Renovations and extensions

Extensions and renovations in Barnsley, foundations to finish

We build extensions, annexes and garden rooms and renovate houses across Barnsley, from taking a home back to brick to opening up a ground floor with new steels. The footings are dug by our own groundworks team, so nothing waits on another firm. Call Liam on 07709 099108 for a free look.

What renovation and extension work do we do in Barnsley?

Full refurbishments, single storey extensions, annexes, garden rooms and structural alterations. We take houses back to brick and put them together again, including the steels, the new openings and the parts that need signing off by Building Control.

The difference with us is where the job starts. On most extensions the builder brings in a groundworker to dig the footings, then waits for them. Ours are dug by our own team, the same people who put in foundations and drainage on commercial sites, so the start of your job is in our diary, not somebody else's. Liam brings 17 years in the trade to every one of them.

Do you need planning permission for an extension in Barnsley?

Often not, but Building Regulations nearly always apply, and the two are easily confused. Planning is about what the extension looks like and how it affects the neighbours. Building Regulations are about whether it is built safely: foundations, structure, insulation, drainage and fire safety. These are the general rules in England. Your council has the final say on planning, and we will tell you which route your job is on before you spend anything.

What usually applies to common jobs

JobWhat usually applies
Single storey rear extension up to 3m deep (4m on a detached house)Usually permitted development, so no planning application. Building Regulations still apply.
Single storey rear extension up to 6m deep (8m detached)Prior approval from the council first, which includes a 21 day consultation with your neighbours.
Taking out a load-bearing wallNo planning permission, but it needs Building Regulations approval and a structural engineer's calculations for the steel.
Garden roomOften permitted development if it stays within the height and size limits, which are tighter close to a boundary. Using it as a bedroom or a separate home changes that.
Listed building or conservation areaCheck with the council before anything else. The usual allowances are reduced or do not apply.

How a load-bearing wall comes out

  1. The steel is designed

    A structural engineer works out the load and sizes the beam and the padstones it sits on. Those calculations go to Building Control.

  2. The floor above is propped

    Temporary props take the weight of the floor and walls above before a single brick comes out.

  3. The wall comes out and the steel goes in

    The opening is cut, the padstones are bedded and the beam is lifted onto them.

  4. It is inspected

    Building Control check the bearings and the fire protection to the steel before it is covered up.

  5. Made good

    The beam is boxed in, the walls and ceiling are plastered and the floor is joined through, so the new opening looks as if it was always there.

What is it like having us in your house?

A renovation is disruptive however well it is run, so we keep the parts we control predictable. You get an itemised written price, so you can see what is materials and what is labour. We agree a start date and tell you how long the job will take, and if the weather or a supplier moves it, you hear it from us. The house is swept and cleared each evening, not left in a mess until the last day. Payments are in stages tied to work you can see, with no large deposit up front and the last payment after you have looked round and you are happy.

Finishing the rooms, not just the structure

An extension is only half done when the roof is on. We carry on through the fit-out, with kitchens, bathrooms and fitted joinery such as media walls and alcove units, and on fit-out every trade is ours or somebody we have worked with for years. Outside, the patio beyond new bifold doors or the drive at the front can be part of the same job.

Extension and renovation questions

  • Do I have to tell my neighbours before an extension goes up?

    Often, yes, under the Party Wall Act. If you are building on or up to the boundary line, or digging foundations within 3 metres of a neighbour's building and deeper than their foundations, you have to serve them notice first, at least a month ahead and longer for work to a shared wall itself. It is worth a friendly word well before the formal notice arrives.

  • Does a small opening, like a new doorway, need an engineer?

    If the wall is load-bearing, yes. A doorway still needs a lintel sized for what is above it, and it still comes under Building Regulations. Whether a wall is load-bearing is not always obvious from inside the room, so it is worth checking before anyone picks up a hammer.

  • What paperwork should I have when the job is finished?

    For anything that went through Building Control, a completion certificate, plus the structural calculations if a wall came out. Keep them with the deeds. A buyer's solicitor will ask for them when you sell, and missing sign-off on an old alteration can hold a sale up.

  • Can we live in the house while the work is done?

    For most jobs, yes. The hard stretches are the days when the kitchen or the only bathroom is out, when a wall is coming down, and when the new extension is knocked through into the house. Ask at the visit how long each of those will last on your job, so you can plan round them.
