Renovation cost guide

How much does renovation cost in Singapore in 2026?

Renovation prices in Singapore vary widely because no two homes start from the same place. These are the four factors that move your budget the most.

1. Size and type of your home

A 3-room HDB flat has less floor area, less wall area and fewer rooms than a 5-room flat or a condo, so almost every trade costs less. Landed homes sit at the top of the range because of their sheer size and structural complexity.

2. New unit or resale

Resale units usually need hacking, dismantling and making good before new works can begin. A resale renovation of the same scope typically costs 10 to 20 percent more than the equivalent BTO project.

3. Scope of works

Wet works are the big-ticket items. Bathrooms and kitchens involve hacking, waterproofing, tiling, plumbing and carpentry all at once, which is why a full renovation costs several times more than a cosmetic refresh of paint and flooring.

4. Materials and finish level

The same wardrobe can be built in laminate or in fluted, spray-painted panels with internal lighting. Countertops range from laminate to quartz to sintered stone. Finish level is the easiest lever to adjust if your estimate comes in above budget, and your designer can show you exactly where to save.

Questions, answered

Renovation estimate FAQ

How accurate is this renovation cost estimate? +
The ranges are calibrated against recent itemised quotations we prepared for Dreamakers clients, so they reflect what we actually charge rather than generic internet averages. It is still a planning guide, not a binding quote. After a free consultation and site assessment, we prepare a detailed, line-by-line quotation, usually within about a week of your consultation.
Is the calculator free to use? +
Yes, completely free, with no sign-up and no contact details required to see your estimate, and no obligation to engage us afterwards. We built it so homeowners can plan their budget with realistic numbers before speaking to any interior design firm.
How much does it cost to renovate a 4-room HDB flat? +
In 2026, a light refresh of a 4-room flat typically starts from around S$25,000 to S$40,000, while a full renovation of a resale unit commonly runs from S$45,000 to S$80,000 or more, depending on hacking, carpentry, materials and finish level.
What affects renovation cost the most? +
The size and condition of your home, how much hacking and wet works are involved, the amount of custom carpentry, and your choice of materials and finishes. Resale units usually cost more than new BTO flats because of the additional dismantling and preparation work.
Is the estimate binding? Do I need to pay anything? +
No. The estimate is free and not binding on you or us. If you decide to proceed, Dreamakers Interior is CaseTrust accredited, which means your deposit and project timeline are protected under Singapore's renovation standard.
