Build a home for family in your garden in Runcorn

The first question for any family in Runcorn thinking about building in the garden is usually this: annexe or proper house? The answer turns on the person moving in, how long they’re likely to stay, and whether you might ever want to sell or let the building on its own.

An annexe is used with your home and usually tied to it by condition. A separate dwelling stands alone, with its own permission and potentially its own title. Halton Borough Council assesses them on different terms, and council tax, CIL and VAT rules split along the same line. Our free plot appraisal sets out both, so you can decide with your family and your advisers.

How it plays out in Runcorn

Access usually decides what a Runcorn garden can take. An annexe can often share your drive because it is used with the house, but a separate home needs an access Halton Borough Council will accept for a dwelling in its own right, with room for cars, bin collection and emergency vehicles. We cover homes in Runcorn and around Widnes, Halewood and Huyton, and on every plot we measure the drive width, the view along the road where the access joins it, and how far bins would need to travel, before anyone draws a plan.

From first call to decision

Getting started in Runcorn costs nothing. Send us a few photos of your garden and the way in, or simply call, and we’ll look at the plot from the desk and talk through your family’s plans. If there’s a realistic scheme, we arrange a site visit. Survey and design are quoted in writing before you commit, and the build price follows once the design is settled.

  1. Free plot appraisal

    We look at your plot, access and the planning picture from the desk, talk through who will live in the new home, and visit if it looks viable. There’s no cost and no obligation.

  2. Annexe or separate home

    We set out both routes for your plot, covering what each means for planning, ownership, council tax, CIL and VAT, so you can decide with your family and advisers before design starts.

  3. Survey and design

    A measured survey, then a design built around the person moving in: step-free routes, a ground-floor bedroom if needed and privacy for both households. You get a written quote after design and survey.

  4. Build and handover

    We build while you carry on living next door, with access, deliveries and working hours agreed up front. At handover you get the completion certificate and the paperwork you’ll need for council tax, lenders and any VAT claim.

Worth checking early

  • A separate home needs its own garden, parking, bins and access, so it needs more land than an annexe.
  • An annexe tied by planning condition usually can’t be sold or let separately, which limits flexibility later.
  • VAT savings available on a separate dwelling often don’t apply to an annexe; take advice from a tax adviser before choosing.

Questions about garden plots in Runcorn

How long will building work disrupt my home in Runcorn?

A single garden home usually takes several months on site, with the noisiest work, such as groundworks, drainage and heavy deliveries, concentrated near the start. We agree working hours, access and parking with you up front, and with the people next door where it affects them, so your household knows what each week will look like.

Can I reclaim VAT on a family annexe in Runcorn?

Often not. HMRC’s guidance gives an annexe that can’t be used or sold separately from the main house as an example of work that can’t be zero-rated, and the DIY housebuilders refund scheme asks the same question. A separate dwelling is usually treated differently. Take advice from a tax adviser before you settle the planning route, because the wording of the permission matters.

Is CIL payable on a family home in Runcorn?

Only if Halton Borough Council has adopted the Community Infrastructure Levy, which its website will confirm, and we check it for you during the appraisal. Where it applies, self-build and residential annexe exemptions exist, but both must be claimed before work starts and can be withdrawn if the home is sold or let within three years of completion.

Can you design a home in Runcorn for a relative who uses a wheelchair?

Yes. The design can include a level approach and threshold, turning space in each room, a wet room, wider doors and worktops at a usable height. Where Halton Borough Council requires a particular access standard through planning, the design meets it; otherwise it’s your choice how far to go. Input from your relative’s occupational therapist is well worth having.
