Hacking Cost HDB Singapore 2026: Wall Hacking Price Guide

Knocking down a wall to open up a kitchen or combine bedrooms is one of the most transformative — and most regulated — moves in an HDB renovation. Before you swing a hammer, it pays to understand what hacking costs and what the rules allow. This guide covers HDB hacking costs in Singapore for 2026 and how to stay on the right side of the regulations.

Figures below are indicative 2026 ranges. Hacking costs depend on wall size, debris volume, and disposal, so get itemised quotes.

How Much Does Hacking Cost in an HDB Flat?

Typical 2026 ranges, including debris removal:

Disposal is a big part of the bill — always confirm it's included.

What You Can and Can't Hack

This is the critical part:

• ✅ Non-structural walls — can usually be hacked with HDB approval.
• ❌ Structural walls, columns, and beams — never; they hold up the building.
• ⚠️ Bathroom/toilet floors — restricted for a set period after key collection in new flats.

Never assume a wall is non-load-bearing. Confirm with your contractor and HDB first.

Do You Need HDB Approval to Hack a Wall?

Yes. Most hacking and wall-removal works require an HDB renovation permit, and the work must be carried out by an HDB-registered contractor. There are also area-specific restrictions. Before any hacking, read our HDB renovation permit guide to see exactly what needs approval.

What Affects HDB Hacking Cost

• Size and number of walls being removed.
• Wall material and thickness.
• Tile hacking area, priced per square foot.
• Debris volume and disposal fees.
• Unit accessibility — higher floors and tight access add labour.

Hacking as Part of a Renovation

Hacking is usually one of the first works in a renovation, before rewiring, plumbing, and finishes. It's noisy work, so it must fall within permitted renovation hours. Factor hacking into your overall budget using our renovation cost guide.

How to Save on Hacking

1. Only hack what you'll truly use — open layouts are great but not always necessary.
2. Confirm disposal is included to avoid surprise fees.
3. Bundle hacking with the rest of your renovation for one mobilisation.
4. Check structure early so you don't redesign mid-project.
5. Get itemised quotes per wall and per tile area.

What to Check Before You Hack

• That the wall is non-structural and confirmed safe to remove.
• That you have HDB approval and a registered contractor.
• That disposal and making good are included in the quote.
• That works fall within permitted hours.
• Any time restrictions on bathroom or floor hacking in new flats.

Plan Your Layout Before You Hack

Hacking is permanent, so it's worth visualising the open layout first. Upload a photo of your space to ElumiHome to see how an open-concept design would look — and be sure before you commit to knocking down a wall.
