About our basement & cellar steels service in Dunoon
Dunoon has a mix of housing, and basement & cellar steels need a slightly different approach in each. The wider Argyll and Bute area is covered as well. Whatever the age of the property, the steel goes in on proper bearings with temporary support in place throughout.
Turning a cellar into a habitable room, or digging a new basement, nearly always means moving or removing walls that hold up the rest of the house. Steel beams and columns take over that support, often while the existing walls are being deepened by underpinning and the space is protected against water.
Worth knowing before you start
- Headroom is precious below ground, and a deep downstand beam can make a room feel cramped. The engineer may use a shallower but heavier section or set the steel into the ground floor zone, and that choice is made at design stage.
- Underpinning deepens the existing foundations so walls can go lower, and a specialist carries it out in a strict bay-by-bay sequence. Steelwork has to fit around that sequence, which is why the engineer plans the two together from the start.
- Temporary works for basements are more involved than for a single opening. The design covers propping the house above, supporting the sides of the excavation, and keeping loads off freshly cast concrete until it has gained strength.
- Cellars often house gas meters, the incoming water main, the electricity supply and old drainage. These are mapped before work starts, gas work must by law be done by a Gas Safe registered engineer, and the electricity network operator may need to move a supply.
- Getting steel into a basement means lowering it through a lightwell, a stair opening or a temporary hole in the ground floor. Long beams may be designed in bolted sections so they can be handled in tight below-ground spaces.
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.
What do basement & cellar steels cost in Dunoon?
As a guide, budget £2,300–£5,900 including VAT for basement or cellar steelwork in Dunoon, based on published UK cost guides adjusted for prices in Scotland (-9%).
| Job | Typical guide range | What it usually covers |
|---|---|---|
| Basement or cellar steelwork | £2,300–£5,900 | Beams and columns with pad foundations under the floor above (excavation and waterproofing extra) |
| Structural calculations for a beam | £230–£680 | Site measure or photos, beam and padstone design and calculations for building standards |
| Steel column or post | £460–£1,360 per column | Column supplied and fitted with base and cap plates on a pad foundation |
| Temporary works and propping | £140–£460 | Props, spreaders, needles and sole plates for a typical opening, installed and struck |
Figures include our approximate regional adjustment for prices in Scotland (-9%) and are rounded. How these figures are worked out.
Building control and neighbours in Dunoon
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 Argyll and Bute 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.

Local questions answered
How soon can basement & cellar steels start in Dunoon?
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.
Do you cover Dunoon for basement & cellar steels?
Yes. We carry out basement & cellar steels in Dunoon and the PA23 postcode districts. Book a free survey visit and we will check the wall, arrange the engineer's calculations and send an itemised written quote.
Do I need steel beams for a cellar conversion?
Often, yes. If any cellar walls are being removed or opened up, or the ground floor above is being altered for a stair or lightwell, steel beams and columns are usually needed to carry the house above. A structural engineer looks at the layout and loads and specifies the steelwork.
How much headroom do I need for a basement conversion?
Enough for the finished room to be comfortable and for the stair to meet the building regulations headroom rules. Steel depth affects that, so the engineer may choose a shallower section or set beams within the floor above. Where headroom is too tight, lowering the floor with underpinning may be an option.
Can I stay at home while basement steels are installed?
Many people do, particularly for cellar conversions where the dig is limited. Expect noise, dust and deliveries during the heavier stages, and some rooms above may be out of use while props are in place. For large excavations, moving out for part of the programme can be more comfortable.
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.
