Double-storey extensions in Godalming

Homeowners in Godalming can get double-storey extensions from one company: the design, the paperwork and the building work sit with us rather than with three separate firms.

Covering Godalming

Godalming sits 4 miles south-west of Guildford, with Guildford 4 miles to the north-east and Aldershot 8 miles to the north-west.

Homes in the South East

Housing across the South East mixes inter-war semis, post-war estates and older cottages in villages and market towns, so rear and side extensions, hip-to-gable lofts and garage conversions all come up regularly.

What do you get with a double-storey extension?

Two-storey work has to sit comfortably with the house and the neighbours, so most of the design effort goes into the roofline, window positions and how the new first floor connects to the landing. We handle the planning application, the structural design and the building control process, then build, roof and finish both floors.

  • Householder planning application
  • Structural engineer’s design and calculations
  • Windows, insulation, plastering, electrics and plumbing

What approvals does a double-storey extension need in England?

In England we deal with the council’s planning team for permission or a lawful development certificate, with building control (the council or a registered building control approver) for inspections, and with neighbours under the Party Wall etc. Act 1996 where it applies.

Two-storey rear extensions can sometimes be permitted development in England (no more than 3 m deep, at least 7 m from the rear boundary, roof pitch to match), but most two-storey and all two-storey side extensions need householder planning permission.

What can affect a double-storey extension?

  • Side extensions close to a boundary are often set back or stepped down so they do not create a terraced effect.
  • Neighbours’ light is assessed using the 45-degree guide many councils use.

  3. Design and fixed price. You get drawings and a written price for the agreed specification before anything is ordered.
