HDB Renovation Cost in Singapore (2026 Guide)

Planning to renovate your HDB flat in Singapore in 2026? Understanding the renovation cost is the first and most important step before starting your project. Renovation costs in Singapore vary depending on flat size, design requirements, material selection, and contractor expertise. Without proper planning, expenses can easily go beyond your expected budget.

For a typical HDB renovation, the cost usually ranges from SGD 20,000 to SGD 80,000 or more. A 3-room flat generally costs around SGD 20,000 to 40,000, while a 4-room unit may range from SGD 30,000 to 60,000. Larger 5-room flats or fully customized designs can exceed SGD 80,000 depending on the level of renovation and material quality.

Several key factors influence the total renovation cost. These include hacking and demolition work, flooring materials, carpentry for kitchen and wardrobes, electrical rewiring, plumbing upgrades, painting, and decorative finishes. Among these, carpentry and kitchen renovation usually take the largest portion of the budget.

The type of materials you choose also plays a major role. Budget-friendly options like laminate flooring and modular cabinets can significantly reduce costs, while premium materials such as solid wood, marble, or custom-built furniture will increase the overall budget. In addition, hiring an interior designer instead of a direct contractor may add design fees but offers better project management and aesthetic results.

To manage renovation costs effectively, proper planning is essential. Setting a clear budget, comparing multiple quotations, and prioritizing essential works can help avoid unnecessary expenses. It is also important to avoid frequent design changes during the renovation process, as they can lead to delays and extra costs.

On average, a full HDB renovation takes between 3 to 10 weeks depending on project complexity. Smaller upgrades may be completed faster, while full home transformations require more time for approval, construction, and finishing.

Renovating your HDB flat is a long-term investment in comfort and lifestyle. With the right planning, trusted contractor, and realistic budgeting, you can achieve a modern and functional home without overspending.
