From key collection to move-in — what actually happens week by week, and where most projects lose two weeks they didn’t plan for.
Most BTO owners walk in with a six-month picture in their head: collect keys, three months of building, two months of furniture and snags, move in. In our last 40 handovers, that’s almost never how it plays out.
What the timeline actually looks like
The shape we see most often is closer to six and a half months from key collection to housewarming — but only if approvals run clean and the carpentry shop isn’t doing four other jobs in the same week. Here’s the realistic breakdown.
Weeks 1–2: Defects inspection, HDB submission, finalisation of 3D renders.
Weeks 3–8: Hacking, tiling, electrical, false ceiling, plumbing.
Weeks 9–14: Carpentry, painting, fixtures, lighting install.
Weeks 15–18: Furniture, soft furnishings, snags.
Add those up and it is about four and a half months of work on site when every stage runs clean. That is the floor, not the forecast, which is why the realistic figure is longer and why we plan a buffer from the start.
Before you collect your keys
You can do more before key collection than most owners realise. The design does not need access to the flat: with your floor plan, the layout, carpentry, lighting plan and 3D renders can all be worked out in advance, so Week 1 starts with decisions already made instead of a blank page.
Choose your contractor early too. HDB only allows renovation in its flats by contractors listed in its Directory of Renovation Contractors, and for works that need a permit, your contractor applies to HDB on your behalf. The permit cannot be filed until you have appointed someone, so a late choice pushes back every week that follows. Dots ‘N’ Tots is an HDB Registered Licensed Contractor.
The HDB rules that shape the schedule
Three rules decide more of your timeline than any contractor does.
Working hours. General renovation works are allowed from 9am to 6pm on weekdays and Saturdays. Noisy works — hacking, removing wall or floor finishes, cutting tiles, heavy drilling — are limited to 9am to 5pm on weekdays only. No renovation is allowed on Sundays and public holidays.
Permits. Works that need HDB approval can only start once the permit is granted, which is why Weeks 1–2 are paperwork rather than hammers.
New-flat bathrooms. Newly built flats have a three-year restriction on removing the wall and floor finishes in bathrooms and toilets. If a new look for the bathroom is part of your plan, it has to be designed around the existing finishes from day one, not discovered on site.

The two weeks nobody plans for
The two-week buffer we mentioned earlier almost always gets eaten by one of three things: a delivery delay on imported tiles, a custom carpentry detail that the shop misreads on the first pass, or a defect from the BTO handover that wasn’t visible on inspection day.
Used right, the timeline is forgiving. Rushed, it’s brutal. The studios who consistently deliver clean handovers aren’t faster — they’re better at saying “this can wait two weeks” without losing the owner’s trust.
