Why Renovation Costs Increased in 2026

Renovation costs in Singapore are higher in 2026 due to rising material costs, labour costs, and stricter project constraints for resale, condo, and landed properties.

Material costs have increased for carpentry boards, tiles, stone, glass, lighting, and imported fittings
Labour costs have gone up across demolition, tiling, plumbing, electrical, and carpentry trades
Supply chain delays still affect selected imported finishes and made-to-order items

What You’re Actually Paying For

Work Category	Typical Cost Range	% of Total Budget
Carpentry (built-ins, wardrobes, kitchen)	$8,000 – $30,000+	25–40%
Masonry / Tiling	$5,000 – $20,000	15–25%
Electrical Works	$3,000 – $12,000	8–15%
Plumbing	$2,000 – $8,000	5–10%
Painting	$1,500 – $5,000	5–8%
False Ceiling / Lighting	$2,000 – $8,000	5–10%
Flooring	$3,000 – $12,000	8–12%
Hacking / Demolition (resale)	$3,000 – $8,000	5–10%
Waterproofing	$1,500 – $5,000	3–5%

Resale vs BTO: Why the Price Gap Exists

Work Type	BTO	Resale
Hacking (tiles, walls)	Rarely needed	Usually required
Rewiring / electrical upgrade	Modern wiring, minimal	Often outdated, full rewire
Waterproofing (bathrooms)	HDB warranty covers 3 yrs	May be degraded, replacement needed
Plumbing	New pipes, minimal work	Old pipes, replacement common

Understanding Budget Tiers

Budget Tier: $25K–$45K

Functional and clean. Standard laminates, basic carpentry, no feature walls. Good for BTO owners with tight timelines.

Moderate Tier: $45K–$80K

Balanced quality. Better materials, more carpentry, feature lighting, some custom elements. Most common range for 4–5 room HDB.

Premium Tier: $80K–$150K+

Custom everything. Marble, solid wood joinery, full electrical upgrade, smart home elements, full ID design service.

Key Factors That Move Your Budget

Property type and age — BTO vs resale gap can be $10,000–$30,000
Scope of carpentry — typically 25–40% of total budget
Material selection — can shift total budget by 30% or more
Wet works (kitchen and bathrooms) — most expensive per sqft
Who you hire — ID firms typically add 15–30% over direct contractors
Electrical and power points — budget $80–$120 per additional point

Smart Budgeting Tips for 2026

Always get 3 itemised quotes — not to find the cheapest, but to understand market rate
Set aside 10–15% as contingency — especially for resale properties
Never compromise on electrical, waterproofing, or structural work
Lock material prices early to protect against mid-project increases
Plan for temporary housing if doing resale — typically $2,000–$3,500/month
Work with CaseTrust-accredited firms where possible

Frequently Asked Questions

How much does it cost to renovate a 4-room HDB in 2026?

A 4-room BTO renovation costs $40,300–$62,300. A 4-room resale renovation costs $55,700–$80,400 and can go higher with full infrastructure replacement.

Why is a resale HDB more expensive to renovate than a BTO?

Resale flats require demolition of old fixtures, retiling, rewiring, waterproofing repairs, and plumbing upgrades that BTO owners rarely need. These infrastructure costs add $12,000–$25,000 before any design element is selected.

Should I hire an interior designer or go direct to contractor?

ID firms typically add 15–30% to renovation costs in exchange for concept design, 3D rendering, and project management. Direct contractors now often provide 3D renders for $300–$500 per room. For complex resale flats, an ID often justifies the premium. For clear-vision BTO owners, going direct saves $8,000–$18,000.

How much contingency should I set aside?

Set aside 10–15% of your total renovation budget. For resale properties, lean toward 15%. Contingency is standard practice, not pessimism.
