Will the council need to approve it?

In England a single-storey rear extension can usually go up to 3 m beyond the original rear wall of a semi-detached or terraced house, or 4 m on a detached house, without a planning application, provided it is no more than 4 m high, keeps eaves to 3 m within 2 m of a boundary and, with other buildings, covers no more than half the land around the original house. The larger home extension prior approval scheme raises those depths to 6 m and 8 m, with neighbours notified and a 42-day decision.

Before any drawing is finalised we check whether the house is listed, in a conservation area or subject to an Article 4 direction.

If the work involves a shared wall, building on the boundary, or digging foundations within 3 m (sometimes 6 m) of a neighbour's building, the Party Wall etc. Act 1996 applies and notice must be served before work starts: two months for work to a party wall, one month for new walls on the boundary and for excavations.

Building over or within 3 m of a public sewer needs the water company's consent, usually through a build-over agreement, before the foundations go in.

Applications are decided by the local planning authority (your district, borough or unitary council).

When a timber frame extension makes sense

  • Contemporary designs with timber or board cladding
  • Sites where weight or speed matters
  • Homeowners who want strong energy performance

Local to Gravesend

Site visits are available across Gravesend (DA10, DA11, DA12). The same team covers Strood (6 miles), Dartford (7 miles), Rochester (7 miles), Chatham (8 miles), all within easy reach.

Grays, in Essex, is roughly 3 miles from Gravesend and also on our list. In the South East, plenty of houses have already been extended once, which makes checking the remaining permitted development allowance an important early step.

How the project works

Site visits are free and there is no obligation. Where drawings are needed, the design stage is priced in writing before it starts.

  1. Free site visit

    It starts with a visit to your house to measure, check access and talk through ideas and budget.

  2. Design and approvals

    We produce the drawings and structural design, and manage the approvals so they are in place before work starts.

  3. Fixed written price

    You receive a written, itemised price and programme. Nothing starts until you are happy with it.

  4. Build and sign-off

    Our team builds the extension, keeps you updated weekly and finishes with building control sign-off.

Common questions in Gravesend

How long does a timber frame extension take to build in Gravesend?

On site, typically 8 to 14 weeks once approvals are in place. Before that, allow 4–12 weeks design and approvals.

Who do I contract with for a timber frame extension in Gravesend?

Your contract is with S&K Property Investments and Improvement Ltd, which designs and manages the project and the build teams who carry it out.

Can I see a price before committing to anything?

Yes. The guide prices on this page are adjusted for Gravesend, and the guide-price tool gives a range for your own size. After the survey you get a written price before anything is agreed.

Does a timber frame extension need planning permission?

The same planning rules apply as for any extension. If the cladding looks different from the house, permitted development’s matching-materials condition may mean an application is needed.

Is timber frame cheaper than brick?

It is similar overall. The frame can save time on site, but the cladding choice has a big effect on cost. Our guide range is about £1,960 to £3,810 per m² including VAT.
