HDB Renovation Timeline: What to Expect from Start to Finish
Renovating an HDB flat in Singapore can be both exciting and overwhelming. Whether you’re moving into a brand-new BTO or upgrading a resale unit, understanding the typical renovation timeline helps you plan better, reduce delays, and manage expectations. From initial planning to handover, this guide walks you through each stage of the process.
Week 1–2: Consultation and Concept Planning
Your renovation journey begins with meeting your interior designer or renovation contractor. This includes discussions on layout preferences, style themes, colour palettes, and budget. Site measurements are taken, and mood boards are created.
Once the scope is defined, you’ll receive 2D layout proposals and estimated quotations. At this point, you should review and finalise your desired materials and design direction.

Week 3–4: HDB Permit Applications and Detailed Drawings
After design confirmation, your contractor will submit the necessary renovation permits to HDB. This is essential if you’re hacking walls, replacing flooring, or changing windows.
While waiting for HDB approval (usually within a week), technical drawings and 3D renderings are finalised. You’ll also choose fittings, lighting, and furniture with your designer.
During this phase, order lead times and delivery schedules for materials are aligned with the upcoming renovation works.
Week 5–6: Demolition and Wet Works
Once HDB permits are approved, actual renovation begins. Demolition (hacking of walls, removal of old tiles or fixtures) is typically completed in 2–4 days.
This is followed by wet works, such as laying of tiles, screeding, and plumbing adjustments. Wet works are critical and take time to cure properly. Quality control is essential at this point to avoid water seepage or uneven flooring later.
Note: Noisy works are usually restricted to specific HDB-approved hours.
Week 7–8: Carpentry Measurement and Electrical Works
Once tiling is done, your contractor begins electrical wiring, installation of lighting points, switches, and power sockets. Air-conditioning piping is also installed at this stage.
Simultaneously, site measurements for custom carpentry (kitchen cabinets, wardrobes, etc.) are taken and sent to the workshop. Carpentry production may take 2–3 weeks depending on the complexity.

Week 9–10: Painting, Fixtures, and Carpentry Installation
Your walls are now ready for paint. Most HDB homeowners opt for emulsion-based paints for ease of maintenance. Once painting is completed, bathroom and kitchen fittings—such as sinks, taps, toilet bowls, and mirrors—are installed.
Carpentry works will be delivered and installed during this period. Expect some adjustments to be made on-site to ensure perfect alignment and fit.
Week 11–12: Final Touches and Handover
Once the major works are done, your home undergoes detailed cleaning. Final fixtures like lights, ceiling fans, curtain rods, and small fittings are installed.
Your designer or contractor will conduct a walkthrough with you to identify any touch-ups or defects. These are resolved within a few days, followed by the official handover.
At this stage, you can start moving in furniture and preparing to call your new space home.
