Understanding Renovation Budget Basics
A renovation budget is your total financial plan for home improvements, covering materials, labor, permits, and contingencies. In Singapore, where space is premium, poor planning leads to 20-30% overruns.[2]
Key components include carpentry (30-40% of budget), flooring (20-25%), and wet works like kitchens and bathrooms. Homejourney's verified resources help you allocate funds wisely for user safety and trust.[1]
Why Budget Planning Matters: It prevents debt traps, ensures HDB compliance, and aligns with lifestyle needs. For 2026, factor in 5-10% inflation on materials.[3]
Types of Renovations
- Basic: Painting, minor flooring – S$12,000-S$18,000.
- Standard: Full kitchen/bath – S$20,000-S$35,000.
- Premium: Custom designs – S$40,000+.[1]
Singapore-Specific Factors Affecting Renovation Costs
