Hacking Wall in Malaysia:
Cost & What's Allowed

General guidance for Klang Valley homeowners — not legal advice. Confirm specifics with your local council or management. Ask us on WhatsApp.

Opening up a kitchen or combining two rooms is one of the most popular and impactful renovation moves in Klang Valley homes. But not every wall can or should come down. Getting this wrong is dangerous, expensive to fix, and can compromise the safety of the entire building. Understand the wall types before any demolition commences.

Load-bearing vs partition walls

How to tell if a wall is load-bearing

• Check the building plans — the most reliable method. Structural walls, columns and beams are clearly marked on the structural drawings. For landed homes, the original architectural drawings held by the owner or council; for condos, the management holds the structural plans.
• Wall thickness — a standard half-brick partition is ~150mm (brick plus plaster). Load-bearing walls are often the same thickness but located at regular structural grid intervals. RC columns are typically 200–400mm square.
• Position and alignment — walls that sit directly above a wall on the floor below, or that align with beams on the ceiling, are more likely to be structural.
• Engage a Professional Engineer — if there is any doubt, a PE can examine the structure and confirm in writing before any hacking. A PE assessment costs RM 1,500–5,000 but is far cheaper than the consequences of hacking a structural element.

What does “hackable wall” mean?

In Malaysian renovation talk, to hack something means to break it out — usually with a hacking hammer or breaker. “Hacking wall”, “wall hacking” and “hack the wall” all mean the same job: demolishing all or part of a wall. The same word is used for floor tiles (“hacking tiles”). In Malay the job is called hacking dinding, kerja hacking or pecah dinding, and the broken brick, plaster and tile it leaves behind is the hacking debris that has to be bagged, carried down and taken away by lorry.

A hackable wall is a wall that can be taken down without affecting the building’s structure — in other words, a non-load-bearing partition, whether brick, block or drywall. Three things the label does not mean:

• It is not a legal status. A wall is only confirmed hackable by the building plans or, where there is doubt, a Professional Engineer. A verbal “this one is hackable” from anyone is not enough.
• It does not mean no approval is needed. In a condo, even a hackable partition needs written JMB/MC approval before it comes down.
• Brick does not mean hackable. Most structural walls in Malaysian homes are also brick or block, so the material tells you nothing on its own.

If a wall turns out not to be hackable, an opening may still be possible — but only with PE-stamped drawings and a beam, which moves the job from the per-sq-ft price below into the RM 15,000–40,000 bracket.

Wall type comparison for hacking decisions

Condo & strata approval

In a strata building you must get written management (JMB/MC) approval before removing even a non-structural partition wall. Structural walls, columns, beams and shear walls are strictly off-limits under any circumstances — they are part of the building structure, not your unit, and the management has an obligation to all owners to prevent structural damage.

Most condo managements also require a waterproofing certificate if any wet-area floor is disturbed during hacking, and a contractor registration form so they know who is on-site. See strata renovation rules → for the full approval process.

UBBL 1984 & building safety law

Altering structural elements without engineer-endorsed plans and council approval breaches the Uniform Building By-Laws 1984 (UBBL) and the Street, Drainage and Building Act 1974. Beyond the legal risk (stop-work order, reinstatement order, compound fine), removing a load path can cause cracking, progressive sagging or, in a worst case, partial collapse. It also voids your property insurance and creates serious problems when selling.

For landed homes, structural changes to an extension or upper-floor addition require council-approved drawings endorsed by a PE. Full details: do you need council approval? →

How much does wall hacking cost in Malaysia?

Indicative Klang Valley ranges — final cost depends on wall size, material, storey and debris disposal distance.

What a wall hacking quote should cover

Two quotes for hacking the same wall can differ by thousands of ringgit because they are not quoting the same job. Ask for a written quote that lists each of these separately:

• Hacking — the wall area in sq ft, the wall material (brick, block or drywall), and whether it is a full removal or an opening.
• Debris disposal — bagging, carrying down, and lorry disposal. Check it is included; the per-sq-ft rates above include debris removal, and the final cost depends on disposal distance and storey.
• Structural and beam check — who checks the wall type against the building plans, and whether a PE assessment (RM 1,500–5,000+) and a lintel or beam (RM 5,000–15,000+) are needed. If the quote is silent on this, ask before you sign.
• Services — isolating and re-routing any electrical cables or pipes running through the wall.
• Making good — patching, plastering, skim and paint where the old wall met the floor, ceiling and adjacent walls (RM 800–2,500 per opening), and filling the floor strip where the wall stood.
• Protection and approvals — floor and lift protection, and in a condo, the JMB/MC renovation form and deposit.

Safe hacking process

1. Identify the wall type by checking building plans or getting a PE assessment.
2. For condos: submit renovation form and obtain written JMB/MC approval.
3. For structural changes (landed home extension): prepare PE-stamped drawings and obtain council approval before any hacking.
4. Switch off and isolate any electrical circuits or plumbing pipes running through the wall before hacking.
5. Hack from top to bottom; support any lintel or floor above before removing the wall below.
6. Remove debris systematically — do not stack debris in stairwells or corridors (condo) or block the site access lane (landed).
7. Make good: patch, skim, prime and paint the floor, ceiling and adjacent walls where the old wall met them.

Open-plan conversions in Malaysia

The most popular hacking job in Klang Valley is opening up the kitchen to the dining area or removing the wall between the living and dining rooms. For most terrace houses, the wall between the kitchen and the interior dining area is a non-structural brick partition — it can be removed or a full-height opening created relatively cheaply (RM 3,000–8,000 including make-good). For double-storey homes, the wall between kitchen and dining on the ground floor may carry some load from the floor above — always check before hacking.

A half-wall or low partition wall → is a popular alternative that defines the spaces without structural risk, at lower cost than full removal.

Mistakes to avoid

• Assuming a wall is non-structural because it is made of brick — most structural walls in Malaysian homes are also built in brick or block. Brick construction does not mean non-structural.
• Not isolating services before hacking — electrical cables and plumbing pipes frequently run through walls. Hacking without isolating these first causes dangerous shorts and major water damage.
• Hacking in a condo without management approval — even removing a drywall partition triggers the management’s approval requirement; doing it without approval can result in stop-work orders and deposit forfeiture.
• Letting the contractor start before the PE confirms — verbal assurance that a wall is “just a partition” is not enough. Require the building plans to be checked before any hacking of a wall you are not certain about.
