HDB BTO vs Resale Renovation: Which Costs More in 2026?

BTO vs Resale: The Renovation Cost Difference One of the most common questions Singapore homeowners ask is whether renovating a BTO or a resale HDB flat costs more. The short answer: resale almost always costs more, but the gap depends on the age and condition of the resale unit. Why BTO Renovations Are Generally Cheaper BTO flats are brand new. The walls, floors, doors, and windows have not been used or modified by previous owners. You start from a blank canvas, which means you only pay for what you want to add, not for tearing out what was already there. Typical 4-room BTO renovation in 2026: $35,000 to $55,000 for a comfortable mid-range package. This usually covers carpentry, electrical work, painting, lighting, kitchen upgrades, and bathroom accessories. Hacking and demolition costs are minimal because most BTO buyers retain the existing layout. Removing a non-structural wall in a BTO might cost $400 to $800. Why Resale Renovations Cost More Resale flats often need overhauling. Older units may have outdated wiring, worn-out flooring, leaking bathrooms, and tired-looking kitchens. Many require full hacking before any new work can begin. Typical 4-room resale renovation in 2026: $55,000 to $90,000, and sometimes higher for flats over 30 years old. Common additional resale expenses: - Hacking and disposal: $3,000 to $8,000 - Complete bathroom overhaul including waterproofing: $7,000 to $12,000 per bathroom - Rewiring and upgrading the electrical distribution box: $2,500 to $5,000 - Replacing windows or main door: $1,500 to $4,000 - Asbestos checks for very old flats (pre-1980s) Hidden Costs to Watch For For resale, always budget a 10 to 15 percent contingency. Issues like hidden water damage, cracked tiles under existing flooring, or outdated plumbing only show up once work begins. For BTO, the main hidden cost is upgrading items that look fine but underperform, such as the developer-provided toilet bowl, basic kitchen tap, or default lighting. When Resale Can Be Cheaper Than BTO If you buy a resale flat that was recently renovated by the previous owner and the design suits your taste, you can move in with very minimal touch-up work. Some homeowners spend as little as $10,000 on a freshly renovated resale. Final Tip Always get at least 3 quotations and ask contractors to itemize their cost breakdown. A well-itemized quote helps you spot inflated charges and compare like for like.
