Things People Forget When Removing Walls in Older Homes

Things People Forget When Removing Walls in Older Homes

Opening up spaces in older homes is one of the most popular renovation goals. Removing walls can create light-filled, open-plan living areas that suit modern lifestyles. But in heritage and character homes, taking out walls is rarely straightforward and often comes with hidden challenges.

At W O Flatz Construction Ltd, we’ve guided many Auckland homeowners through wall removals as part of larger renovations. Here are the key details people often forget—and how to plan with confidence.

1. Many Walls Are Load-Bearing

In older homes, internal walls often support roof structures or upper floors. Removing them without proper planning can compromise the stability of the entire building.

Tip: Always have a structural assessment carried out before work begins. Your builder may need to install beams, lintels, or posts to safely redistribute loads.

2. Ceilings and Floors May Be Uneven

Once a wall is removed, uneven ceiling lines or floor levels often become more noticeable—especially in older houses that have settled over time.

Tip: Budget for extra work to level and blend these areas, ensuring the new open space looks seamless.

3. Unexpected Wiring and Plumbing Can Be Hidden

Older homes often have services running through walls. Electrical cabling, plumbing pipes, and even gas lines are sometimes discovered mid-demolition.

Tip: Plan for possible service rerouting and include an allowance in your budget for this work.

4. Heritage Rules May Apply

If your home is in a heritage or character area, removing certain walls—especially if they affect the exterior or significant features—may require resource consent.

Tip: Check with Auckland Council early to understand any restrictions or approvals needed.

5. Dust and Disruption Are Inevitable

Taking down walls creates a significant amount of dust and debris. In occupied homes, protecting adjacent rooms and managing disruption is essential.

Tip: Work with a builder who prioritises site cleanliness and can stage work to minimise impact on your living spaces.

6. Open Spaces Need Structural and Acoustic Planning

Once a wall is gone, larger open-plan spaces often require additional considerations for structural stability, insulation, and noise management.

Tip: Your builder can advise on options like engineered beams and acoustic insulation to keep your home comfortable and quiet.

7. Budget for the Unexpected

In older homes, it’s common to uncover hidden issues once walls are opened up—such as rot, pest damage, or non-compliant work from previous renovations.

Tip: Allow a 10–15% contingency in your budget for unforeseen repairs.

8. Work With a Builder Who Understands Older Homes

Removing walls in older houses requires experience and respect for traditional building methods. At W O Flatz Construction, we specialise in carefully adapting character homes while maintaining their integrity and charm.

In Summary

Removing walls in an older home can create stunning open spaces, but it’s not without challenges. With careful planning, expert advice, and an experienced builder, you can achieve a safe, seamless transformation.
