Sell an Infill Plot in Hertfordshire
Selling infill land in Hertfordshire turns on three questions: does the gap fit the pattern of the street, are services and access available, and would a new home affect neighbours' light or privacy? Land to Homes checks each one, explains the likely scale of scheme, and puts any offer or terms in writing before you commit.

In and around Hertfordshire, the land we appraise ranges from large and long rear gardens to fields put forward or allocated in the local plan, including land that already has planning permission. As Hertfordshire is in England, applications are judged against the National Planning Policy Framework, and the buyer of land pays Stamp Duty Land Tax (SDLT).

Our approach in Hertfordshire
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.
Small plots still count
Many single-plot sites are viable. We look at what could fit, from one detached house to a short terrace, rather than dismissing a site because of its size.
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.
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.
How the rules work in Hertfordshire
If your land near Hertfordshire 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.

Your questions answered for Hertfordshire
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.
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.
What is an infill plot?
An infill plot is a gap within an existing line of buildings, such as a space between two houses or at the end of a terrace, where a new home would continue the street rather than extend into open land. Exact definitions vary between councils, and rural policies often define infill more narrowly.
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.
