Renovating a brand-new BTO flat is an exciting milestone, but it’s also a significant financial commitment. In 2025, renovation costs have continued to rise, driven by inflation, higher material costs, and increased demand for skilled labour.
Here’s a brief breakdown of what you can expect to spend, and how you can plan your budget wisely.
Average Renovation Costs by Flat Type
| Flat Type | Typical Renovation Cost (2025)
|-----------|-------------------------------------
| 3-room | $34,200 – $52,100
| 4-room | $52,500 – $66,000
| 5-room | $62,000 – $70,000
These figures cover essential works such as flooring, carpentry, electrical wiring, painting, and basic fittings. The final cost depends on several factors: the size of your flat, the complexity of your design, the quality of materials, and whether you engage a contractor or an interior designer.
So what’s really costly?
l Built-in Carpentry: Custom wardrobes and kitchen cabinets are often the most expensive items.
l Premium Materials: Choosing marble countertops or designer tiles can quickly inflate your budget.
l Smart Home Features: Integrated lighting, automated blinds, and advanced appliances are popular but come at a premium.
l Labour and Project Management: Hiring a reputable interior designer for a full-suite service will cost more than managing contractors yourself.
Financing Your Renovation
Most homeowners use a mix of savings and renovation loans (up to $50,000). Renovation loans typically offer flexible repayment terms, but remember to factor in interest rates and your overall debt servicing ratio.
Money-Saving Tip: Consider HDB’s Optional Component Scheme (OCS) to get basic fittings like doors, tiles, and sanitary wares at a lower cost. This can help you save on initial renovation expenses, especially if you’re happy with standard finishes.
