Renovation budgets almost always run over. According to industry surveys, more than 70% of homeowners spend more than they initially planned. The reason isn’t usually dishonest contractors — it’s poor planning at the start.
The Real Cost Breakdown
For a typical 4-room HDB full renovation, here’s roughly where the money goes:
- Hacking & disposal: S$2,000–S$5,000
- Flooring: S$5,000–S$15,000
- Kitchen: S$8,000–S$20,000
- Bathrooms: S$5,000–S$12,000 each
- Carpentry: S$10,000–S$25,000
- Painting: S$2,000–S$5,000
- False ceilings & lighting: S$3,000–S$8,000
What People Always Forget
- Curtains and blinds (S$1,500–S$5,000)
- Aircon installation or replacement
- Appliances (fridge, washer, hob, hood)
- Furniture after renovation
- Temporary accommodation during works
Contingency Rule
Always keep 10–15% of your total budget unallocated. When hacking starts, surprises happen — hidden pipes, uneven floors, old wiring that needs replacing. Having contingency means these don’t become crises.
