Our Methodology for Calculating Average Renovation Costs in Singapore We gather actual itemised renovation materials and labour costs from renovators in Singapore. Inflation has also been accounted for as these are based on current, real-world costs.
From there, we determine the realistic lower and upper renovation cost ranges by simulating logical scenarios based on the extensiveness of renovation cost components such as hacking, masonry, carpentry, plumbing, electrical, and common finishing works (air-conditioning, painting, partition, door, and window works).
Finally, we apply a reasonable mark-up of 15% to the renovation cost prices to reflect the standard industry profit margins for interior designers .
Why do Most Sources Provide Inaccurate Estimates of Renovation Costs? Most sources estimate costs based on the average or median renovation budgets derived from their user base or survey results.
This approach leads to inaccuracies due to confounding factors, such as:
1) Small Sample Size : Their user base may not be representative of the wider market.
2) Income Bias: For example, It is reasonable to assume that new condo homeowners typically have higher incomes and may be more willing to spend on renovations. Hence, if we solely rely on average or median historical data, it will only be reflective on spending habits rather than the true costs of materials and labour. Ultimately, it leads homeowners to believe that condo renovations are inherently more expensive, when in reality, they can often be more affordable (as detailed below in this article). Such misconceptions can lead homeowners to budget more than what is actually required for their renovation.
3) Variability of Renovators: Interior firms or even individual renovators from the same firm can charge at different price points based on their expertise and reputation e.g. a design-centric interior designer would charge higher professional fees as compared to a renovation main contractor. Simply averaging renovation costs from multiple renovators may lead to skewed results even if outliers are excluded.
4) Scope of Renovation: The scope of renovation projects can vary widely leading to significant differences in renovation costs. Simply taking the higher and lower percentiles of averages can be misrepresentative of actual renovation costs.
Our methodology avoids perception-based estimates and instead calculates fair and realistic prices grounded in actual material and supply costs.
This data-driven approach provides a clearer understanding of renovation expenses, eliminating the potential inaccuracies introduced by skewed averages or medians.

BTO Renovation Costs Based on our renovation cost estimates, a full renovation for a new HDB flat typically ranges from:
BTO Renovation Costs
BTO Renovation Costs
BTO Property Type
Typical Renovation Cost
HDB 2-Room
S$15,400 – S$31,600
HDB 3-Room
S$35,000 – S$55,000
HDB 4-Room
S$50,000 – S$70,000

HDB Maisonette

HDB Jumbo
S$101,000 – S$155,900
For a more detailed breakdown, you can refer to our HDB BTO and resale renovation costs in Singapore guide.
A BTO home renovation is generally the most affordable because new HDB flats are handed over with new walls, ceilings, electrical wiring, plumbing, and basic finishes already in place. Since there is little or no demolition work required, with minimal hacking needed in newer flats, homeowners can allocate more of their renovation budget towards customisation rather than repairs.
HDB BTO Interior Design by Forefront Interior Common BTO renovation works include:
Kitchen cabinets and countertops Built-in wardrobes and custom carpentry Laminate flooring or tile upgrades, with vinyl flooring as a cost-saving alternative False ceiling and cove lighting TV consoles and feature walls Painting Air conditioning installation Additional power points and basic lighting Smart home integration For aesthetic upgrades , painting walls is usually more budget-friendly than wallpapering or feature walls.
Why are BTO renovation costs generally lower? Because new HDB flats are delivered in good condition, homeowners usually do not need to budget for:
Hacking existing finishes Full electrical rewiring Plumbing replacement Waterproofing repairs Removal of existing built-in fixtures Extensive rectification works This allows a larger portion of the home renovation budget to be spent on interior design, furniture, appliances, and finishes instead of essential repair works.

This resale HDB renovation cost guide varies by flat type , age, and condition, and renovation costs in Singapore vary significantly by property type and age. A 4-room resale HDB can reach about S$85,000 at the upper end of current estimates. Resale flats often cost around 20% to 40% more to renovate than comparable new flats.
Why do resale renovation costs more? HDB Resale Interior Design by Starry Homestead A resale renovation generally costs more than renovating a new BTO because older flats often require additional construction work before renovation can begin. Depending on the property's condition, homeowners may need to replace ageing electrical wiring, plumbing, flooring, or waterproofing, and lingering water or electrical issues can raise costs sharply, all of which contribute to higher home renovation costs .
The biggest difference between a new BTO and a resale HDB is that older homes often require rectification works before the actual renovation can begin.
Renovation Work Differences between New BTO and Resale HDB
Renovation Work Differences between New BTO and Resale HDB:
Renovation Work
New BTO
Resale HDB
Hacking existing flooring and walls
Rarely required
Often required
Electrical rewiring

Plumbing replacement
Rare
Common in older resale flats
Bathroom waterproofing
Usually not required
Often recommended
Removal of existing cabinets and fixtures
Not required

Rectification works
Minimal
Common depending on the property's condition
These additional works can easily add thousands of dollars to the real cost of a house renovation , and hacking costs depend on wall size and thickness, which is why resale quotations are typically higher than those for comparable BTO flats, with structural changes and premium materials being two common reasons for higher costs .

While newer condominiums may only require cosmetic upgrades, older condos can involve rectification works similar to those found in resale HDB flats.
Homeowners should also budget for condominium-specific requirements such as MCST renovation deposits, administrative fees, renovation permits, and restrictions on working hours.

Not every "hidden cost" is necessarily unavoidable.
