About our steel columns & posts service in Dunoon
Planning steel columns & posts in Dunoon? Our team covers PA23 and the streets around them. The wider Argyll and Bute area is covered as well. You get one written quote for the calculations, approvals, propping, steel and making good.
Sometimes the right support for a beam is not a wall at all. A long span can be broken in two with a slim post in the middle, a beam can land on a column where the masonry below is weak, or the corner of an L-shaped opening can be held up by a single post instead of a brick pier.
Things to plan for
- Placing a post well can make an open-plan room work better. It can mark the edge of a kitchen island, frame a dining area or line up with a worktop end, so it reads as part of the design rather than an obstruction.
- Steel at floor level can corrode if it sits in damp. The detail at the base is designed to keep damp away, using grout, protective paint and the floor's damp-proof membrane, and a column in a cellar or garage may need a heavier coating.
- While the existing support is removed or the new column goes in, props hold the beam and the structure above. They are only taken out once the column is fixed, packed tight at the head and grouted at the base.
- A column delivers its load to the ground through a small area, so it normally stands on a concrete pad foundation rather than straight onto a floor slab. The pad spreads the load into firm ground at a depth set by the engineer.
- Exposed columns are commonly protected with intumescent paint applied to the thickness the specification calls for, which keeps a slim profile. Boxed columns are clad in fire-rated plasterboard and finished with corner beads, skim and a skirting to match the room.
Four stages, one team
Survey in Dunoon
We visit, look at the wall and what sits above it, measure the opening and note services, access and how the steel can be brought in.
Engineer's design
A structural engineer sizes the beam, padstones and any posts, and sets out the temporary support needed while the wall is out.
Building warrant
A building warrant is applied for from Argyll and Bute Council, and work starts only once the warrant has been granted.
Install and sign-off
Props go in, the opening is formed, the steel is set and packed, building standards inspects it, and we make good.

| Fire protection to a steel beam | £140–£550 per beam | Fire-rated board boxing or an intumescent coating system as specified |
| Kitchen-diner knock-through | £2,300–£5,450 | Internal structural wall between kitchen and dining room, steel beam, approvals and making good (kitchen fitting extra) |
| RSJ supply and fit (single beam) | £730–£2,280 per beam | Beam supplied, delivered, lifted and packed on padstones, with propping (calculations and approval priced separately) |
Figures include our approximate regional adjustment for prices in Scotland (-9%) and are rounded. How these figures are worked out.
Approvals in Dunoon
In Scotland, structural alterations need a building warrant under the Building (Scotland) Act 2003, and work must not start until the warrant is granted. For Dunoon, warrants are handled by Argyll and Bute Council's building standards service. When the work is finished, a completion certificate is submitted and has to be accepted by the council.
Scotland has no Party Wall Act. Work affecting a shared wall is governed by your title deeds and the general law, and in flats by the Tenements (Scotland) Act 2004, so it is sensible to agree the work with neighbours in writing before starting.

Steel columns & posts in Dunoon: your questions
Can you work on older or listed homes in Dunoon?
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.
Who approves steel columns & posts in Dunoon?
Structural work in Dunoon needs a building warrant from Argyll and Bute 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.
How thin can a steel support post be?
It depends entirely on the load, the height and how the post is restrained, so there is no standard size. Hollow sections often give the slimmest look for a given strength, and an engineer can sometimes reduce the section by adding restraint partway up. They specify the exact section after calculating the load.
Does a steel column need a foundation?
Almost always, yes. A column puts a concentrated load onto a small patch of ground, and most floor slabs are not designed for that. The engineer specifies a concrete pad of a set size and depth, building standards usually inspects the hole before concrete is poured, and the column is bolted down once the pad has cured.
Can I put a steel post in the middle of a beam?
Yes, a central post is a common way to support a long beam, and it often lets the engineer specify a shallower steel. The post needs its own foundation and has to sit somewhere that works with the room layout. The engineer compares a post against a single deeper beam and specifies whichever suits the loads and the space.
What happens at the survey visit in Dunoon?
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.
