Home Extensions & Structural Joinery

Structural joinery for extensions: frames, beams, openings, finishes.

Home Extensions & Structural Joinery in Motherwell and Lanarkshire — Surma Joinery

What's included

  • Structural openings: lintels, steel beam installation, padstones
  • Stud and timber frame construction for new walls
  • Floor joist installation, levelling, strengthening
  • Roof framing, trussing, sarking, lath where the architecture calls for it
  • First-fix joinery and coordination with brickwork, plumbing, electrics
  • Second-fix finishes: skirting, architraves, doors, windows

Extensions are mostly bricklayer-led, but the joinery is what decides whether the end result feels like a real part of the house or a tacked-on box. Framing, openings, roof structure, then the doors and skirting that tie it back to the original rooms.

We work as the joinery lead on most extensions in Lanarkshire — usually alongside a brickwork team and an architect-managed warrant. If you are at the point of working out what is actually possible on your plot, come to us early. A site visit is free and we will save you money by ruling things out before the architect bills three drawings of impossible.

Our process

  1. 01

    Consultation

    We come out, look at what you are trying to do, and tell you the honest version of cost and timescale. Sometimes we suggest you do something different than you came in with.

  2. 02

    Coordination

    For full extensions we are part of a team — usually architect, structural engineer, brickwork lead, ourselves on joinery. We work to a programme and turn up when the brickie says we are needed.

  3. 03

    Structural work

    Openings, beams, frames, floors. The bones of the extension that decide whether it stands up properly for thirty years.

  4. 04

    Finishes

    Once the brickwork and plastering are done we come back for doors, skirting, architraves, kitchen if there is one. The bit you actually see.

Frequently asked

Do you do full extensions or just the joinery?
Both, depending on the project. On bigger jobs we tend to lead the joinery package and work alongside a brickwork team. On smaller single-storey rear extensions we can manage the whole job for you.
Who pulls the building warrant?
We work with a partner architect who handles warrant submission. The fee is in the quote upfront. Allow three to six months for warrant approval before any spades go in.
Can you install RSJs and structural steel?
Yes. Beam sizing comes from the structural engineer attached to your warrant. We handle installation, padstones, and making good around the steel.
How long does a single-storey rear extension take?
Twelve to twenty weeks on site once the warrant is through and the slab is in. Bigger or two-storey work runs longer.
What is the difference between an extension and a conversion?
An extension adds new external footprint to the house. A conversion changes the use of existing space (loft, garage). Conversions are usually cheaper and faster because the shell is already there.
