What to look for in a HDB interior designer
- An HDB-registered renovation contractor, because only registered contractors can apply for HDB renovation permits.
- Portfolios of flats the same size as yours, so the storage and layout ideas are proven in your floor plan.
- A clear plan for permits and working-hour rules. Read our HDB renovation permit and rules guide.
- CaseTrust accreditation for a standard contract and deposit protection.
- An itemised quote with materials specified.
