes, where the side garden is wide enough for a new home that continues the terrace or stands as a separate detached house. Consider the impact on your own home, parking and garden, and whether your mortgage lender will agree to release the land.
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.
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.
Do you buy land in West Sussex?
Yes. Land to Homes looks at land across West Sussex, including Worthing, Crawley and Burgess Hill. Every enquiry starts with a free site appraisal, and on option and promotion agreements we pay your reasonable legal fees.
