How Much Does a 4-Room HDB Renovation Really Cost in 2026?

BTO vs Resale: The Cost Gap 4-Room BTO: $30,000–$50,000 4-Room Resale: $40,000–$70,000 The gap exists because resale flats require demolition, rewiring, and plumbing work that BTOs simply don't need.

Where Most People Overspend Carpentry is the number one budget buster. Custom-built wardrobes, feature walls with hidden storage, walk-in closets, and platform beds with drawers add up fast. If budget is tight, consider a hybrid approach: built-in carpentry for the kitchen (where it matters most for function) and freestanding furniture from IKEA or Taobao for bedrooms.
