HDB renovation cost refers to the total expense required to design, upgrade, and customise a flat, including labour, materials, and installation.
The cost varies due to five main factors:
3-room: Lower cost due to smaller area
4-room: Most common, moderate cost
5-room: Higher cost due to scale and complexity
Basic: Cosmetic upgrades (painting, lighting)
Mid-range: Includes carpentry and tiling
Premium: Full redesign with structural changes
Material choices significantly impact cost:
Laminate vs solid surfaces
Quartz vs sintered stone countertops
Standard vs premium fittings
For kitchens, choosing durable solutions like aluminium kitchen cabinets can support easier aluminium maintenance, reducing long-term upkeep costs compared to wood-based options.
Built-in wardrobes, TV consoles, and storage solutions increase costs but improve usability and space efficiency.
BTO Flats
Lower cost
Minimal hacking required
Focus on carpentry and finishes
Resale Flats
Higher cost
Requires demolition, rewiring, plumbing updates
Resale flats often come with older layouts, worn finishes, and outdated systems that need to be replaced before new work can begin. This increases both labour and material costs, especially when hacking, rewiring, and waterproofing are involved.
