5 Best Interior Designer Decorators in Singapore (2026)

Independently ranked by our review of ratings, reviews and reputation · How we chose

By Brad Smith, Home Services Expert · ✓ Data verified August 2026 · 8 min read

Picking one of the interior designer decorators in Singapore is less about square footage and more about trust: months of decisions on layout, materials, and budget handed to someone you may only meet a handful of times in person. Yangs Inspiration Design has logged 488 Google reviews on exactly that relationship, and every firm on this page rates 4.7 or higher.

Short answer: Yangs Inspiration Design leads on review volume (4.7 stars, 488 reviews), covering HDB, condo, and landed home design across a large team of individual designers. Goodman Interior and SG Interior Design both carry strong ratings near 5.0. Design and renovation cost in Singapore depends heavily on scope, so get a detailed, itemised quote before committing.

Our take: A capable firm with a strong track record overall, but given the one detailed complaint about carpentry-stage supervision, ask directly how site visits and installation checks are handled.

How we score

Every number on this page comes from public Google data as of the date shown, not opinion or payment. Rating is the firm’s live Google star average. Review volume shows how many clients have rated them, ranked against other Singapore interior design firms. Confidence weighs the rating by that volume. Recency reflects how recently clients are still leaving reviews. No business can pay to change these numbers.

How much does interior design cost in Singapore? (2026)

Design and renovation cost depends heavily on property type, scope, and material choices. This is general guidance on what drives price, not a quote from any specific firm on this page.

Serving all of Singapore

These firms operate island-wide across Singapore, serving HDB, condo, and landed properties. Searching for an interior designer near me? Every listing below shows a live phone number so you can reach the closest option fast.

What to ask before you hire an interior designer

Which specific designer will handle my project, and can I see their portfolio?
Is the firm CaseTrust-accredited and HDB-licensed?
Will the designer be on-site for key milestones like electrical and carpentry installation?
What’s the process for cost-saving suggestions versus material upgrades?
What’s the timeline, and what happens if it runs over?

Frequently asked questions

How did you choose these designers?

We started from every interior design and decorating firm in Singapore with a public Google presence, then ranked by rating, review volume, consistency, and recency. See How we score above.

Are these rankings paid?

No. Rankings come from the public Google data in the scorecard. A business can pay to be a Featured Partner, which adds a badge and top placement, but that never changes another business’s score or position on the underlying data.

How often is this updated?

The data carries a verified date (August 2026 on this page). We refresh listings periodically so ratings and review counts stay current.

What does CaseTrust accreditation mean?

CaseTrust accreditation signals a firm has met certain consumer-fairness standards in Singapore, including transparent pricing and dispute-resolution processes. Massing Design and Goodman Interior both hold this accreditation.

Which firm is best if I want the designer physically on-site during construction?

Omni Interior Design is specifically praised by reviewers for having designers present during major installation milestones like aircon and fixture work.

The bottom line

Yangs Inspiration Design is the safe default on Singapore’s deepest interior design review base, while Goodman Interior stands out for CaseTrust accreditation and consistently on-time delivery. Confirm which specific designer you’ll work with before signing, given how many of these firms run large design teams.
