Build a new home in your garden in St Helens

Our garden design and build service is for St Helens owners who want to keep their land and have a new home built on it, managed from the first appraisal to handover. We cover St Helens and the places around it, and manage every stage for you.

The order of work is clear. Appraisal and survey come first, then design and the planning application, then Building Regulations, the warranty, utility applications and a written quote. Only then does construction start, in stages with inspections, ending with a handover pack you can pass to a buyer, tenant or family member.

What shapes a plot in St Helens

Wherever your house sits across L35, WA9, WA10 and WA11, 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 St Helens 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.

Noon sun in St Helens on 21 March sits about 37° above the horizon, so a typical two-storey eaves line (about 5 m) throws a shadow of roughly 6.7 m. In December the sun is only about 13° up and shadows stretch much further. Drawn for a garden facing north, where it matters most.

What happens next in St Helens

From appraisal to a decision from St Helens Borough Council, each step in St Helens 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.

  1. 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.

  2. 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.

  3. 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.

  4. 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

  • Your own garden gets smaller and the new home will be visible from your house, so screening and separation matter for both homes.
  • Building and selling a new home can change your tax position compared with selling only your house; take advice from a tax adviser first.
  • 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 St Helens

Do new homes in St Helens 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.

Do you visit gardens in St Helens before giving advice?

We start with a desk review of the title plan, access, constraints and planning policy, then talk the plot through with you. If it looks viable, we arrange a site visit to see the access, levels, trees and neighbouring windows for ourselves. The appraisal is free and carries no obligation.

Who decides planning for a garden house in St Helens?

St Helens Borough Council decides applications for addresses in St Helens, 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.

How long does planning take for a new home in a St Helens 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.
