I’m planning to open up my kitchen and lounge by removing a wall inside my house.
I’m not sure if it’s load-bearing or not, and I don’t want to take risks.
I’m trying to understand:
- How do I know if a wall is load-bearing?
- Do I need building consent to remove it?
- Do I need an engineer or structural drawings?
- What could happen if I remove it without checking?
Just want to make sure I don’t cause structural problems.
Short answer: If it’s load-bearing — yes, you almost always need consent.
Why this matters
In NZ timber-framed houses (typically built under NZS 3604):
Internal walls can:
- Support roof loads
- Carry ceiling joists
- Transfer structural loads
👉 Removing the wrong wall = structural failure risk
⚠️ Big mistake people make
“It’s internal, so it must be safe to remove”
Not always.
What can go wrong
We’ve seen:
- Sagging ceilings
- Cracks in plasterboard
- Doors not closing properly
Worst case → structural instability

😄 Reality check
If removing the wall was easy…
engineers wouldn’t exist 😅
What professionals do
- Calculate loads
- Design beam size
- Check deflection limits
- Ensure compliance
