Build a home for family in your garden in Biggleswade

For grown-up children in Biggleswade, the step to a first home can be a long one. If your garden is big enough, a small separate house on part of it could become theirs: with its own planning permission and title, it can be mortgaged in their name and sold when they move on.

That asks more of the plot than an annexe does, including its own garden, parking and an access Central Bedfordshire Council will accept. We look at all of that in a free plot appraisal, then design and build the home if the scheme stacks up and you want to go ahead.

What the council will look at in Biggleswade

How the two households will live together shapes the planning case as much as the drawings do. If your parent will eat with you, share the garden and rely on you day to day, an annexe is the natural fit, and that is what Central Bedfordshire Council will expect the application to describe. If your son or daughter will run their own home, pay their own bills and perhaps sell up one day, it is a separate dwelling and will be assessed against the council’s Local Plan as a new house. For a family in SG18, we help set that out clearly from the start.

Noon sun in Biggleswade 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 14° up and shadows stretch much further. Drawn for a garden facing north, where it matters most.

How we’d take it forward in Biggleswade

From first call to keys, a family home in Biggleswade follows a clear order. Free appraisal and site visit; measured survey and design around the person moving in; a planning application to Central Bedfordshire Council; approval under the Building Regulations and any CIL exemption claimed before work starts; then the build, with you living next door throughout. You receive a written quote after design and survey, and we keep the household updated at each stage.

  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. 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.

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.
  • CIL exemptions are lost if work starts before the claim is made, and can be withdrawn if the home is sold or let within three years.

Questions about garden plots in Biggleswade

How long will building work disrupt my home in Biggleswade?

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.

Who owns an annexe built in my Biggleswade garden?

You do. An annexe stays on the title of your house and usually carries a planning condition tying it to the main home, so it can’t be transferred to the relative living in it. If a family member is paying towards it, record what they’ve put in and what happens on a sale in a written agreement drawn up by a solicitor.

Can I build a separate house in my Biggleswade garden for my son or daughter?

Possibly, if the plot can work as a home in its own right. Central Bedfordshire Council will look at access, parking, garden space for both houses, privacy and the character of the street, as it would for any new house. If permission is granted, the plot can be transferred to your child with its own title, with your lender’s consent if the house is mortgaged.

Can you design a home in Biggleswade 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 Central Bedfordshire 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.
