Side return extension in Gillingham

Side return extension in Gillingham: infilling the narrow passage beside a Victorian or Edwardian back addition. We measure the house, show you what the rules allow, price it in writing and build it.

Gillingham and its postcode districts ME7 and ME8 are part of our Kent coverage. In Gillingham we check the boundary line and the neighbour's gutter before drawing a side return, because a few centimetres decide whether the wall goes on or beside the boundary.

Do you need planning permission for a side return extension in Gillingham?

Whether your side return extension in Gillingham needs a planning application depends on its size, your house and any local restrictions.

In England the side part of a side return or wraparound must meet the side-extension rules (one storey, under 4 metres high, no more than half the width of the original house), and those rights do not apply on designated land. Because a wraparound combines a side and a rear extension, many need householder planning permission.

Because rear extensions often sit on or near the boundary, the Party Wall etc. Act 1996 usually applies in England. Notices go out one or two months before work depending on the type of work, and a surveyor's award is only needed if a neighbour does not consent.

Conservation areas, National Parks, National Landscapes and the Broads restrict permitted development, and listed buildings always need listed building consent. We check your house's planning history and any conservation area before drawing, so the route is clear before you spend on plans.

What are homes in Gillingham like to extend?

Gillingham has a mix of Victorian terraces near the centre and larger Edwardian and inter-war houses further out. Clay soils across much of the South East mean deeper foundations near trees, which we plan for at the survey.

How a side return extension in Gillingham comes together

  1. Look round and measure

    A free visit to see the back of the house, measure it, check the drains and boundaries and hear what you need.

  2. Options and costs

    We draw layout options and price each one, so the budget shapes the design rather than surprising you later.

  3. Planning and regulations

    We take the design through the right planning route, then produce the construction drawings and engineer's calculations for building control.

  4. Build and sign-off

    We build to the approved drawings with regular updates, then hand over the building control completion certificate and any guarantees from suppliers.

FAQ

Side return extension questions in Gillingham

How much does a side return extension cost in Gillingham?

As a guide, £2,580–£4,260 per square metre including VAT for a standard specification. For example, 2 m wide × 6 m deep (12 m²): about £31,000–£51,000 at that rate. Your written price follows the survey.

Do you handle building control in Gillingham?

Yes. We apply to the council or a registered building control approver and hand over the completion certificate.

Glass roof or solid roof with rooflights?

A glass roof gives the most light; a solid roof with long rooflights is warmer and quieter in rain. Both work.

Do I need a party wall agreement?

In England, usually yes if the extension is on or near a shared boundary or the foundations are close to a neighbour's building. We serve the notices.

Can I live at home while the extension is built?

Usually yes. Most of the work is outside until the back wall is opened near the end, and that stage is screened off.

Can you match the brick or stone on my Gillingham house?

We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
