Proven Ways to Save Money
Smart Material Choices:
-
Flooring: Choose vinyl (S$4-8/sqft) over marble (S$10-20/sqft) - saves S$3,000-6,000
-
Cabinets: Use laminate instead of solid wood - saves 30-40%
-
Countertops: Pick quartz instead of marble - saves S$2,000-4,000
-
Fixtures: Select mid-range instead of designer brands - saves S$2,000-5,000
Keep What Works:
-
Retain existing flooring if it's in good condition (saves S$3,000-5,000)
-
Keep solid cabinet structures, update only doors and countertops (saves S$5,000-8,000)
-
Reuse doors and windows where possible (saves S$1,000-2,000)
-
Resurface instead of replacing good tiles (saves S$2,000-4,000)
Shop Smart:
-
Choose built-in furniture over custom loose pieces (better space use)
-
Buy modular, multi-functional items to reduce pieces needed
-
Purchase appliances during annual sales (Great Singapore Sale, 11.11, 12.12) - saves 20-40%
-
Consider display sets with minor imperfections at discounted prices
Renovate in Phases:
-
Phase 1: Complete essential rooms first (kitchen, bathrooms)
-
Phase 2: Living room and common areas
-
Phase 3: Bedrooms and aesthetic upgrades
-
Spread costs over 6-12 months to manage cash flow better
DIY What's Safe:
-
Painting (saves S$2,000-3,000 on labor)
-
Installing curtains and blinds
-
Assembling loose furniture
-
Basic décor and styling
-
Important: Never DIY electrical, plumbing, or structural work
