How to choose an interior design firm in Singapore
Whichever firm you shortlist, check these four things first:
- Licensing and protection. The firm should be on HDB's Directory of Renovation Contractors and hold CaseTrust accreditation, so your deposit and the works are protected.
- A portfolio that matches your home. Look for finished projects of your property type (BTO, resale HDB, condo or landed) in the style you want.
- A clear, itemised quotation. Every line should be priced with the materials named, so you can compare firms like for like.
- Reviews and after-sales care. Read recent reviews for how the firm handled defects after handover. That is where good firms stand out.
