Overview

A well-planned house extension can give you the extra room your home is missing without the cost and upheaval of moving. That could mean a bigger kitchen where family life actually fits, a brighter living space opening onto the garden, or an extra bedroom to take the pressure off a busy household.

The difference with Carter Langfold is that you deal with one point of contact from planning coordination through to the final coat of paint. Planning permission and building regulations are two separate approvals, and we review your property to establish what applies — including permitted development limits, listed status and conservation area rules — before managing the right submissions alongside structural engineering support. Groundworks, structure, roofing, glazing, plastering, electrics and plumbing are all coordinated by one project lead, so the build keeps moving instead of stalling between separate contractors.

What's Included

  • Drawings and the planning application where one is needed
  • Building control fees and inspections, with the completion certificate at the end
  • Foundations designed from a trial hole for the actual ground
  • Structural steel, walls, roof and glazing
  • Electrics, plumbing, plastering and the fit-out if you want it
  • Party wall notices explained and the programme built around them

Many extensions projects qualify for flexible finance options, and every job starts with a free, no-obligation survey so you know the full scope before committing.

Extensions project 2

Rear, side and wrap-around extensions, from foundations to finish. Excavation, footings, drainage and slab are done properly because everything else stands on it, and steels are designed and installed to open up the existing house into the new space.

Structural calculations may be needed for beams, foundations and new openings, especially where you want larger glazed doors or an open-plan layout. We coordinate the right submissions and support before work starts, which helps avoid delays halfway through the job. Roofing, windows and doors are matched or contrasted to the existing house as the design calls for, with plastering, electrics, plumbing and decoration handled under the same project lead.

We provide Extensions for clients throughout The Midlands

"Very professional service throughout, from initial survey through to the sprayfoam being taken out. Each stage was clearly explained, and my loft was left immaculate."

"Couldn't thank this company enough for successfully removing the sprayfoam from my auntie's house — the property couldn't be sold until it was signed off by the bank's surveyors."

"Marcus & the team removed my spray foam last week. Very professional & left no mess. They replaced my old felt with a new membrane as it was falling apart."

"Carter Langfold spent 5 days correcting a mess done by another company in an attempt to remove spray foam from our loft. The team led by Manager Marcus were brilliant throughout."
