Frequently Asked Questions
How much does a full 4 room HDB renovation cost in Singapore?
A full 4 room HDB renovation in Singapore typically costs between S$35,000 and S$100,000 depending on scope, material choices, and whether the flat is a new BTO or resale. The average for a standard renovation with custom carpentry and bathroom upgrades is around S$55,000 – S$70,000.
How long does a 4 room HDB renovation take?
Based on our completed 4-room HDB projects, renovations typically take 2 to 5 months. A standard renovation with carpentry and tiling work averages 3 months. Larger scope projects or resale flats with extensive hacking can take up to 5 months.
Is it cheaper to renovate a BTO or resale 4-room HDB?
BTO flats are generally cheaper to renovate as the structure is new, hacking requirements are minimal, and there are no old fixtures to remove. Resale renovations often require more demolition work, which adds S$5,000 – S$15,000 to the total cost.
What is included in a 4 room HDB renovation package?
