What to know in Hertfordshire
Surface water is a design question on every garden build in Hertfordshire, not an afterthought. A new roof and drive send rain somewhere, so the scheme will need a drainage plan the council will want to see. Foul drainage raises a different issue: the new home must connect to a sewer, and where a public sewer crosses the plot, the water company may need a build-over agreement. We check sewer records and ground levels at appraisal, because a sewer that sits too high or in the wrong place can move the house.
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 check the title plan, access, constraints and planning policy from our desk, talk the plot through with you, and visit if it looks viable. There’s no cost and no obligation.
Survey and design
A measured survey records levels, boundaries, trees and neighbouring windows. We then design a layout and house that suit the plot, the street and your budget, and decide whether pre-application advice is worth seeking.
Planning and approvals
We submit the planning application and manage it to a decision, then deal with conditions, Building Regulations approval, the structural warranty, any build-over agreement and the new utility connections.
Written quote and build
Once design and survey are complete you get a written quote. The build runs in stages — access and groundworks, foundations, frame and roof, fit-out and external works — with inspections at each key point.
Handover
You receive the completion certificate, warranty documents, Energy Performance Certificate, manuals and utility details, so the new home is ready to move into, let or put on the market.

Questions about build in your garden in Hertfordshire
What does a garden design and build cost in the Hertfordshire area?
There’s no standard figure, because cost depends on access, foundations, services, specification and size rather than on the county. Guide price ranges are on our prices page and are guides only. You receive a written quote after design and survey, with fees, warranty, connections and any Community Infrastructure Levy listed separately.
How is rainwater dealt with in Hertfordshire garden plots?
Rain from the new roof and drive must be managed on site, and for a new home that usually means a drainage plan the council will want to see. Soakaways, permeable paving, rain gardens or a controlled outflow are the usual options, depending on ground conditions and flood risk. We look at levels and soil at survey stage so the drainage design fits the plot.
Is your plot appraisal free for Hertfordshire homeowners?
Yes, and there’s no obligation. It begins with a review of your title, access, constraints and the relevant policies, followed by a conversation about what you want from the land. If the plot looks viable we arrange a site visit, and you then decide whether to move on to survey and design.
Do I need my own solicitor to sell a plot in Hertfordshire?
Yes, always. Your solicitor checks the contract, deals with the transfer of part at HM Land Registry and asks your mortgage lender to release the plot if the house is mortgaged. On option and promotion agreements we cover your reasonable legal fees, with the cap agreed in heads of terms before work starts.
