Build a home for family in your garden in Lewisham

Two households, one plot: that’s the idea behind a family home in a Lewisham 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 Lewisham and the surrounding area, and each project begins with a free plot appraisal that weighs an annexe against a separate home for your family.

The local picture in Lewisham

Access usually decides what a Lewisham garden can take. An annexe can often share your drive because it is used with the house, but a separate home needs an access the London Borough of Lewisham will accept for a dwelling in its own right, with room for cars, bin collection and emergency vehicles. We cover homes in Lewisham and around Southwark, Greenwich and Lambeth, 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.

Noon sun in Lewisham on 21 March sits about 39° above the horizon, so a typical two-storey eaves line (about 5 m) throws a shadow of roughly 6.3 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.

How we’d take it forward in Lewisham

Here’s what happens next for a family home in Lewisham. 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 the London Borough of Lewisham.

  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

  • An annexe tied by planning condition usually can’t be sold or let separately, which limits flexibility later.
  • Planning is the council’s decision, and an annexe is not a way round the rules that apply to a new house.
  • 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 Lewisham

Is CIL payable on a family home in Lewisham?

Only if the London Borough of Lewisham 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.

How long will building work disrupt my home in Lewisham?

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 Lewisham?

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.

Can you design a home in Lewisham 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 the London Borough of Lewisham 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.
