Converting a garage is a popular way to add a room without extending. Structurally, two things usually happen: the big garage door opening is filled in with a wall, window or door on proper foundations, and a doorway or wider opening is formed through the wall between the garage and the house.

Key points for your project

  • Garages often hold gas meters, consumer units, boilers or water stopcocks. These are located at survey, and anything that needs moving is done by the right trade, including a Gas Safe registered engineer for any work on gas pipework.
  • Garage floors often sit lower than the house floor and may have no damp-proof membrane. The infill wall needs a damp-proof course linked to the existing walls, and the floor usually needs a membrane, insulation and screed raised to the house level.
  • The structural part of a garage conversion, covering the infill foundation, the wall and any new opening, typically takes one to two weeks. The full conversion with insulation, electrics, plastering and flooring takes longer, depending on the scope.
  • An infill wall needs a proper foundation. Garage floors are often a thin slab with no footing under the door line, so a new trench footing is usually dug across the opening to a depth and width the engineer and building control agree.
  • The beam or lintel over a garage door was designed to span an open gap. It may be timber, concrete or steel, and in older houses it can be undersized or corroded, so the engineer checks it before anything is built underneath or above it.

From survey to sign-off in Lowestoft

  1. Free visit

    A short visit to Lowestoft to see the job, agree what you want and check the bearings, floors and services that affect the design.

  2. Calculations

    The engineer's calculations and a simple drawing are prepared for your opening and shared with you before anything is ordered.

  3. Building control

    We submit a building notice or full plans application to the local council's building control team, so approval is in place before the wall is touched.

  4. Steel in, made good

    On site we prop, open up, fit and pack the steel, then fire protect, box in and plaster once the inspection is done.

Approvals in Lowestoft

Structural openings in English homes need building regulations approval before work starts. The local council's building control team can deal with it, or you can use a registered building control approver. Either way the steel is inspected before it is covered, and a completion certificate is issued at the end. Keep it safe for when you sell.

Terraced and semi-detached homes often need party wall notices, because cutting into a shared wall to take a beam end is notifiable under the Party Wall etc. Act 1996. Allow at least two months for the notice period unless your neighbour agrees sooner.

Garage conversion openings in Lowestoft: your questions

Can you work on older or listed homes in Lowestoft?

Yes. Older homes often have lime mortar, timber lintels or shallow footings, which the engineer allows for. Listed buildings need listed building consent for internal structural changes as well as building regulations approval, and that must be in place first.

Do you cover Lowestoft for garage conversion openings?

Yes. We carry out garage conversion openings in Lowestoft and the NR32 and NR33 postcode districts. Book a free survey visit and we will check the wall, arrange the engineer's calculations and send an itemised written quote.

What happens to the beam over my garage door?

It is checked by the engineer. Many can stay, carrying the wall above as before, with the infill built underneath. If it is timber that has rotted, a corroded steel section or simply undersized for the loads, it is replaced, with the wall or room above propped while the new steel goes in.

What paperwork will I get when the conversion is done?

You should receive the engineer's calculations, a building control completion certificate for the conversion, and certificates for any electrical or gas work. Keep these together, as buyers' solicitors ask for evidence that a garage conversion was approved, especially where a garage has become a bedroom or living space.

How long do the structural works for a garage conversion take?

Typically one to two weeks for the structural stage: digging and concreting the infill foundation, building the infill wall, and forming any new opening into the house. Building control inspections fit around these stages, and the insulation, electrics, plastering and flooring of the conversion follow on afterwards.
