Before you start in Hertfordshire
Drainage and wildlife often shape garden plots in Hertfordshire more than owners expect. A new home needs somewhere for rainwater and foul water to go, and you will need a drainage plan the council will want to see. Mature gardens can matter for wildlife, so expect biodiversity net gain rules to come into the design, along with tree surveys where large trees stand near the proposed home or drive. Public sewers crossing the garden may need a build-over agreement with the water company. None of this is a reason to give up, but it is a reason to survey before designing.
Planning authorities covering Hertfordshire include Broxbourne Borough Council, Dacorum Borough Council, East Hertfordshire District Council, Hertsmere Borough Council, North Hertfordshire District Council, St Albans City and District Council, Stevenage Borough Council, Three Rivers District Council, Watford Borough Council, Welwyn Hatfield Borough Council.
How it works
Free plot appraisal
We look at your garden using maps, the title plan and the planning history around you, then talk it through with you. If it looks workable we arrange a site visit. There’s no cost and no obligation.
Measure and test the layout
We check depth, the width of the way in, levels, trees, drains and what lies behind, then sketch what could realistically fit: one home, two, or nothing worth pursuing, before anyone pays for an application.
Choose your route
You decide whether to sell the plot outright, sell subject to planning, grant an option, team up with neighbours, or keep the land and have us design, get planning for and build a home on it.
Planning application
We prepare the drawings and reports, usually take pre-application advice, and submit. The council consults neighbours and decides. Small schemes often take a few months from submission, longer if surveys or amendments are needed.
Sale or build
If you sell, your solicitor handles the transfer of part and your lender’s release of the plot. If you build, we give a written quote after design and survey, then build and hand over the new home.

Questions about large rear gardens in Hertfordshire
Do you look at large rear gardens in Hertfordshire?
Yes. We cover the whole of Hertfordshire, as part of our coverage across England and Wales. Send us your address and a few details about your garden, and we’ll carry out a free desktop appraisal before suggesting a site visit.
Which councils decide garden plot applications in Hertfordshire?
Applications go to the local planning authority for your address. Across Hertfordshire, the authorities include Broxbourne Borough Council, Dacorum Borough Council, East Hertfordshire District Council, Hertsmere Borough Council, North Hertfordshire District Council and other councils. Each works to its own development plan and design guidance, so the tests for a rear garden home can differ from one council to the next. We check the right ones for your plot.
Is planning policy for back gardens the same across Hertfordshire?
No. National policy, the NPPF, applies everywhere, but each council adds its own plan and design guidance. Separation distances, garden sizes and parking standards can all differ. That’s why we never quote one rule for a whole county and always check the policies for your address.
How much is a garden plot in Hertfordshire worth?
It depends on location, size, access, title and, above all, planning. Two similar gardens in the same street can be worth very different amounts if one has easy access and the other doesn’t. We don’t quote figures before we’ve looked at a plot properly; the free appraisal is the way to find out.
