What the council will look at in Romsey
Wherever your house sits across SO51, 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 Test Valley 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 Romsey
Getting started in Romsey takes one step from you: send your address and a few photos of the garden, or call us. We check the title plan, access and planning constraints from our desk, then talk the plot through. If it looks viable we arrange a visit, discuss whether you want to sell, let or keep the new home, and set out the survey and design stage in writing before you commit.
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.
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.
Worth checking early
- Your own garden gets smaller and the new home will be visible from your house, so screening and separation matter for both homes.
- Planning can be refused, and money spent on surveys, design and the application isn’t recovered if it is — which is why we start with an appraisal.
- A build next door means months of noise, deliveries and contractors near your home; good planning reduces the disruption but doesn’t remove it.
Your questions, answered for Romsey
Do new homes in Romsey 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.
Who decides planning for a garden house in Romsey?
Test Valley Borough Council decides applications for addresses in Romsey, 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.
Can I build a house in my garden in Romsey and keep the land?
Yes. On our design and build route you remain the owner while we design the home, apply to Test Valley 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.
Can the new home in my Romsey garden connect to the main sewer?
Usually, yes, but the route and depth decide how easily. The new home needs its own foul connection, agreed with the water company, and gravity drainage is simplest where the sewer sits lower than the new floor. If it doesn’t, a pumped connection may be needed. Where a public sewer runs under your garden, a build-over agreement or diversion may also be required.
