Before you decide in Carterton
Daylight is one of the first things West Oxfordshire District Council will check on a garden house. At midday on 21 March the sun in Carterton stands roughly 38° above the horizon, so an eaves line about 5 m high casts a shadow of around 6.3 m. On 21 December the sun is only about 15° up and shadows stretch far longer.
That’s why the gap between your house and the new one, and the height of the new roof, are set by measurement rather than guesswork. A lower eaves line, a hipped roof or a single-storey section can make a real difference to the gardens either side.
What happens next in Carterton
If your Carterton 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
- You fund the build and carry the cost risk; ground conditions, sewer diversions or supply upgrades found later can move the price.
- 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.
Questions about garden plots in Carterton
Can I build a house in my Carterton 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.
Will I pay Community Infrastructure Levy on a new home in Carterton?
Only if West Oxfordshire District 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.
How close can a new house be to my own in Carterton?
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 West Oxfordshire District Council decides. Window positions, ground levels, roof shape and screening all affect what is acceptable, which is why we survey before we design.
How long does planning take for a new home in a Carterton garden?
The statutory period for deciding a minor application, such as a single new home, is 8 weeks from the date the council receives a valid application, in both England and Wales. In practice many applications take longer, and the council may ask you to agree an extension in writing. Surveys and design before submission add time, and conditions may need approving afterwards.
