Build a home for family in your garden in Tower Hamlets

The first question for any family in Tower Hamlets 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. The London Borough of Tower Hamlets 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.

What the council will look at in Tower Hamlets

People living next door are consulted on every planning application, and across E1, E1W, E3 and E14 that applies to a family annexe just as much as to a new house. Their privacy, outlook and light carry real weight with the London Borough of Tower Hamlets. A design that keeps upper windows away from adjoining gardens, uses obscure glazing where it has to, and leaves a planted margin along the boundary gives the council fewer reasons to refuse. A quiet word with the people either side before the application goes in is often worthwhile too.

From first call to decision

From first call to keys, a family home in Tower Hamlets follows a clear order. Free appraisal and site visit; measured survey and design around the person moving in; a planning application to the London Borough of Tower Hamlets; 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. 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.

  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.
  • VAT savings available on a separate dwelling often don’t apply to an annexe; take advice from a tax adviser before choosing.
  • 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 Tower Hamlets

How long will building work disrupt my home in Tower Hamlets?

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 you design a home in Tower Hamlets 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 Tower Hamlets 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.

Who owns an annexe built in my Tower Hamlets 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.

Is CIL payable on a family home in Tower Hamlets?

Only if the London Borough of Tower Hamlets 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.
