You can get the original floor plan for an HDB resale flat through HDB’s Purchase of Residential Floor Plan service if you need a copy. Start by checking the original floor plan shown for a flat listed on HDB’s Resale Flat Listing service, or ask the owner if they have the plan supplied with the flat. For a purchase through HDB’s floor plan service, use the exact address and unit number.
Take the plan to the viewing and compare it with what is there today. The plan gives you a reference layout. Measure the spaces you will use and flag any differences for follow-up, particularly if you expect to remove a wall or fit new cabinetry. Read HDB’s floor plan service guidance.
- Check the full address and unit before downloading or ordering a plan.
- Keep the original PDF and use a separate copy for viewing notes.
- Print at Actual Size if you need the original drawing scale.
- Measure important spaces on site before buying furniture or finalising works.

Get a copy for the exact flat
HDB’s Resale Flat Listing service includes the original floor plan in the flat details. If you need to order a copy through the floor plan service, have the address, contact details and a valid email ready. HDB lists the fee as $5 per plan including GST. If the plan is available immediately, HDB says you can download it after payment. Otherwise, it says it will process and email the plan within three working days. Keep the order reference for follow-up. See HDB’s information on finding a resale flat.
| What you want to check | How to use the plan |
|---|---|
| Whether the layout suits your family | Mark likely room uses and trace the path between them |
| Whether a desk or bed fits | Take a site measurement and allow for doors and drawers |
| Whether the layout differs from the original | Circle the differences and ask what work was done |
| Whether planned wall works can proceed | Ask your contractor to check HDB’s permit and assessment requirements |

Print to scale and measure on site
HDB says the PDF is on A4 at 1:100. At that scale, 1 cm on a correctly printed plan represents 1 m in the flat. Select Actual Size in the print settings. A printout scaled to fit the page can alter measurements.
At a viewing, measure the clear dimensions between finished surfaces and allow for skirting, pipes and built-in furniture. For example, a student planning a 120 cm desk also needs room for the chair to move and for a nearby wardrobe or door to open. Use the plan to shortlist positions, then check those clearances with a tape measure.

Ask about differences before committing to renovation
If the original plan shows a kitchen partition you cannot see today, ask the owner when it was removed and whether they have the relevant renovation records. If your own plans include wall demolition, ask your renovation contractor about HDB’s evaluation and permit requirements. HDB says the contractor must submit a floor plan showing proposed work with the electronic application for works that require the plan. Read HDB’s renovation permit guidance.

Frequently asked questions
Can I use a floor plan from a similar unit?
Use it to get a general sense of the layout. For decisions about dimensions or works, get the plan for your specific unit and check it on site.
Should I mark up the original PDF?
Save the original separately. Use a copy with the date and your notes so it remains clear which markings came from your viewing.
