Buying a brand-new BTO flat is one of the most exciting milestones for every Singaporean homeowner. However, the journey doesn’t stop once you collect your keys — it truly begins when you start planning your HDB renovation. Unfortunately, many first-time homeowners rush into decisions, overspend, or make mistakes that they regret later.
In this comprehensive guide, HDBGROUPRENO.SG PTE. LTD shares insider tips, renovation hacks, and common pitfalls to avoid, so you can transform your BTO into a dream home without breaking the bank.

🔑 Why Renovating Your BTO Flat Is Different from Resale Units
Unlike resale flats, a BTO unit is delivered bare-bones — plain cement floors, simple bathroom fittings, and standard doors. This means you get a blank canvas, but it also comes with limitations such as:
- 3-year restriction on hacking tiles in kitchens and bathrooms.
- Mandatory HDB renovation permits for hacking walls, electrical works, or plumbing.
- Strict renovation timings (no noisy works on Sundays/public holidays).
Understanding these rules helps you avoid fines, delays, and unnecessary costs.
💸 The Real Cost of BTO Renovation in 2025
Many new homeowners underestimate how much they’ll actually spend. On average:
| Flat Type | Basic Renovation (Minimal) | Standard Package | Full Renovation (Premium) |
|---|---|---|---|
| 3-Room BTO | $10,000 – $20,000 | $22,000 – $32,000 | $37,000 – $47,000 |
| 4-Room BTO | $17,000 – $27,000 | $30,000 – $42,000 | $47,000 – $62,000 |
| 5-Room BTO | $20,000 – $32,000 | $37,000 – $52,000 | $62,000 – $82,000 |
👉 These numbers vary depending on your materials, carpentry, design style, and whether you engage an ID firm or direct contractor like HDBGROUPRENO.SG.
💡 Pro Tip: Always buffer 10–15% extra for unexpected costs (e.g., concealed wiring upgrades, waterproofing, additional carpentry).
🚫 10 Costly BTO Renovation Mistakes to Avoid
1. Starting Renovation Without a Budget Plan
Many couples collect their keys and jump straight into design discussions without a financial framework. This often leads to overspending.
✅ Solution: Fix a budget cap first, then allocate it across carpentry, flooring, electrical, plumbing, and furnishings.
2. Ignoring HDB Rules and Permits
Some homeowners hire unlicensed contractors who ignore regulations. This can result in stop-work orders or hefty fines.
✅ Solution: Always engage a BCA-registered contractor. At HDBGROUPRENO.SG, all works comply with HDB requirements.
3. Over-Customization of Carpentry
While custom cabinets maximize storage, excessive carpentry can eat into your budget and reduce flexibility for future changes.
✅ Solution: Balance built-in storage with loose furniture.
4. Choosing Cheap Materials That Don’t Last
Low-cost laminates, flimsy tracks, and budget hinges may save money now but will fail within a few years.
✅ Solution: Opt for E0 low-formaldehyde boards, premium hinges, and durable countertop materials (quartz > laminate).
5. Not Planning Electrical & Lighting Early
Adding sockets or lighting points later can be messy and expensive.
✅ Solution: Work with your contractor to finalize electrical layout before carpentry fabrication.
6. Forgetting Space-Saving Design
A BTO flat isn’t large. Without proper space planning, your home may feel cramped.
✅ Solution: Consider sliding doors, Murphy beds, and multi-functional wardrobes.
7. Rushing Into Furniture & Appliance Purchases
Buying a sofa or fridge before confirming exact dimensions often leads to fit issues.
✅ Solution: Finalize your renovation measurements first, then shop.
8. Neglecting Ventilation & Natural Light
Some homeowners block windows with tall cabinets, making the home feel dark and stuffy.
✅ Solution: Keep airflow and daylight pathways open, add mirrors to enhance brightness.
9. Skipping Defect Checks Before Renovation
If you don’t check for HDB-provided defects, contractors may later blame HDB or charge you extra.
✅ Solution: Conduct a thorough defect inspection within the 7-day reporting period.
10. Hiring the Wrong Contractor
Choosing based on the cheapest quote often ends in regret.
✅ Solution: Engage a transparent, experienced, and accountable company like HDBGROUPRENO.SG PTE. LTD.
