The local picture in Stevenage
Daylight is one of the first things Stevenage Borough Council will check on a garden house. At midday on 21 March the sun in Stevenage stands roughly 38° above the horizon, so an eaves line about 5 m high casts a shadow of around 6.4 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 Stevenage
From appraisal to a decision from Stevenage Borough Council, each step in Stevenage is agreed before it starts. After the site visit we quote for survey and design; after design we prepare the application; after permission we deal with conditions and technical approvals and give you a written build quote. Each stage is a separate decision for you, with its cost set out first.
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
- A build next door means months of noise, deliveries and contractors near your home; good planning reduces the disruption but doesn’t remove it.
- 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.
Stevenage: questions to ask
How long does planning take for a new home in a Stevenage 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.
Do new homes in Stevenage 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.
How close can a new house be to my own in Stevenage?
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 Stevenage 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 garden in Stevenage and keep the land?
Yes. On our design and build route you remain the owner while we design the home, apply to Stevenage 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.
