About our through-lounge knock-throughs service in Inverness
For homes in Inverness and the IV1, IV2 and IV3 districts, we handle through-lounge knock-throughs from survey to sign-off. Our coverage runs across the Highlands, so nearby villages are included too. The beam is sized by a structural engineer and inspected before it is boxed in.
Many period terraces and semis were built with a front parlour and a back sitting room divided by a solid brick wall. Opening them into one through-lounge brings light from both ends of the house, but that wall commonly carries the floor joists, the wall between the bedrooms above and sometimes part of the roof load too.
Worth knowing before you start
- Victorian brickwork is usually laid in soft lime mortar and the internal walls may be only one brick thick. The engineer allows for this when designing the bearings, and padstones are often used to spread the beam's load over the weaker masonry.
- The steel commonly needs fire protection to meet building regulations, usually by boxing it in fire-rated plasterboard and skimming it. In period rooms the box can be finished with a matching cornice so it reads as part of the original ceiling.
- If the house is listed, internal structural alterations need listed building consent as well as a building warrant. Conservation area status does not usually affect internal work, but flats within converted period houses normally need the freeholder's consent.
- Radiators, pipe runs and sockets on the dividing wall need relocating. Older houses sometimes have heating pipes running under the floor along the wall line, so these are traced and moved by a heating engineer before the wall comes down.
- In most terraced houses the wall between the front and back rooms runs across the house and carries the floor above, plus the wall between the front and back bedrooms. It is normally load-bearing, but the engineer still checks before any design is drawn up.
How the job runs in Inverness
Survey in Inverness
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 The Highland 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.

Building rules for Inverness
Steel beam work in Inverness needs a building warrant from The Highland Council. The structural design is part of the application, and the council's building standards team accepts the completion certificate once the work is done as approved.
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 through-lounge knock-throughs start in Inverness?
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 Inverness for through-lounge knock-throughs?
Yes. We carry out through-lounge knock-throughs in Inverness and the IV1, IV2 and IV3 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 consent to knock through in a listed building?
Yes, you need both listed building consent and a building warrant. Listed building consent from the local planning authority covers internal structural changes to the building's fabric, and building standards covers the structural safety. Carrying out works to a listed building without consent is an offence, so it must be in place before anything is booked.
What happens to the floor where the wall was?
A strip of exposed joists, or a footing in a solid floor, is left where the wall stood. Timber floors are patched with matching or reclaimed boards, and solid floors are filled and levelled. If you are fitting a new floor across both rooms, it is simply prepared level for the new finish.
Should I keep the chimney breasts when knocking through?
Most people do, because the breasts frame the opening and support the stack above. Removing a chimney breast is a separate structural job needing its own design and approval, and it affects your neighbour if the stack is shared. Keeping them usually simplifies the steelwork and preserves the character of the room.
What happens at the survey visit in Inverness?
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.
