Timber frame extensions for homes in Southport

A timber frame extension in Southport starts with the right design and the right approval route. We take care of both, then build it with our own project management.

Extensions in and around Southport

Across PR8, PR9, we can visit, measure and advise. The same team covers Formby (7 miles), Maghull (9 miles), Litherland (12 miles), Kirkby (12 miles), all within easy reach.

Lytham St Annes, in Lancashire, is roughly 7 miles from Southport and also on our list. The North West has a high share of Victorian and Edwardian terraces with rear yards and outriggers, plus large areas of inter-war semis in the suburbs.

Planning and approvals in Southport

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.

Homes in conservation areas, national parks, National Landscapes (formerly AONBs), the Broads and World Heritage Sites have tighter rules, so we always check the property's status and planning history before design starts.

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.

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.

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

What we take care of

  • Breathable wall build-up with insulation
  • Foundations, often lighter than masonry
  • Fire and acoustic details where needed
  • Cladding, render or brick slip finish

Moisture is the enemy of any timber building. We design ventilated cladding cavities, breather membranes and a proper damp-proof course height, and keep the frame dry during construction.

Timber frame extension questions answered

Do I need building regulations approval in Southport?

Yes. Almost every extension needs it, whatever the planning route. We prepare the drawings and book the inspections.

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

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

Can I see a price before committing to anything?

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

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 £1,660 to £3,230 per m² including VAT.

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.
