Sell an Infill Plot in Wallington
An infill plot in Wallington 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 Wallington
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.
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.
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.
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 in Wallington: the English rules
If your land near Wallington lies in the Green Belt, national policy still protects it, but England's planning framework now recognises grey belt: Green Belt land that is previously developed or does not strongly contribute to certain Green Belt purposes. Where there is evidenced unmet need and the location is sustainable, grey belt housing can be acceptable, with major schemes meeting the Golden Rules on affordable housing, infrastructure and green space. Planning is never guaranteed, so we check policy, access and constraints first.
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.

Questions about Sell an Infill Plot in Wallington
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 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.
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.
