Working in Ulverston

We cover Ulverston and the postcode districts LA12. Neighbouring towns we cover include Barrow-in-Furness (9 miles), Kendal (16 miles), Whitehaven (31 miles), Penrith (34 miles).

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.

Who a double-storey extension suits

  • Houses with enough distance to the rear or side boundary
  • Growing families who need a bedroom as well as a bigger kitchen
  • Homeowners who would otherwise consider moving

Planning rules that apply in Ulverston

In England a two-storey rear extension is permitted development only if it projects no more than 3 m from the original rear wall, sits at least 7 m from the rear boundary, matches the roof pitch and uses obscure, non-opening side windows upstairs. Most two-storey extensions therefore go through a householder planning application, which costs £548 from 1 April 2026 and normally takes about 8 weeks.

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.

Building regulations approval is separate from planning. In England you can use the council's building control team or a registered building control approver; a full plans application gets the drawings checked before work starts, and the inspector signs the work off with a completion certificate.

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

Our process, step by step

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 draw the design, agree it with you and handle planning or permitted development checks and building regulations.

  3. Fixed written price

    We confirm the build price in writing, based on the approved drawings and the finishes you have chosen.

  4. Build and sign-off

    The build is managed from start to finish, inspected at each stage and signed off on completion.

Common questions in Ulverston

How long does a double-storey extension take to build in Ulverston?

On site, typically 16 to 24 weeks once approvals are in place. Before that, allow 8–16 weeks design and approvals.

Do I need building regulations approval in Ulverston?

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

Can I see a price before committing to anything?

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

Do I need a Party Wall Agreement?

If you are in England or Wales and the work involves a shared wall or digging foundations close to a neighbour, the Party Wall etc. Act 1996 applies and notices must be served before work starts. We tell you which notices are needed.

Is a two-storey extension cheaper per square metre?

Usually. Our guide range is about £1,470 to £2,850 per m² of new floor area including VAT, compared with £1,660 to £3,230 per m² for single-storey work, because the foundations and roof are shared across two floors.
