The 7 Questions to Ask Before You Knock Through a Wall

If you’ve ever stood in your kitchen staring at a wall thinking, “If that was gone, this place would be unreal” — you’re not alone.

Open-plan living is still one of the most popular upgrades we see across Edinburgh and East Lothian. But here’s the myth we need to kill early:

Not every wall is “just a wall.”

Some are holding up floors, roofs, or the structure above. Get it wrong and you don’t just create a mess — you create risk, delays, and big unexpected costs.

So if a knock-through is on your mind this year, here are the 7 questions we’d want you to ask before you lift a hammer.

1) Is it load-bearing (or doing something important)?

A wall can be:

• Load-bearing
• Supporting joists
• Bracing the building
• Hiding structural steel from a previous alteration

Assume nothing. The only way to know is proper assessment (and often a structural engineer).

2) What’s above it?

Sounds obvious, but people forget to look up.

Ask:

• Is there a bathroom above?
• Is it a chimney breast nearby?
• Do the floor joists run into that wall?

What’s above often tells you what the wall is doing.

3) What services are inside it?

Walls love hiding surprises:

• Electrics
• Plumbing
• Gas runs
• Ventilation ducts

If you’re knocking through, plan for rerouting services. That’s not a “maybe” — it’s usually a “when”.

4) What’s the plan for support (RSJ/steel/beam)?

If it’s structural, you’ll likely need a beam (often an RSJ) and proper padstones/bearing details.

This is where jobs go wrong when people try to wing it.

Good work looks boring: correct calculations, correct install, correct inspections.

5) Do you need Building Control sign-off?

In most cases, structural alterations need Building Controlinvolvement.

It protects you:

• Safety-wise
• Insurance-wise
• Resale-wise

If you ever sell the property, paperwork matters.

6) How will you manage dust, noise, and neighbour impact?

A knock-through isn’t a tidy job.

A solid plan includes:

• Dust control and protection
• Waste removal
• Working hours
• A quick heads-up to neighbours

It’s not just being polite — it prevents complaints and keeps the job moving.

7) What’s the domino effect on the rest of the room?

Removing a wall often means:

• New flooring (because the old flooring won’t match)
• Plastering and making good
• Ceiling repairs
• New lighting layout
• Heating changes

This is where budgets get caught out.

The knock-through is the start — not the finish.

Quick reality check: what does a knock-through actually involve?

1. Site visit + assessment
2. Structural engineer calcs (if needed)
3. Temporary supports
4. Remove wall safely
5. Install steel/beam
6. Make good (plastering, finishes)
7. Building Control sign-off (where required)

If someone tells you it’s “a one-day job, no paperwork, no bother”… be cautious.
