Your budget depends significantly on whether your home is a brand-new “blank canvas” or an older unit requiring a complete overhaul. Based on current 2026 market rates in Singapore, here are the realistic ranges:

• New BTO (4-Room): Expect to invest between $40,000 and $65,000. Since these units are new, your budget typically focuses on “finishing touches” like custom kitchen cabinetry, wardrobes, lighting, and vinyl flooring.
• Resale (4-Room): A realistic range is $55,000 to $85,000, though full transformations can exceed $100,000. Resale flats often require “invisible costs” before aesthetics begin—such as professional hacking, full electrical rewiring, and copper pipe replacement to meet modern safety standards.
