HDB Renovation: what to keep when renoving an old flat
HDB Renovation on an old resale flat doesn't mean stripping everything to bare concrete. Smart owners keep what's still good and spend their budget where it counts. Holding onto solid tiles, workable doors, and sound fittings can shave thousands off the bill — money better used on carpentry and services. The trick is knowing what's worth retaining.
1. Check the existing tiles first
Original floor tiles in older flats are often thicker and tougher than today's thin ones, and many are still perfectly serviceable. If they're level, uncracked, and a colour you can live with, keep them. You save on hacking, new tiles, and the labour to relay them.
For a 4-room resale, keeping good living-room and bedroom tiles alone can save a meaningful chunk of a renovation budget that, based on recent market observations, typically ranges from S$50,000 to S$80,000 or more. Use the saved budget on built-in wardrobes or kitchen cabinets instead.
2. Doors and frames worth retaining
Solid timber or good-quality flush doors in an old flat often outlast the trendy replacements. If the hinges work and the frame is square, a fresh coat of paint or new handles can make them look current. Remember HDB restricts changes to the main door position and certain frames, so keeping internal doors also keeps you clear of permit issues.
- Repaint doors in a modern tone rather than replacing.
- Swap dated handles for sleek ones — a cheap refresh.
- Keep the bomb-shelter door untouched; it's regulated and must stay.
3. Built-in and service elements to leave alone
Some things should stay for practical and rule-based reasons:
- The bomb shelter — never hack or alter its structure.
- Floor traps and parapet walls — hacking them isn't allowed.
- Existing waterproofing that passes a test — leave it if it holds.
- Metal gates and grilles that are still secure — repaint instead of replace.
Keeping these avoids both legal trouble and needless spend. The renovation permit, valid three months from application after resale completion, won't cover works HDB forbids anyway.
4. Kitchen and bathroom calls
If the toilet tiles are sound and the layout works, you can keep them and just replace fittings — a new basin, shower set, and a fresh coat of semi-gloss mould-resistant paint. In the kitchen, cabinets might be dated but the floor and walls could be fine; reskinning doors or adding a new countertop sometimes beats a full tear-out.
That said, if waterproofing has failed or tiles are hollow, keep nothing there. Fix the source, don't preserve a problem.
5. What to always replace
Some items are false economies to keep. Old wiring that can't handle modern loads should be upgraded. Worn-out carpentry with sagging hinges is rarely worth saving. Stained, smelly ceiling boards belong in the bin. Spend there, save elsewhere — that balance is what keeps an old-flat reno sane.
Work only with a BCA-licensed contractor on HDB's Directory of Renovation Contractors so retained elements stay compliant and the deposit — S$1,000 for four rooms and up — comes back after inspection.
6. Making the kept and new blend
The hard part is making old and new look intentional. Choose new carpentry and paint tones that sit in the same family as what you kept, so the flat reads as one home, not a patchwork. This is where planning whole-house customization around your existing strengths pays off. Keep the good, replace the tired, and your old resale flat renovates beautifully without draining the budget.
