Through-lounge knock-throughs in Aberdeen: how it works
If you are planning through-lounge knock-throughs in Aberdeen, the order of work matters as much as the steel: survey, calculations, approval, propping, installation, inspection and making good. That covers every postcode district in the area. We run that sequence for you as one job with one point of contact.
Things to plan for
- 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.
- Period ceilings are often lath and plaster, which can crack or sag when the wall below is disturbed. Props are set to spread load gently, and damaged areas are repaired with lime plaster or overboarded, depending on the condition and your preference.
- 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.
- 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.
- Many owners leave short nibs of wall at each end of the opening rather than going fully wall to wall. Nibs can give the beam a bearing, line up with the chimney breasts and keep the feel of two linked rooms, but the engineer decides whether they are adequate.
What happens, step by step
Free visit
A short visit to Aberdeen 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 Aberdeen City 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.

Building rules for Aberdeen
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 Aberdeen City 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.

Questions about through-lounge knock-throughs in Aberdeen
What happens at the survey visit in Aberdeen?
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.
How soon can through-lounge knock-throughs start in Aberdeen?
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.
Is the wall between two reception rooms load-bearing?
In most period terraces and semis it is, because it carries the floor joists and the wall between the bedrooms above. Some later houses have lighter partitions in this position, so the only way to be sure is an engineer's inspection. We arrange this during the survey and design stage.
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.
Can I keep the cornicing when the wall comes down?
Usually yes. The existing cornice in each room is protected during the work, and a matching profile can be run or cast to bridge the opening once the beam is boxed and plastered. How closely it matches depends on the original design and its condition, which we check at the survey visit.
Will the ceiling crack when the wall is removed?
Some minor cracking in old lath and plaster ceilings is possible, even with careful propping, because the structure is being disturbed. We prop to spread the load and protect ceilings where we can, and any cracks are filled or repaired as part of making good. Sound plaster normally stays intact.
