Do I need approval to renovate a condo in Singapore?

Yes. Renovations need sign-off from the condo's management, the MCST, usually with a refundable deposit, the contractor's insurance, and set working hours. This is separate from and stricter than the HDB process, and approval takes time, so apply early and build it into the schedule.

Is renovating a condo more expensive than an HDB?

Not automatically. A new condo often comes with decent flooring, sanitaryware and sometimes wardrobes, so there is less to hack and redo than a resale HDB. The budget shifts from wet works and flooring toward carpentry, window dressing for tall glass, lighting and loose furniture. A tired resale condo can cost as much as any full renovation.

Can I hack walls in a condo?

Not structural ones. Columns, beams and structural walls cannot be touched, and post-tension slabs limit where you can drill or core. Some newer condos also restrict floor hacking to protect waterproofing. Get the as-built plan and design around what must stay, rather than assuming a wall can come down.

Do new condos need much renovation?

Less than a new HDB. Developers hand over floors, bathrooms and a basic kitchen already finished, so the work is mostly adding storage and character: wardrobes, a TV feature, kitchen carpentry, curtains and lighting. Ripping out good developer finishes to redo them is usually wasted money.

Condo Interior Design in Singapore: A First-Owner Guide

Different rules, better starting finishes, and a different place for the money. Designing a condo well begins with knowing what you are allowed to touch.

Owners moving from an HDB to a condo often assume the renovation runs the same way, just with a bigger budget. It does not. The approvals go through the condo’s management rather than HDB, the building itself limits what you can move, and a new unit usually arrives with finishes an HDB never gives you. Design a condo well and you spend less undoing and more adding. The starting point is not a mood board, it is the house rules. For the ideas side, our guide to interior design styles for a first home applies to any tenure.

The rules HDB owners do not expect

Four surprises catch most first-time condo owners. Tap through them before you plan anything structural.

MCST approval

The rule: Renovations need the management’s sign-off, a refundable deposit, the contractor’s insurance, and set working hours.
Watch: Hours are stricter than HDB. Many condos bar noisy hacking on weekends and public holidays entirely.
Tip: Apply early and hand the schedule to your designer, so the approval does not become the thing that delays move-in.

Hacking and structure

The rule: Structural walls, columns and beams cannot be touched, and post-tension slabs limit where you can drill or core.
Watch: Some newer condos restrict floor hacking altogether to protect the waterproofing and the services below.
Tip: Get the as-built plan and design around what must stay, rather than assuming a wall can come down.

Wet areas

The rule: Kitchens and bathrooms keep their drainage and waterproofing points. Relocating a wet area is restricted, sometimes barred.
Watch: Moving wet works can void the developer’s warranty and the building’s waterproofing cover.
Tip: Leave the wet zones where they are and put the budget into finishes and carpentry instead.

Balcony

The rule: Balconies usually cannot be fully enclosed, and their tiles and railings often cannot change, since they read on the building facade.
Watch: An unauthorised enclosure can draw a rectification order from the MCST or the authorities.
Tip: Treat the balcony as an outdoor room: shade, planting and furniture, not walls.

Work with the developer finishes

A new condo hands you flooring, bathrooms and a basic kitchen already done, often in good marble, timber or quality tile. The instinct to rip it out and start fresh is usually a waste. Unless a finish is genuinely not to taste or poorly made, keep it and build on top: add the wardrobes, the TV wall, the kitchen carpentry and the soft furnishing that turn a handover unit into a home. The money you save by not redoing sound finishes is money for the pieces that actually change how the place feels.

In a new condo, the win is what you add, not what you tear out.

Where a condo budget goes

Because the shell arrives finished, the spend shifts compared to an HDB. Less goes on hacking and wet works, more on:

Carpentry. Wardrobes, a feature TV console, kitchen extensions and entry storage do most of the work in a condo.
Window dressing. Floor-to-ceiling glass is beautiful and expensive to dress. Budget properly for curtains or blinds; bare glass undoes the look.
Lighting. Developer lighting is basic. Layered, warm lighting is one of the cheapest ways to lift a handover unit.
Loose furniture. With the shell done, good furniture is where the personality comes from.

Whether you have a compact one-bedder that needs every piece to multitask, or a larger unit that needs warmth so it does not feel like a showflat, the method is the same: learn the rules, keep the good finishes, and spend where it shows.

A condo has its own rulebook.
