This is the earliest — and best — time to start.

If you are planning a BTO renovation package in Singapore, this is when you decide how much carpentry and feature work you truly need.

Key actions:
At this stage, you should already have a rough layout plan and renovation priorities.
Tip: Avoid choosing solely based on the cheapest quotation. Look for clarity, experience, and realistic timelines.
2–3 Months Before Key Collection: Design Finalisation & Approvals
This phase is critical for keeping your renovation on schedule.
What happens here:
For resale renovation in Singapore, additional site inspections may be required to assess existing conditions.
Delays at this stage often lead to postponed renovation start dates.
1–2 Months Before Key Collection: Carpentry Fabrication & Ordering
Once designs are confirmed, fabrication begins.
Typical activities:
This step is crucial for homeowners opting for kitchen renovation packages, bathroom renovation packages, or HDB renovation packages with extensive carpentry.
Key Collection Month: Renovation Works Begin
Once keys are collected, renovation works can officially start.
Typical sequence:
BTO renovations usually progress faster due to the absence of hacking.
Flat Type | When to Start Planning | Typical Renovation Duration |
|---|---|---|
BTO Renovation Singapore | 3–4 months before keys | 6–8 weeks |
Resale Renovation Singapore | 4–6 months before keys | 8–12 weeks |
