Build a home for family in your garden in Hitchin

The first question for any family in Hitchin 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. North Hertfordshire District 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.

Hitchin: light, access and policy

A measured survey is where a family home in Hitchin stops being an idea and becomes a plan. We record boundaries, levels, trees, drains and the windows of your house and the houses next door, then test where the new building can sit. With the spring equinox sun standing near 38° at midday here, a 5 m eaves line throws a noon shadow close to 6.4 m; drawing that onto the survey shows which positions keep light in the main rooms of both homes. North Hertfordshire District Council will expect to see the same evidence with the application.

Noon sun in Hitchin on 21 March sits about 38° above the horizon, so a typical two-storey eaves line (about 5 m) throws a shadow of roughly 6.4 m. In December the sun is only about 15° up and shadows stretch much further. Drawn for a garden facing north, where it matters most.

What happens next in Hitchin

Here’s what happens next for a family home in Hitchin. You tell us about your plot and who the home is for, and we carry out a free desktop appraisal of access, space and the planning context. If it looks viable we visit, then set out the annexe and separate-home options. With your go-ahead we survey, design and give you a written quote, then prepare the application for North Hertfordshire District Council.

  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. Planning and approvals

    We prepare and submit the planning application and manage it with the council, which makes the decision. Before work starts, approval under the Building Regulations is in place and any CIL exemption has been claimed.

  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

  • Planning is the council’s decision, and an annexe is not a way round the rules that apply to a new house.
  • Family plans change: agree ownership, costs and what happens if circumstances change in writing, with a solicitor.
  • A separate home needs its own garden, parking, bins and access, so it needs more land than an annexe.

Your questions, answered for Hitchin

How much garden do I need for a family home in Hitchin?

There’s no fixed figure. A single-storey annexe close to the house can work on a smaller plot than a separate dwelling, which needs its own garden, parking and access. What matters is whether North Hertfordshire District Council can be satisfied on privacy, daylight and the space left for both homes. The free appraisal gives you a first view based on your plot’s actual shape and access.

Can I reclaim VAT on a family annexe in Hitchin?

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.

Will an annexe in Hitchin put up my council tax?

It might. Annexes can be banded separately, but exemptions exist for annexes lived in by certain dependent relatives, and in some cases a discount applies where family live there or the annexe is used as part of the main home. Who qualifies depends on the relative’s circumstances and how the annexe is used. North Hertfordshire District Council’s council tax team can tell you how the rules apply to your household.

Can you design a home in Hitchin 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 North Hertfordshire District 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.
