Starry Homestead
Starry Homestead is a design-and-build studio covering HDB, condo and landed homes, with in-house renovation and custom carpentry. Its site claims CaseTrust Gold and nine straight Qanvast SuperTrust awards, and Hometrust lists it as HDB and BCA registered with very high scores, especially for customer service. Aggregator Google ratings are lower, around 3.8 to 4.0 across its showrooms. We couldn't verify a written complaint pattern, and it publishes no prices or packages.
Suits homeowners who want an accredited, well-reviewed full-service firm. Compare its Google ratings with its Hometrust score before committing.

Swiss Interior
Swiss Interior focuses on HDB and condo projects and says it was founded in 2012, with HDB-registered renovation contractor status since 2014, CaseTrust since 2018, bizSAFE 3 and SIDAC accreditation. It offers space planning, 3D drawings, quotations, project management and after-sales support for minor fixes. Aggregator pages show high ratings, about 4.8 on Google and about 4.78 from 244 reviews on Qanvast. Its own figures for years in business are inconsistent, and no warranty terms are published.
A good fit for HDB and condo owners who want an accredited mid-range firm with many reviews. Ask for written warranty terms, as none are published.

Posh Living Interior Design
Posh Living does interior design and renovation for HDB, condo, terrace and landed homes, with showrooms in Ubi and Jurong East. Its site says it was established in 2013 but also claims over 20 years of experience, so its history is unclear. It advertises a deposit money-back guarantee bonded by NTUC Income and typical timelines of 6 to 12 weeks. CaseTrust and BCA aren't mentioned on the site. Google reviews on an aggregator average about 4.4 from 36 reviews, praising detail and service.
Suits budget-to-mid-range owners who value deposit protection. Verify its licences and CaseTrust status yourself before signing.

The Orange Cube
The Orange Cube is a design-and-build firm focused on landed homes, additions and alterations, rebuilds and 3D renders, operating since 2002 and taking only a few projects a year. Its site says it is a BCA-licensed GCB builder, but doesn't mention CaseTrust, HDB registration or warranty. An aggregator shows a Google rating of 3.8 from 20 reviews, and its homepage shows three positive testimonials. We couldn't verify a complaint pattern.
Suits landed-home owners who need design plus additions and alterations submissions. It's a less obvious choice for small HDB jobs, so confirm warranty and payment terms in writing.

Vegas Interior Design
Vegas Interior Design is a long-running interior design and decorator firm covering landed, HDB, condo and commercial spaces, said to date from around 2000. Its homepage lists no CaseTrust or BCA accreditation and no warranty. An aggregator shows about 3.9 on 16 Google reviews and 7.3 out of 10 on three Hometrust reviews, praising meticulousness and service. The review volume is small, so the evidence is thin.
Worth a look if you want an established designer for landed or condo work. Ask for licences, references and a written contract first.

Livspace Singapore
Livspace is a large design-and-build platform with operations in Singapore. Qanvast shows 204 reviews and no accreditation tags, while Hometrust gives it about 5.8 out of 10 from roughly 106 reviews, with around 40% of homeowners not recommending it and workmanship, service and value all scoring near 5.5 to 5.8. The reviews we could see weren't itemised, so we can't point to specific complaints. We couldn't confirm Singapore pricing, warranty or payment terms.
Suits those who want a large, branded process with many past projects. Check recent reviews and contract terms closely, given the mixed Hometrust scores.

Frequently asked questions
Is an interior designer more expensive than hiring a contractor directly?
Usually yes, because design fees are often built into the renovation quote rather than shown separately. In return you get space planning, 3D drawings, material selection and project management. Swiss Interior's site gives a typical range of about $30,000 to $100,000 or more depending on size and scope. Ask every firm for an itemised quote so you can compare like for like.
Why should I look for CaseTrust accreditation?
CaseTrust-accredited renovation firms commit to fair business practices, may offer prepayment protection, and can use the CaseTrust Standard Renovation Contract for price transparency. It isn't compulsory, so check each firm's status on the CASE website rather than relying on its own marketing.
Do HDB flats need approval for renovation works?
Yes, for certain works such as wall hacking and wet-area changes, which need prior HDB approval. Check that your firm is HDB-registered and who submits permits. Timelines quoted on firm sites are typically 6 to 12 weeks, though scope and approvals vary.
How should I protect my deposit?
Prefer firms with prepayment protection such as CaseTrust, or a bonded deposit guarantee. Posh Living advertises a deposit money-back guarantee bonded by NTUC Income, which we could only confirm from its own site. Tie the payment schedule to completed milestones in a written contract, and avoid paying large sums upfront to firms you can't verify.
Before you book
Prices and ratings change. Verify HDB and BCA registration and CaseTrust status on the official registers, and get an itemised quote and a milestone-based payment schedule in writing. Visit a completed project or speak to a recent client before paying a deposit.
