About our garage conversion openings service in Havant

We cover garage conversion openings in Havant (PO7, PO9) and the streets around it. It sits about 6.1 miles from Portsmouth, which we also cover. Each job is designed by a structural engineer and approved through local building control before work begins.

For integral garages with a bedroom above, the beam over the garage door matters even more, because it carries the front wall of the room upstairs. We arrange the survey visit, engineer's calculations, building control, propping, any steel and making good, with the structural items set out in one itemised written quote.

What to expect

  • The price depends on whether the garage door beam needs replacing, the foundation needed for the infill, whether a new opening is formed into the house, the brick or cladding finish, and any fire separation work that has to be kept or added.
  • Forming a doorway from the house into the converted garage often goes through a load-bearing wall, especially the original external wall of the house where the garage is attached. That opening needs a lintel or beam designed by the engineer.
  • Once the garage becomes a habitable room, the energy efficiency requirements of the building regulations apply. Walls, floor and roof normally need insulating to current standards, so the structural design and the thermal upgrade are planned together.
  • Most garage conversions do not need planning permission, but some estates have conditions removing permitted development rights for garages, and listed buildings or flats need consent. Changing the front elevation can also need permission in some areas.
  • 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.

From survey to sign-off in Havant

  1. Look and measure

    We check the wall, the span you want and what the wall is carrying, and photograph anything the engineer needs to see.

  2. Design and price

    Calculations come back from the engineer and we confirm your fixed written price, line by line.

  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. Fit, inspect, finish

    The work is propped and the steel installed and packed tight. After inspection the opening is boxed, plastered and left clean.

Building control and neighbours in Havant

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.

If the beam bears into a wall you share with a neighbour, the Party Wall etc. Act 1996 applies, and a party structure notice must be served at least two months before that work starts. We arrange this through a party wall surveyor.

Questions about garage conversion openings in Havant

Do you cover Havant for garage conversion openings?

Yes. We carry out garage conversion openings in Havant and the PO7 and PO9 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 at the survey visit in Havant?

We look at the wall, the floor and ceiling either side and what sits above, measure the opening you want, and note cables, pipes and access for the steel. It usually takes under an hour and there is no charge.

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.

Can I knock through from my garage into the kitchen?

Usually, yes. The wall between an attached or integral garage and the house is often load-bearing, so the opening needs a lintel or steel beam designed by a structural engineer and approved by building control. If any of the garage stays as storage, the opening needs fire separation, such as a fire door.

Is my garage floor suitable for a living room?

Rarely as it stands. Garage floors are often lower than the house, may slope towards the door and usually lack insulation and a damp-proof membrane. The floor is normally built up with a membrane, insulation and screed or a timber floor to meet the house level and the building regulations.

Do you also work near Havant?

Yes. We also cover nearby towns including Waterlooville, Portsmouth, Gosport and Fareham.
