What through-lounge knock-throughs involve in Edinburgh
If you are planning through-lounge knock-throughs in Edinburgh, 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.
Key points for your project
- 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.
- 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.
- The structural stage for a through-lounge typically takes three to five working days. Both reception rooms are out of use for that time, so furniture is moved out or stacked and sheeted, and the hallway is kept clear as the main walkway.
- Ornate cornicing often runs around both rooms and stops at the wall being removed. Where practical, the run is extended across the opening by matching the profile, either run in place or cast, so the joined room looks original rather than patched.
- 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.
Four stages, one team
Free visit
A short visit to Edinburgh 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 City of Edinburgh 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.

Approvals in Edinburgh
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 Edinburgh, warrants are handled by City of Edinburgh Council's building standards service. When the work is finished, a completion certificate is submitted and has to be accepted by the council.
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.

Through-lounge knock-throughs in Edinburgh: your questions
How much do through-lounge knock-throughs cost in Edinburgh?
As a guide, budget £2,300–£5,000 including VAT for through-lounge knock-through in Edinburgh, 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.
What happens at the survey visit in Edinburgh?
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.
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.
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.
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.
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.
Do I need a party wall agreement for through-lounge knock-throughs in Edinburgh?
There is no Party Wall Act in Scotland. Your title deeds and the general law apply instead, and the Tenements (Scotland) Act 2004 for flats, so agree the work with your neighbour in writing before it starts.
