Singapore Renovation Costs 2026: The Ultimate Budgeting Hub
Planning your home renovation in 2026? Uncover realistic cost breakdowns for BTOs, resale HDBs, and condos, plus financing constraints.
Last updated: 7 Mar 2026
Transforming a bare concrete unit or an aging resale flat into your dream home requires a robust understanding of current pricing baselines and financing constraints.
This 2026 guide serves as the definitive budget and cost-planning hub, expanding on realistic budget ranges, room-by-room breakdowns, and how to spot hidden traps in Interior Design (ID) quotes.
(Note: Regulatory limits heavily impact your costs. Before planning a demolition, you must cross-reference our dedicated HDB Renovation Rules & Permits Playbook to ensure your design is legally compliant.)
1. Average Renovation Costs in Singapore (2026 Baseline)
Renovation costs vary drastically based on property type, size, and the extent of the overhaul.
- HDB BTO (New): $20,000 – $40,000+ BTO flats come as a blank canvas. Because you rarely need to hack existing infrastructure, the bulk of your budget goes directly into aesthetics: custom carpentry and vinyl flooring overlays.
- Resale HDB: $60,000 – $90,000+ Older flats require a "rip and replace" approach. You pay to demolish first, followed by mandatory replacement of aging electrical wiring (essential for flats over 20 years old) and full replumbing.
- New Launch Condo: $15,000 – $35,000+ Developers usually provide fully fitted units. Costs are mostly isolated to customized feature walls, smart home integrations, ambient lighting, and minor carpentry.
- Resale Condo: $70,000 – $120,000+ Similar to resale HDBs, but condo renovations carry a "private property premium" due to strict MCST rules, shorter working hours, and complex debris disposal logistics.
2. Cost Ranges by Common Unit Sizes
Budgeting by flat type gives a clearer baseline.
| Property Type & Size | BTO / New Launch (Light to Medium Scope) | Resale (Heavy Overhaul / Gut Reno) |
|---|---|---|
| 3-Room HDB (~65-70 sqm) | $18,000 – $28,000 | $45,000 – $65,000 |
| 4-Room HDB (~90-95 sqm) | $22,000 – $35,000 | $60,000 – $85,000 |
| 5-Room HDB / EA (~110-130 sqm) | $28,000 – $45,000 | $75,000 – $110,000+ |
| Condo Small (1 to 2-Bedder) | $15,000 – $25,000 | $50,000 – $80,000 |
| Condo Family (3 to 4-Bedder) | $25,000 – $40,000 | $80,000 – $130,000+ |
3. Scenario Budgets: Real-World Examples
Scenario A: The "Lean & Clean" 4-Room BTO
Target: A young couple keeping HDB floors and bathroom tiles to save money. Estimated Total: $26,000
- Carpentry: $12,000 (Kitchen cabinets, master wardrobe).
- Electrical & Lighting: $3,500
- Masonry & Wet Works: $2,000 (Kitchen bases/shower kerbs).
- Miscellaneous: $8,500 (Vinyl overlay, plumbing fixtures, painting).
Scenario B: The "Gut & Rebuild" 4-Room Resale HDB
Target: A family purchasing a 25-year-old flat requiring a complete systems overhaul. Estimated Total: $82,000
- Demolition & Haulage: $6,500
- Masonry & Waterproofing: $18,000 (Screeding, laying new tiles, waterproofing).
- Carpentry: $22,000
- Systems (Plumbing/Electrical): $10,500 (Full replacement and rewiring).
- Windows, Doors & Misc: $25,000 (False ceilings, paint, air-con).
4. Room-by-Room Cost Breakdown (Data-Rich)
- Kitchen Custom Carpentry: $120 – $180 per foot run (pfr).
- Kitchen Countertops: $90 – $200+ pfr (Quartz is standard; Sintered stone is premium).
- Bathroom Full Hacking & Wet Works: $3,500 – $5,500 per bathroom.
- Living Room Vinyl Overlay: $4.50 – $6.50 per square foot (psf).
- False Ceilings: $4 to $7 psf of the ceiling area.
5. Financing Constraints & Loan Realities
- No CPF Ordinary Account (OA) for Renovation: You cannot use your CPF OA to pay your interior designer or contractor. Your renovation must be funded by cash or a specific bank loan.
- The Renovation Loan Cap: MAS regulations strictly cap bank renovation loans at a maximum of $30,000 or 6 times your monthly salary, whichever is lower.
- Direct Disbursement: Renovation loans are not deposited into your personal bank account. The bank issues cashier's orders directly to your main contractor based on their invoices.
6. Quote Comparison Framework & Audit Worksheet
Use this line-item audit worksheet when reviewing your ID quotes:
- Are payments progressive? (Red Flag: Asking for 50% upfront. Standard is 10-15% deposit).
- Is Haulage & Disposal included? (Disposal of debris at approved sites costs $500–$1,500+).
- Are material brands specified? (Look for specifics like "EDL/Lamitak laminates" instead of "premium laminates").
- Is Carpentry billed per foot run (pfr)? (Avoid lump-sum quotes for cabinets).
- Is GST included? (If the firm is GST-registered, an unexpected 9% addition at the end can break your budget).
7. Frequently Asked Questions (Budget & Cost)
1. Is GST usually included in renovation quotes? This varies widely. Always check the fine print at the bottom of the quotation. Many firms state prices excluding the prevailing Goods and Services Tax (GST).
2. What is a standard and safe payment schedule? A safe schedule is progressive: 10-15% upon signing, 30-40% upon hacking commencement, 30-40% upon carpentry fabrication, and the final 5-10% upon successful handover.
3. Are "Provisional Sums" in a quote safe? Provisional sums are placeholders for items you haven't selected yet (like lighting fixtures). They are standard but dangerous if underestimated. Audit them to ensure the allowed budget matches market reality.
4. How much budget buffer should I set aside? Always allocate a 15% to 20% contingency buffer on top of your quoted price, especially for resale flats where hidden issues (like spalling concrete) are common.
