HDB Renovation Cost in Singapore (2026): Budget Breakdown by Flat Type & Style
If you are planning to renovate your HDB flat in 2026, start with this realistic cost benchmark:
The average HDB renovation cost in Singapore in 2026 ranges from $30,000 to $100,000, depending on flat size, interior design style, and material quality.
Smaller flats cost less due to reduced carpentry and flooring, while larger flats and luxury styles increase overall renovation expenses.
In this article, we will break down renovation costs clearly, without sugarcoating anything.
Quick Renovation Cost Guide
| Renovation Type | Typical Cost Range |
| 3-Room HDB | $30k–$50k |
| 4-Room HDB | $40k–$70k |
| 5-Room HDB | $60k–$100k |
| Kitchen Only | $15k–$35k |
| Bathroom Only | $8k–$18k per bathroom |
Renovation Cost by HDB Flat Type
Let’s break it down realistically.
3-Room HDB Renovation Cost
In Singapore, you can expect the cost of renovation for a 3-room HDB to be anywhere between $30,000 and $50,000.
Here is the breakdown:
- Carpentry usually costs around $12k – $20k
- Flooring usually costs around $4k – $8k
- Electrical can cost around $2k – $4k
This ThisMoodBoard project shows how a well-planned 3-room renovation can improve both function and visual appeal without wasting budget.
4-Room HDB Renovation Cost
A 4-room HDB is the most common flat type in Singapore. The typical renovation range for a 4-room HDB flat is around $40,000 – $70,000. Costs are higher because 4-room flats usually require more carpentry, more wardrobe units, and more flooring area.
One real 4-room project came in at $58,000. The homeowner wanted a premium kitchen, clean built-in wardrobes, and upgraded flooring. No hacking. No dramatic layout changes.
The key was discipline; once the design was approved, nothing changed in the middle. That’s what kept it within budget.
5-Room HDB Renovation Cost
The typical range for a 5-room HDB renovation is $60,000–$100,000. The larger size of a 5-room HDB increases renovation cost because it usually involves more carpentry, more floor area, more lighting points, and sometimes feature walls or concealed systems.
The average cost for a 5-room HDB renovation is $60,000, but even with moderate finishes, it is challenging to keep it within that budget.
Cost by Renovation Scope
Partial Renovation Cost (Living Room and Kitchen)
Most homeowners want to renovate some parts of their homes.
Usually, the kitchen and living room. A partial renovation covering only the kitchen and living room typically costs around $25,000–$45,000. Partial renovation is a good option for resale flats.
Basic Renovation
Price range $30,000–$45,000
- Standard laminates
- Minimal hacking
- Basic lighting
- Functional carpentry
- Vinyl flooring
Suitable for homeowners who are renting or just want simple upgrades in their apartment.
Mid-Range Renovation
Price range $45,000–$70,000
- Custom wardrobes
- Upgraded laminates
- Feature walls
- Better lighting design
- Moderate hacking
This tier is very common for 4-room flats.
Luxury Renovation
$70,000–$100,000
- Premium surfaces (quartz, sintered stone)
- Custom detailing
- Concealed systems
- Designer lighting
- High carpentry volume
Renovation Cost by Room
Kitchen Renovation Cost
A kitchen renovation alone usually costs about $15,000–$35,000.
This depends on:
- Cabinet size
- Plumbing relocation
- Appliance integration
- Countertop material
Kitchen carpentry takes up most of the cost. That can round up to around $8,000–$20,000.
Bathroom Renovation Cost
Renovating each bathroom in your HDB flat usually costs $8,000–$18,000.
This includes:
- Tiling
- Plumbing works
- Waterproofing
- Vanity cabinet
- Shower screen
Renovation Cost by Interior Design Style
Interior design style isn’t just about aesthetics; it’s about creating a comfortable, functional living area.
Here is a realistic 2026 cost estimate by style:
| Style | Cost Range |
| Scandinavian | $30k-$55k |
| Japandi | $40k-$70k |
| Minimalist | $35k-$60k |
| Industrial | $45k-$80k |
| Luxury | $60k-$100k |
You must bear in mind that Luxury costs more due to:
- Custom carpentry
- Premium materials
What Takes Up the Largest Share of Your Renovation Budget
If you ask what eats up most of the renovation cost, the answer is always the same.
Carpentry.
Custom carpentry work is expensive as kitchen cabinets alone cost around $8,000 – $20,000. Moreover, wardrobes cost around $3,000 – $8,000 each.
ThisMoodBoard carpentry example showcases how renovation can maximize space and create ample storage with custom carpentry.
Why HDB Renovation Costs Often Exceed Budget
Most homeowners get in trouble because they actually underestimate renovation costs by 20–30%. Why?
Mainly due to hidden costs or small additions.
Things like:
- Electrical rewiring
- Extra power points
- Material and finish selections
- Plumbing rerouting
- Custom carpentry adjustments
- Size of the flat
Individually, these items may not look expensive, but together they can add thousands to your renovation bill. And they add up really quickly.
Common Renovation Cost Mistakes
After working with different clients and observing numerous projects.
Here are some mistakes that homeowners make that increase their renovation costs:
-
Changing design mid-project:
This is a very costly decision.
Once work starts, any change to the project is very costly.
Because most of the time:
- Materials for the initial project have been ordered
- Labour has been scheduled.
Any change means changing plans, work schedules, and even materials.
If you are indecisive about the right interior design for your home, don’t just jump into any project!
Hold on, take your time, consult your designs.
- Discuss your needs
- Ask questions
- Check the portfolio before making any commitments.
2. Choosing the cheapest contractor
A low quote may look tempting, but it can also mean necessary items are excluded.
What’s considered cheap can suddenly become very expensive.
Ensure your renovation quote covers:
- All required materials
- Labour
- Miscellaneous items.
3. Following trends
Trends can get you in huge trouble.
And they become outdated too.
I have seen homeowners regret:
- Ultra-trendy walls
- Carpentry
- Excess storage
- Too much layout
- Harsh paint
Always go for a design that’s functional and can outlast trends, like in this image.
4. Not setting a clear scope.
Renovation shouldn’t begin as a rough draft or picture. Clarity won’t come once the work starts without costing you extra cash. Renovation prices are based on design scope.
Clearly outline and define your scope:
- Number of cabinets
- Types of laminate
- Lighting position
- Tile selection
Clarity at the beginning of the design will always protect your wallet.
5. Underestimating storage needs
This one doesn’t always increase cost immediately, but it increases regret. If you cut corners in carpentry to save money, you might move in and realize you don’t have enough storage space:
- There isn’t enough wardrobe space
- The kitchen lacks functional storage.
- Everyday items have nowhere to go.
You have to strike a balance. Doing carpentry work later, after moving, will cost you more money.
Renovation Cost-Saving Tips
If you genuinely want to control your renovation costs, these are the strategies that work in real projects.
These are the cost-control strategies that consistently work in real renovation projects:
- Reduce excessive custom carpentry
- Keep existing flooring if it’s still in good condition
- Avoid unnecessary hacking
- Finalise your design decisions early
Also, ensure you plan every budget and how it will be spent. I have seen clients save over $10,000 simply by planning everything before the renovation starts.
Sample Budget Breakdown from a ThisMoodBoard 4-Room HDB Project
One of our 4-room HDB renovation projects came in at approximately $58,000. The owner prioritised:

Here is a simplified breakdown of the renovation costs:
- Kitchen: $18k
- Wardrobes: $12k

Well-organized storage is worth every penny in a kitchen renovation project. At the end of it, you’ll look at your kitchen and be glad you spent the right amount to get a functional space.
