How Much Does it Cost to renovate a 5-Room HDB?

12 Aug 2022

If you’re planning to spend a lot on your HDB renovation, this post is for you. We’ve put together a comprehensive list of all the costs involved in getting your entire home redone from top to bottom. Whether you’re looking to completely gut your place or want to just give the rooms a fresh coat of paint, this article will break down the total cost of the entire project, including all the big expenses and the small stuff.

How much can you expect a 5-room HDB flat renovation to cost?

BTO flat type Expected median renovation cost in 2022
3-room flat $35,000 to $38,000
4-room flat $40,000 to $46,000
5-room flat $47,000 to $56,000


Homeowners may anticipate spending around $35,000 to $38,000 repairing a brand-new 3-room BTO flat, $40,000 to $46,000 for a 4-room BTO flat, and $47,000 to $56,000 on a 5-room BTO flat in 2022, according to median renovation cost data compiled from over 200 BTO flat projects finished in 2021. 

Except for 5-room units, 2021’s median prices show a minor to moderate decline in renovation spending on BTO flats compared to the past; this trend may be explained by new homeowners’ more frugal spending habits and a decline in purchasing power due to inflationary considerations.

How much can you expect a resale 5-room HDB flat renovation to cost?

HDB flat type Expected median renovation cost in 2022
3-room flat $40,000 to $50,000
4-room flat $50,000 to $58,000
5-room flat $68,000 to $80,000


Homeowners of resale HDB flats had to spend more on renovations in 2021 due to higher material costs and increased labor costs, which suggests that they will also have to spend more in 2022. 

The average 3-room resale apartment renovation will cost between $40,000 and $50,000 this year, according to median pricing from over 400 HDB resale flat projects finished in 2021. Accordingly, the typical expenses for remodeling 4- and 5-room resale units in 2022 are probably going to fall between $50,000 and $58,000 and $68,000 and $80,000, respectively.

What other factors impact the cost of your renovation?

We’ve talked about how the amount of carpentry, masonry, and hacking required for a renovation project can drive up the 4 room HDB renovation cost. Your choice of finishes and materials for your walls, floors, and other surfaces, such as kitchen counters, is a further significant consideration to save on renovation costs in Singapore. 

Plastering, skim coating, painting, and tiling are some of the floor and wall finishing options. Waterproofing is also required in moist places like the kitchen and bathroom. Your choice of wall and floor tiles can cause renovation expenses to soar, so they must be taken into account independently in your budget.

Vinyl $3 to $8 psf
Laminate $2 to $8 psf 
Ceramic tiles $3 to $35 psf (including labour)
Cement screed (polished) $15 to $30 psf

How long will it take to renovate a new 5-room HDB flat?

BTO apartment owners will likewise have to wait a little longer for their flats to be finished in 2022 if 2021 is any indication. Last year, the median time to complete renovations for 3- and 4-room BTO flats was 8 to 9 weeks, and 5-room BTO flats needed 8 to 10 weeks. This results in an increase of 2 to 4 weeks in 2021 compared to the pre-COVID years, depending on unit size.

How long will it take to renovate a resale 5-room HDB flat?

For the same market-related reasons as BTO flat renovations, resale HDB apartment makeovers are projected to take longer to complete in 2022. For a 3-room resale HDB flat, you may anticipate a wait time of 8 to 9 weeks, for 4-room resale units, of 8 to 10 weeks, and for 5-room resale flats, of 9 to 11 weeks.

How to locate a trustworthy remodeling contractor in Singapore?

Beware of renovation scams before you rush out to choose a firm to hire. Plenty of people are waiting to take advantage of trusting homeowners. In addition to checking references and avoiding deals that seem too good to be true, confirm that the company is authentic. 

While you may verify if an ID is CaseTrust accredited for IDs, HDB maintains a list of approved renovation contractor Singapore and merchants. 

Only contractors listed in the Registered Renovation Contractors’ Scheme may be used if you’re remodeling a HDB apartment (RRCS). HDB-approved contractors are aware of all HDB regulations and will decline work that does not adhere to them.

As HDB doesn’t perform any renovation work, they don’t have a roster of interior designers. The ID firm collects your deposit and vanishes, which is the scene of many renovation frauds. 

Use only ID companies that have received CaseTrust accreditation to protect yourself. The certification program mandates that businesses get a deposit performance bond to safeguard their customers’ deposit payments. You won’t lose your deposit if the business goes out of business before the job is completed.
