Rear extension steels in Stonehaven: how it works
We carry out rear extension steels in Stonehaven, covering the AB39 postcode district. The wider Aberdeenshire area is covered as well. The job starts with a free survey visit so the engineer's calculations are based on your actual walls, floors and loads.
We work alongside your builder or as the steel package within the wider build. We arrange the engineer's design, coordinate building standards, prop and open the rear wall at the right stage of the programme, and fit and pack the steels so the extension can be finished around them.
Key points for your project
- The original rear wall of most houses is load-bearing because it supports first-floor joists and the bedroom wall above. Even where the joists run parallel to it, the masonry overhead still needs carrying, so steel is almost always part of opening it up.
- Columns carry concentrated loads, so each normally sits on a pad foundation designed by the engineer. Digging these inside an existing kitchen or through a solid concrete floor takes planning, especially where drains run close to the back wall.
- Soil stacks, waste pipes, boiler flues and gas meters are often fixed to the back wall. These are moved before the wall opens, and any work on gas pipework must by law be carried out by a Gas Safe registered engineer.
- Opening the rear wall is usually the dustiest stage of an extension project. The work face is sheeted off from the rest of the house, and the kitchen is often out of use for a few days while the opening is formed and the steel goes in.
- A single beam works where solid masonry is left at both ends of the opening. Where the opening runs nearly the full width or the corners are weak, the engineer may use columns or a goalpost frame, which is two posts and a beam bolted together.
How the job runs in Stonehaven
Free visit
A short visit to Stonehaven to see the job, agree what you want and check the bearings, floors and services that affect the design.
Calculations
The engineer's calculations and a simple drawing are prepared for your opening and shared with you before anything is ordered.
Building warrant
A building warrant is applied for from Aberdeenshire Council, and work starts only once the warrant has been granted.
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.
How much should I budget in Stonehaven?
As a guide, budget £2,300–£6,350 including VAT for opening into a rear extension in Stonehaven, based on published UK cost guides adjusted for prices in Scotland (-9%).
| Job | Typical guide range | What it usually covers |
|---|---|---|
| Opening into a rear extension | £2,300–£6,350 | Original rear wall removed with a beam or goalpost, approvals and propping, coordinated with the extension build |
| Steel column or post | £460–£1,360 per column | Column supplied and fitted with base and cap plates on a pad foundation |
| Side return extension steelwork | £3,200–£7,750 | Beams and posts along the old side wall line, propping and approvals (extension build extra) |
Figures include our approximate regional adjustment for prices in Scotland (-9%) and are rounded. How these figures are worked out.
Approvals in Stonehaven
Scottish rules are stricter on timing than in England: the building warrant must be in place before the wall is touched. We prepare the application with the engineer's calculations and submit it to Aberdeenshire Council. The finished work is then certified and a completion certificate submitted for acceptance.
There is no party wall notice system in Scotland. Instead, check your title deeds and, for flats, the tenement management scheme, and talk to neighbours early if the beam bears into a shared wall.
Rear extension steels in Stonehaven: your questions
How much do rear extension steels cost in Stonehaven?
As a guide, budget £2,300–£6,350 including VAT for opening into a rear extension in Stonehaven, based on published UK cost guides adjusted for prices in Scotland (-9%). The exact figure depends on the span, what the wall carries, access and the finish, and is fixed in writing once the scope is agreed.
How soon can rear extension steels start in Stonehaven?
Start dates depend on the engineer's calculations, the building warrant and any agreement needed with neighbours. We give you a realistic timetable after the survey and keep you updated as each approval comes through.
What is a goalpost frame in an extension?
A goalpost frame is two steel columns with a beam across the top, bolted together and standing on their own foundations. It is used where the opening is so wide that little masonry is left to bear on, or where the existing corners cannot take the load. The engineer decides whether one is needed.
Will my kitchen be out of action while the rear wall is opened?
For a few days, usually. The kitchen often sits against the rear wall, so units, sinks or appliances near the opening may need disconnecting while the wall is propped and removed. The work area is sheeted off and the rest of the house stays in use.
How wide can a rear extension opening be?
There is no fixed limit, and openings across the full width of a house are common with the right steel. The engineer sizes the beam or frame for the span and the loads above. Wider spans need deeper or heavier steel and possibly columns, which affects headroom and cost.
Who approves rear extension steels in Stonehaven?
Structural work in Stonehaven needs a building warrant from Aberdeenshire Council, granted before work starts. We prepare and submit it with the structural engineer's calculations and arrange the inspections, so the completion paperwork follows the job.
