How it plays out in Worthing
Wherever your house sits across BN11, BN12, BN13 and BN14, a new home behind it needs water, power and two kinds of drainage — one for waste, one for rain. We contact the utility providers early, because a long cable run, a sewer at the wrong depth or a public pipe under the lawn can change both the layout and the cost.
Rain from the new roof and drive has to be dealt with on site, and Worthing Borough Council will want to see how. Where a public sewer crosses your garden, the water company may also need a build-over agreement before work starts, so we check sewer records at appraisal stage.
How we’d take it forward in Worthing
Once you ask for an appraisal of your Worthing garden, we start with the paperwork: the title plan, any covenants, flood maps, tree and conservation designations, and planning decisions on nearby plots. A short call follows, then a site visit if the plot passes the desk check. You get our straight view of what’s realistic and what happens next, with no obligation to go further.
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.
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.
Worth checking early
- A build next door means months of noise, deliveries and contractors near your home; good planning reduces the disruption but doesn’t remove it.
- Building and selling a new home can change your tax position compared with selling only your house; take advice from a tax adviser first.
- Your own garden gets smaller and the new home will be visible from your house, so screening and separation matter for both homes.
Your questions, answered for Worthing
Do new homes in Worthing need a structural warranty?
If the house will ever be sold or mortgaged, in practice yes. Mortgage lenders usually expect a 10-year structural warranty on a new home, though some accept an architect’s or surveyor’s certificate, and a warranty provider inspects the work at stages during the build, so it has to be in place before construction starts. Building control approval is separate and also required; a buyer’s solicitor will ask for both.
Can I build a house in my garden in Worthing and keep the land?
Yes. On our design and build route you remain the owner while we design the home, apply to Worthing Borough Council for planning, deal with Building Regulations and build it. The finished house can be sold, let or kept for family. Whether your plot can take a house depends on access, space, neighbours and local policy, and the decision rests with the council.
Who decides planning for a garden house in Worthing?
Worthing Borough Council decides applications for addresses in Worthing, using the council’s Local Plan, national policy and its own design guidance. Neighbours and consultees such as highways officers can comment, and the decision is made by the council’s planning officers or, where the rules allow, its planning committee. Pre-application advice from the council can help test a scheme before the formal application is submitted.
Will I pay Community Infrastructure Levy on a new home in Worthing?
Only if Worthing Borough Council has adopted a Community Infrastructure Levy charging schedule; not every council has. Where it applies, it can be charged on a new home of any size. A self-build exemption exists for people building a home to live in, but it must be claimed before work starts, so we check the position at design stage.
