Removing a Wall in a Condo: Approvals and the Structural Reality

Removing a wall to open up a condo can transform how it lives — but condominiums in Singapore have their own rules, and a structural wall is never a DIY job. Here is how wall removal works in a condo, and the approvals involved.

General guidance only — confirm current BCA requirements and your development’s rules before any work.

Structural or partition? The first question

As in any home, the key question is whether the wall is load-bearing. Many condo walls are reinforced-concrete structural walls or shear walls that resist wind and earthquake loads — and those cannot simply be removed. Lightweight partitions can often go. Telling them apart reliably needs a structural engineer; the visual signs in load-bearing walls explained are only a starting point, and the same caution as in an HDB flat applies.

The approval chain in a condo

Removing or altering a structural wall in a condo typically involves three layers:

The MCST — the management corporation must approve works affecting common property or the building’s structure.
A Professional Engineer — a registered PE designs the change and endorses it, because structural works require a Qualified Person.
BCA submission — structural building works are submitted to the authorities for approval before they begin.

Skipping these is not an option for structural work: it risks the building’s integrity and your standing with the MCST.

Why a structural engineer is essential here

In a multi-storey building, the loads from above all pass down through the structure, so an opening on one floor affects everything beneath it. A structural engineer confirms whether the wall can be removed at all, and if so designs the beam and supports to carry the load safely — then provides the calculations the MCST and authorities require.

Frequently asked questions

Can I remove a wall in my condo?

A non-structural partition, often yes, with MCST approval. A structural wall requires a Professional Engineer’s design, MCST approval and a BCA submission — and sometimes cannot be removed at all.

Do I need MCST approval to renovate a condo?

For works affecting the structure or common property, yes. Internal cosmetic work usually has lighter requirements, but always check your development’s rules.

Shear walls: the ones that can never go

Beyond ordinary load-bearing walls, tall buildings rely on shear walls — stiff concrete walls, often around lift cores and stairwells and sometimes within units, that resist sideways forces from wind and earthquakes. They are fundamental to how the whole tower stands up, so they can never be removed or altered. Part of a structural engineer’s job is to identify which of your walls play this role, because no amount of beam design can replace a shear wall in a high-rise.

What removal actually involves

Where a wall can be removed, the process is methodical: the engineer assesses the wall and its loads, designs a beam and supports, and prepares the calculations; the MCST and authorities approve; the contractor props the structure, removes the wall and installs the beam; and the engineer inspects the result. It is routine work for a structural engineer, but every step exists for a reason — and in a building full of neighbours, there is no room for shortcuts.

Why condos are stricter than landed homes

A condominium is a shared structure, and that changes everything. Your unit is one part of a building that holds up — and is held up by — everyone else’s. Structural walls and shear walls may run through individual units but belong to the whole tower’s stability, so they cannot be treated as “yours” to remove. On top of the engineering and authority requirements, the management corporation has a say because the works affect common property and the building as a whole. A landed homeowner answers mainly to the authorities; a condo owner answers to the authorities and the MCST.

The MCST approval process

Most developments require you to submit renovation plans to the management before starting, particularly for anything structural or affecting common property. Expect to provide details of the works, the professionals involved, and often the engineer’s documentation for structural changes. There may be conditions on hours, protection of common areas, and a renovation deposit. Engaging the MCST early and transparently is far smoother than seeking forgiveness later — and for structural work, their approval sits alongside, not instead of, the engineer’s design and the authority submission.

Before you buy a condo to renovate

If you are buying a unit specifically to reconfigure, check what is actually possible before you commit. The walls you most want to remove may be structural or shear walls that can never go, which can undo the whole reason for the purchase. A quick structural opinion on the layout, together with a look at the development’s renovation rules, tells you whether your vision is realistic. It is far cheaper to learn this before exchanging contracts than after.

Older condos and structural quirks

Not all condominiums are built the same way. Older developments may use more load-bearing walls or have structural arrangements that limit what can be changed, while some newer ones are framed in ways that offer a little more flexibility within a unit. You cannot tell from the finishes alone, which is why a structural engineer’s read of your specific unit matters more than general assumptions about “condos”. What was possible in a friend’s apartment may be impossible in yours, and vice versa — the building, not the category, decides.

Keeping your neighbours onside

Renovating in a shared building is as much about people as engineering. Noise, dust, lift use and access all affect the households around you, and the MCST exists partly to manage that. Communicating your schedule, keeping noisy work to permitted hours, protecting common areas and being responsive to concerns goes a long way. A renovation that respects the neighbours rarely runs into trouble; one that ignores them invites complaints, delays and a strained relationship with the management for years afterward.
