Before you decide in Staines-upon-Thames
Wherever your house sits across TW18 and TW19, 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 Spelthorne 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.
What happens next in Staines-upon-Thames
If your Staines-upon-Thames plot already has planning permission, we begin by checking the approved drawings and conditions against the site. Some permissions need detailed design, discharge of conditions or a minor amendment before they can be built. We then prepare the technical drawings, arrange Building Regulations approval and the warranty, apply for utility connections and give you a written quote to build.
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.
Worth checking early
- 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.
- Your own garden gets smaller and the new home will be visible from your house, so screening and separation matter for both homes.
- 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 Staines-upon-Thames
How close can a new house be to my own in Staines-upon-Thames?
There’s no single national distance. Many councils use separation guides of around 21 metres between facing back windows and around 12 to 15 metres between a back window and a blank side wall, but the guidance used by Spelthorne Borough Council decides. Window positions, ground levels, roof shape and screening all affect what is acceptable, which is why we survey before we design.
Can I build a house in my Staines-upon-Thames garden and then sell it?
Yes. You keep the land while the home is built, then sell the finished house. Before building starts, the plot should be given its own title through a transfer of part at HM Land Registry, and if your house is mortgaged your lender must agree to release the plot. Selling a home you’ve built can change your tax position, so take advice from a tax adviser first.
Can I build a house in my garden in Staines-upon-Thames and keep the land?
Yes. On our design and build route you remain the owner while we design the home, apply to Spelthorne 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 Staines-upon-Thames 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.
