Renovating a condo in Singapore typically costs between S$30,000 and S$80,000 depending on unit size, finishes, and scope of work. A standard 3-bedroom condo renovation averages S$50,000 to S$65,000. Your budget should cover interior design fees, carpentry, materials, electrical work, lighting, hacking, and labour. Understanding each cost category helps prevent overspending and hidden surprises.
If you are planning a condominium interior design Singapore project, the biggest mistake is treating renovation as one lump sum. Each trade has its own pricing structure. Once you know where the money actually goes, you can prioritise smarter and negotiate better.
Interior Designer Fees: What Are You Actually Paying For?
Interior designer cost in Singapore typically ranges from S$3,000 to S$15,000 for a condo project, depending on the scope of design work. Some firms charge a flat fee, others bill as a percentage of total renovation cost — usually 10% to 15%.
What this covers:
- Concept development and space planning
- 3D renders and material mood boards
- Contractor coordination and project management
- Site supervision throughout the renovation
Hiring a qualified interior designer is not just about aesthetics. A good ID catches structural conflicts early, manages timelines, and prevents costly rework. For a condo renovation, that oversight pays for itself.
Carpentry Costs: Usually the Biggest Line Item
Carpentry consistently takes up the largest share of a condo renovation budget — often 30% to 45% of total spend. For a 3-bedroom condo, carpentry alone can run from S$15,000 to S$35,000.
What Drives Carpentry Costs Up?
Custom built-ins cost significantly more than modular alternatives. A full kitchen cabinet set runs S$8,000 to S$18,000. A master bedroom wardrobe with full-height panels ranges from S$3,500 to S$7,000. Feature walls with integrated joinery add another S$2,000 to S$6,000.
Material choices matter too. Laminate finishes are more affordable. Veneer, lacquer, and solid wood finishes push costs higher. Most designers recommend laminate for utility areas and premium finishes only where they are visually prominent.
Hacking and Civil Works: The Hidden Foundation Cost
Before anything looks beautiful, old structures must come down. Hacking, screed, and tiling typically cost S$5,000 to S$12,000 for a standard condo unit. This covers removal of existing tiles, wall hacking for open-plan reconfigurations, and cement screed for new flooring.
Condo renovations are governed by Management Corporation Strata Title (MCST) rules. Most MCSTsmandate quiet hours, debris disposal protocols, and require approval for structural changes. Non-compliance leads to fines or work stoppages — always check your condo’s house rules before confirming the hacking scope.
Flooring Costs: Material Choices Define the Price Gap
Flooring for a 1,000 to 1,200 sq ft condo ranges from S$4,000 to S$12,000 depending entirely on material selection.
| Flooring Type | Estimated Cost per sq ft | Best For |
|---|---|---|
| Vinyl Plank | S$3 – S$6 | Bedrooms, budget builds |
| Porcelain Tiles | S$4 – S$9 | Living areas, wet zones |
| Engineered Timber | S$7 – S$14 | Living rooms, premium feel |
| Marble / Natural Stone | S$15 – S$30+ | Luxury finishes |
Porcelain tiles remain the most popular choice in Singapore condos — durable, easy to maintain, and widely available in formats that mimic natural materials at a fraction of the cost.
Electrical and Aircon Works: Non-Negotiable Budget Items
Electrical rewiring for a condo unit costs between S$3,000 and S$8,000. This covers additional power points, lighting circuits, feature wall wiring, and compliance with SP Group requirements. Do not cut corners here — faulty electrical work creates safety hazards and fails HDB or BCA inspections.
Air conditioning installation or replacement adds another S$3,000 to S$6,000 for a standard 3-bedroom unit with a multi-split system. Reputable brands serviced by licensed electricians and BCA-registered contractors should always be prioritised.
Lighting Budget: Often Underestimated
Lighting is frequently treated as an afterthought, then rushed at the end when the budget is thin. A proper lighting plan for a condo — combining recessed downlights, cove lighting, and pendant fixtures — costs S$2,500 to S$6,000 including installation.
Layered lighting transforms how a space feels. Ambient, task, and accent lighting each serve a different purpose. Skimping here visually flattens an otherwise well-designed interior. Allocate at least S$3,000 if the design concept relies on atmosphere and mood.
Painting and Finishing: Lower Cost, High Visual Impact
Painting a full condo unit costs S$1,500 to S$3,500 depending on ceiling height, number of coats, and paint brand. Premium paints with anti-mould or low-VOC properties cost slightly more but perform better in Singapore’s humidity.
Feature wall treatments — plaster finishes, fluted panels, or wallpaper — add S$800 to S$3,000 per wall depending on material. These are high-impact additions that anchor the design without dramatically inflating the overall condo renovation budget.
Condo Design Price Summary: Realistic Budget Breakdown
Here is a realistic budget allocation for a 3-bedroom condo renovation in Singapore:
| Cost Category | Estimated Range (SGD) |
|---|---|
| Interior Design Fees | S$3,000 – S$15,000 |
| Carpentry | S$15,000 – S$35,000 |
| Hacking and Civil Works | S$5,000 – S$12,000 |
| Flooring | S$4,000 – S$12,000 |
| Electrical Works | S$3,000 – S$8,000 |
| Air Conditioning | S$3,000 – S$6,000 |
| Lighting | S$2,500 – S$6,000 |
| Painting and Finishing | S$1,500 – S$3,500 |
| Total Estimated Range | S$37,000 – S$97,500 |
Keep a 10% to 15% contingency buffer on top of your approved budget. Unexpected hacking discoveries, tile pattern mismatches, or delivery delays are common and add up fast.
Where to Spend More — and Where to Pull Back
Spend More On:
- Carpentry — quality joinery lasts decades and anchors the whole design
- Electrical works — safety and future-proofing matter more than savings
- Flooring in high-traffic areas — durability saves money long-term
Pull Back On:
- Decorative accessories — these can be upgraded over time
- Wallpaper in humid zones — paint performs better in Singapore’s climate
- Over-customising guest rooms rarely used

Frequently Asked Questions
What is the average condo renovation cost in Singapore?
A standard 3-bedroom condo renovation in Singapore costs between S$50,000 and S$70,000. Costs vary based on unit size, design complexity, material quality, and whether structural hacking is involved. Always include a 10–15% contingency buffer in your condo renovation budget for unexpected expenses.
How much do interior designers charge for a condo in Singapore?
Interior designer cost in Singapore for a condo project typically ranges from S$3,000 to S$15,000. Some charge a flat project fee, while others bill a percentage — usually 10% to 15% — of total renovation costs. The fee covers design, project management, and site supervision.
What takes up the most of a condo renovation budget?
Carpentry is consistently the largest cost in condo design price breakdowns, often accounting for 30% to 45% of the total budget. Custom built-ins, kitchen cabinets, and wardrobe systems drive this figure. Material choices — laminate vs. lacquer vs. veneer — significantly affect the final cost.
Do I need MCST approval before renovating my condo?
Yes. Most condominiums in Singapore require MCST approval before renovation works begin, especially for hacking, plumbing, or structural changes. Your contractor or interior designer should handle permit submissions. Non-compliance can result in fines or forced reinstatement of original finishes.
Can I renovate a condo on a S$30,000 budget?
A S$30,000 budget is workable for a 1 to 2-bedroom condo with selective renovations — focusing on carpentry, painting, and flooring while retaining existing electrical and wet area layouts. Prioritise high-visibility areas and avoid full hacking to stay within the condo renovation budget.
Is condo interior design in Singapore more expensive than HDB renovation?
Condo interior design Singapore projects often cost more than HDB renovations due to higher material expectations, premium finishes, and stricter MCST guidelines. However, condo units typically allow more design freedom. The price gap narrows when HDB renovations involve extensive carpentry and full-unit reconfigurations.
