Build a home for family in your garden in Lancaster

Two households, one plot: that’s the idea behind a family home in a Lancaster garden. Done well, each has privacy and a front door, yet help is a few steps away. Done badly, it can strain relationships and leave a building nobody can use when circumstances change.

The difference lies mostly in the planning route and the layout. Backland Development is a new S&K Group brand offering design and build to homeowners in Lancaster and the surrounding area, and each project begins with a free plot appraisal that weighs an annexe against a separate home for your family.

What the council will look at in Lancaster

Lancaster City Council will judge a family home against the council’s Local Plan and any guidance it has adopted on garden development and annexes. Some councils spell out how closely an annexe must relate to the main house, such as sharing the drive, garden or parking, and what turns a building into a separate home instead. We read the current policies for your address before design starts, because a scheme drawn to suit the wrong test wastes time and money. Where the position is unclear, the council’s pre-application advice can be worth its fee.

What happens next in Lancaster

Here’s what happens next for a family home in Lancaster. 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 Lancaster City 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

  • 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.

Your questions, answered for Lancaster

Will an annexe in Lancaster 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. Lancaster City Council’s council tax team can tell you how the rules apply to your household.

Do I need planning permission for a granny annexe in Lancaster?

Yes, almost always for a detached annexe with its own kitchen, bathroom and bedroom. Lancaster City Council will treat it as accommodation linked to your home and will usually add a condition so it can’t be let or sold separately. A garden building used only as a home office or gym is a different matter, but sleeping and cooking take it beyond those allowances.

How long will building work disrupt my home in Lancaster?

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.

Is CIL payable on a family home in Lancaster?

Only if Lancaster City 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.
