If you are looking for the best interior design firm Singapore has in 2026, the honest starting point is that the right firm depends on what you are renovating. A team that turns blank BTO flats into liveable homes on a tight budget is rarely the same one you want reworking a three-storey landed house or a luxury condo. So I spent a few weeks researching this properly, cross-referencing Qanvast and Google reviews, HDB renovation-contractor registration, CaseTrust accreditation, award history, pricing transparency and the kind of projects each firm actually does best.
What came out of it is this list of ten interior design companies, chosen to cover the full spread of Singapore homes: HDB BTO and resale flats, condos and apartments, and landed houses, with a couple of firms that also handle commercial and high-end work. Some are large, award-heavy outfits with hundreds of reviews. Others are smaller studios that do one thing exceptionally well. I have ranked them by overall strength, but read the notes more than the numbers, because the best interior designer for your home is the one that fits your property type, budget and taste.
I have kept this editorial and independent. No firm paid to be here. Below are the ten interior design firms in Singapore I would actually recommend to a friend, followed by how to choose between them, rough costs, and answers to the questions homeowners ask me most.
Key Takeaways
- 1 There is no single best interior design firm in Singapore, only the best one for your property type. A BTO package specialist and a landed-home firm are judged on completely different things.
- 2 For a dependable all-rounder across HDB and condo, Swiss Interior and Starry Homestead are the two I would shortlist first. Both have long, consistent review histories.
- 3 Always check the firm is on the HDB Directory of Registered Renovation Contractors before any HDB work, and look for CaseTrust-RCMA accreditation for contract and deposit protection.
- 4 Renovation costs vary widely: roughly S$35,000 to S$60,000 for a 4-room BTO, and S$150,000 upward for a landed home, depending on scope and materials.
- 5 This is the hub for my property-specific guides. Once you know whether you are doing a BTO, resale flat, condo or landed home, dig into the dedicated guide for that property type.
How to choose an interior design firm in Singapore
Before the list, the checks that save the most money and heartache. The first thing I verify is registration. For any HDB flat, the firm doing your renovation should be on the HDB Directory of Registered Renovation Contractors, because only registered contractors are allowed to carry out renovation works in HDB flats, and using one keeps you on the right side of the rules for hacking, wet works and electrical changes.
The second is accreditation. The CaseTrust-RCMA joint accreditation scheme is the one I look for, because accredited firms must use a standard renovation contract, carry deposit protection, and follow a clear dispute process. It is not a guarantee of taste, but it is a strong signal that a firm handles your money and your timeline responsibly. For landed homes and bigger structural changes, check that the firm works with a BCA-licensed builder and, where addition and alteration works are involved, a qualified person such as an architect or a professional engineer.
After the paperwork, I weigh three things. Portfolio fit: do their past projects look like the home you want, in the same property type, since a firm with a wall of stunning condo interiors may have thin landed experience, and the reverse is just as true. Transparent, itemised quotes: the good firms break down carpentry, hacking, tiling and the rest, so you can compare like for like and see where the money goes. And reviews with substance: I weight Qanvast and Google reviews that describe the process, timeline and after-sales service far more than a raw star average. Because so much comes down to property type, I have dedicated guides for HDB BTO, resale HDB, condo, landed, commercial and luxury interior design, so once you know your property type you can go straight to the right shortlist.
1. Swiss Interior
Swiss Interior is the firm I would point most homeowners to first, because it does the fundamentals well across almost every property type. Since 2012 the team has completed work on hundreds of homes, from compact BTO flats to condos and landed houses, and the reviews keep circling back to the same two things: designs that are actually liveable, and a project that runs to schedule without nasty surprises.
What makes it a safe first call is the mix of range and reliability. They are an HDB-registered contractor with Blum-certified carpentry and a long run of Qanvast SuperTrust awards, which you only keep by holding consistently strong reviews year after year. If you want a dependable all-rounder that can handle your flat or condo without drama, start here.

Location: 126 Bukit Merah Lane 1, #01-214
Reviews: 4.78 on Qanvast (241 reviews), Qanvast SuperTrust 2021 to 2024
Best known for: Dependable all-round HDB and condo renovation since 2012
2. Urban Home Design
Urban Home Design is where I would send anyone who wants a calm, minimalist home and cares about design pedigree. Their work leans Scandinavian, Japandi and Wabi-sabi, all clean lines, warm neutrals and a few well-chosen materials, and it is genuinely award-winning: an iF Design Award in 2025 and a Singapore Good Design (SG Mark) in 2024 sit alongside a near-perfect Qanvast score.
Beyond the aesthetics, they are one of the more transparent firms on pricing, with itemised quotes that make it easy to see what you are paying for. They handle HDB flats, condos and landed homes, but the minimalist, material-led style is the real reason to choose them. If your reference images are all soft, quiet and Japandi, this is the studio that will get it right.

Location: 100E Pasir Panjang Road, #01-02
Reviews: 4.99 on Qanvast (360+ reviews), iF Design Award 2025
Best known for: Award-winning minimalist, Japandi and Wabi-sabi interiors
3. Starry Homestead
Starry Homestead is one of the most decorated firms on this list, and it earns the reputation. Over more than a decade it has picked up nine consecutive Qanvast SuperTrust awards, which means close to ten years of sustained five-star client feedback, along with recognition from Nippon Paint. The portfolio spans HDB, condo and landed, with a clear strength in warm, textured styles like Japandi, Scandinavian and modern-oriental.
What reassures me here is the accreditation stack: HDB-licensed, BCA registered and CaseTrust-RCMA accredited, so the money and contract side is properly covered. They also run in-house custom carpentry, which tends to mean tighter quality control on the built-ins that make or break a renovation. For homeowners who want award-level polish with the paperwork done right, Starry is a strong pick.

Location: 18 Boon Lay Way, #01-101 Tradehub 21 (plus Balestier and Paya Lebar showrooms)
Reviews: 4.79 on Qanvast (430+ reviews), nine-time Qanvast SuperTrust
Best known for: Award-level residential design with full CaseTrust-RCMA accreditation
4. The Alchemists Design
The Alchemists Design is the firm I would shortlist for a bespoke, more design-led renovation. They position themselves around tailor-made interiors rather than fixed packages, and the portfolio backs it up across HDB, condo, landed and commercial spaces. The reviews are strong and plentiful, and the recurring theme is a team that listens closely and then executes with precision.
Two things stand out to me. First, they are upfront about pricing, which is rare enough in this industry to be worth flagging. Second, the finishing quality in their completed projects is consistently high, the kind of detailing that reads as expensive even when the brief was not. If you have a clear vision and want a firm that will refine it rather than flatten it, they are a natural fit.
Website: thealchemistsdesign.com
Location: 2 Gambas Crescent, Nordcom II
Reviews: Consistently rated above 4.8 across Qanvast and Google
Best known for: Bespoke, design-led renovation with transparent pricing
5. Design 4 Space
Design 4 Space is a proper veteran, more than a decade in with three showrooms across Toa Payoh, Paya Lebar and Boon Lay, which makes them easy to visit before you commit. They cover the full range from HDB to landed and commercial, and the volume of reviews they have gathered tells you they turn over a lot of projects without the reputation slipping.
For me the draw is the accreditation and track record: HDB-registered, CaseTrust-RCMA accredited and bizSAFE certified, with a house style that leans modern and quietly luxurious. If you want a large, established firm with the systems to handle a bigger or more complex renovation, Design 4 Space is a safe, experienced choice.
Website: design4space.com.sg
Location: Toa Payoh, Paya Lebar and Boon Lay showrooms
Reviews: 4.75 on Qanvast (390+ reviews)
Best known for: Established full-service firm with CaseTrust-RCMA accreditation
6. MET Interior
MET Interior has quietly built a strong name across HDB resale, BTO, condo and landed work since 2014. What stands out in their portfolio is versatility: they move comfortably between a budget-conscious resale flat makeover and a full landed renovation, and they handle commercial fit-outs too, which not every residential firm can.
The reviews point to responsive project management and designs that respect both the brief and the budget, which is exactly what most homeowners actually want. They are an HDB-registered contractor, so the HDB side is handled correctly. If your project is a resale flat that needs reconfiguring, or a landed home that needs a firm comfortable across floors and outdoor space, MET is well worth a conversation.

7. Space Atelier
Space Atelier is the one I would flag if your project has a commercial or mixed-use angle, because alongside a solid residential portfolio they do genuinely strong office and retail work. Founded in 2014, they take a tailor-made approach and have been recognised for customer service, which in this industry usually correlates with fewer headaches during the build.
On the residential side they cover HDB, condo and landed with a clean, contemporary style. Where they separate from the pack is that dual residential-and-commercial capability, so if you are a homeowner who also needs a shop, clinic or office fitted out by a team you already trust, you can keep it under one roof. Practical and steady.
Website: spaceatelier.com.sg
Location: 6 Harper Road, #05-07 Leong Huat Building
Reviews: 4.69 on Qanvast (390+ reviews)
Best known for: Residential plus genuinely strong commercial and office design
8. EightyTwo
EightyTwo plays in a different part of the market: high-end, understated luxury for condos, landed homes and developer projects. Founded in 2012, the studio has built a reputation on restraint, expensive-looking interiors that never shout, backed by a wall of design awards and a regional presence beyond Singapore.
This is not the firm for a quick, budget BTO package, and it does not pretend to be. It is the one to call when the budget is serious and you want a considered, architect-adjacent approach to a larger home. If your reference points are boutique hotels and quiet, tactile luxury rather than trend-driven feature walls, EightyTwo belongs on your shortlist.
Website: eightytwo.asia
Location: 600 North Bridge Road, #15-06 Parkview Square
Reviews: Boutique and award-led rather than review-volume driven
Best known for: Understated high-end luxury for condos and landed homes
9. The Local INN.terior
The Local INN.terior is a homegrown studio that leans into personality. Their whole pitch is designing spaces that reflect how you actually live rather than copying a showroom, and the portfolio ranges from modern minimalist to contemporary luxury and industrial across HDB, condo, landed and commercial projects.
With a large, consistent body of reviews and two showrooms including one on Rangoon Road, they are easy to shortlist. I would put them in front of anyone who wants a slightly more characterful, less templated result and enjoys the collaborative side of the process. They are HDB-registered, so the flat renovation basics are covered.
Website: thelocalinnterior.com.sg
Location: 158 Rangoon Road (plus Serangoon Garden showroom)
Reviews: 4.74 on Qanvast (410+ reviews)
Best known for: Character-led, collaborative design across home types
10. Homescape
Homescape rounds out the list as a design-and-build firm that keeps its trades in-house, masonry, carpentry, electrical and tiling under one roof, which can mean tighter coordination and fewer finger-pointing moments when something needs fixing. They work across BTO, resale HDB, condo and landed, with a practical, liveable style.
As a newer company they do not have the decade-long review history of some others here, so I would lean on their on-site testimonials, ask to see recent completed projects in your property type, and confirm the contract terms in writing. But the in-house build model and the warranty on cabinetry hardware are genuine points in their favour if you value accountability during the works.
Website: homescape.com.sg
Location: 3 Ang Mo Kio Street 62, #01-19 Link@AMK
Reviews: Newer firm; design-and-build model with in-house trades
Best known for: In-house design-and-build across HDB, condo and landed

If you want the shortlist in one view, here is how the ten firms line up by what they do best and the signal I trust most for each.
| Firm | Best for | Signal I trust |
|---|---|---|
| Swiss Interior | Dependable all-round HDB and condo | Qanvast SuperTrust, HDB-registered |

How much does interior design cost in Singapore?
The honest answer is that it depends on your property type, the scope of work and your material choices, but here are the ballpark design-and-renovation ranges I would budget for in 2026. These cover design plus the renovation itself, not furniture and appliances.
| Property type | Typical design and renovation cost |
|---|---|
| 3-room HDB (BTO) | S$25,000 to S$45,000 |
| 4-room HDB (BTO) | S$35,000 to S$60,000 |
| 5-room or resale HDB | S$50,000 to S$90,000+ |
| Condominium unit | S$40,000 to S$150,000 |
| Landed house | S$150,000 to S$500,000+ |
| Commercial or office | S$70 to S$200+ per sq ft |
Resale flats often cost more to renovate than new BTOs, because older units usually need hacking, rewiring and re-plumbing before the nice part even begins. Landed homes sit in a different league entirely once addition and alteration works, structural changes or a rebuild are involved. Always get an itemised quote so you can see exactly what drives your number.
How I put this list together
I do not accept payment for a place on these lists, and no firm here sponsored its entry. I weight Qanvast and Google reviews that actually describe the process, timeline and after-sales service, cross-check HDB renovation-contractor registration and CaseTrust-RCMA accreditation, and favour firms whose portfolio matches real Singapore homes rather than glossy overseas renders. Ratings and details were accurate when I wrote this, but they move, so confirm the current picture with each firm before you sign anything. I update this list when my view changes.
What is the difference between an interior design firm and a renovation contractor?
An interior design firm handles the design, space planning and look of your home, then manages the trades to deliver it. A renovation contractor focuses on the building works themselves, hacking, tiling, plumbing, electrical and carpentry, often without a dedicated design service. Many firms in Singapore do both under one roof, which is why the labels blur. For any HDB flat, whoever does the physical works must be on the HDB register of renovation contractors, whether you call them a designer or a contractor.
How do I check if an interior design firm is HDB-registered?
Search the firm on the HDB Directory of Registered Renovation Contractors. Only firms on that list are permitted to carry out renovation works in HDB flats, and it takes two minutes to confirm before you pay a deposit. If a firm is not on it and your home is an HDB flat, treat that as a red flag, no matter how good the portfolio looks.
How long does a home renovation take in Singapore?
For a typical HDB BTO the design and renovation runs about 8 to 12 weeks once works start, on top of a few weeks for design and approvals. Resale flats usually take a little longer, 10 to 16 weeks, because of the extra hacking and rewiring older units need. Condos vary with MCST rules and permitted working hours, and landed homes with structural or addition-and-alteration works can run many months. Build the approval and lead time into your plans, not just the renovation itself.
Should I hire an interior designer for a landed property?
For a landed home, yes, and ideally one with real landed experience. Multiple storeys, larger volumes, outdoor spaces, internal staircases and any structural or addition-and-alteration works make landed projects far more complex than a flat. You want a firm that works with a BCA-licensed builder and, where the works require it, a qualified person such as an architect or professional engineer. A designer who mostly does HDB packages can be out of their depth here, so check the portfolio for genuine landed projects before you commit.
The bottom line
The best interior design firm in Singapore is not a single name, it is the one that fits your property and your brief. For a dependable HDB or condo renovation I would start with Swiss Interior or Starry Homestead. For minimalist, award-level design go to Urban Home Design. For bespoke work look at The Alchemists Design, for resale and landed versatility MET Interior, and for high-end luxury EightyTwo. Whichever way you lean, check the firm is HDB-registered, ideally CaseTrust-RCMA accredited, and get an itemised quote before you sign.
If you run an interior design firm yourself, a website that shows your portfolio as well as your work deserves does a lot of the quiet selling for you. That is what I do at Terris. Take a look at my web design services or get a free quote if you want your studio to stand out online.
