9 Best Condo Interior Design Firms Singapore (October 2026)

Their design style leans toward modern classic and transitional, which is a sweet spot for condo owners who want elegance without the risk of a trendy look dating itself in three years. I have gone through dozens of their project photos, and the consistency is impressive. They do not appear to have an "off day" when it comes to design quality. Clean lines, thoughtful lighting, and restrained colour palettes run through almost every project.

With a 4.9 out of 5 rating across 500+ reviews and CaseTrust accreditation, Swiss Interior is one of the highest-rated firms in Singapore by sheer volume of positive feedback. If your taste runs toward timeless rather than trendy, they deserve a serious look.

Their condo track record is one of the deepest on this list: 73 completed condo projects with an average cost of S$162,167. That average gives you a realistic benchmark if you are budgeting for a full condo renovation in Singapore. It is not cheap, but for the scope and quality of work they deliver, it aligns with what I would expect from a top-tier firm.

On Hometrust, they hold a 9.2 out of 10 rating, ranking #9 out of 2,447 designers with 235 reviews. On Qanvast, they score 4.7 out of 5 with over 400 reviews and have earned the Supertrust badge every year from 2019 to 2025. They are also CaseTrust accredited. When a firm maintains that level of consistency across hundreds of reviews and multiple platforms over seven consecutive years, you can trust that the experience is reliable.

Founded in 2010 with over 20 years of combined industry experience, their design aesthetic centres on modern luxury. Their condo projects tend to feature bold material choices, statement lighting, and a polished finish that leans upscale. For condo owners who want their unit to feel like a show flat at a new launch, Space Factor delivers that level of finish.

Typical condo renovation costs with Space Factor range from S$40,000 to S$80,000 and above, depending on the scope. That flexible pricing model means you can start with the essentials and add on as your budget allows, rather than committing to a fixed package that might include things you do not actually need.

With over 10 years of operation, a Hometrust rating of 9.1 out of 10, a Qanvast score of 4.7, and CaseTrust-RCMA approval, they tick every credibility box. But what I find most interesting about their work is the emphasis on space-saving solutions and harmonious design. Their condo projects consistently show smart storage integration, multi-functional furniture layouts, and a calm aesthetic that makes compact spaces feel liveable rather than cramped.

For condo owners dealing with tight square footage (which is most condo owners in Singapore), a firm that specialises in making small spaces work harder is exactly what you need. Starry Homestead has turned that into their core competency.

Their design style skews toward modern luxury with a showroom-quality finish. Looking through their portfolio, their condo projects have a polished, editorial feel to them. Lots of clean surfaces, integrated lighting, and high-end materials. If you have seen a condo project on social media that made you think "that looks like a magazine shoot," there is a good chance it was a Space Atelier project.

Pricing is transparent, too. Their average cost for a new condo sits at S$51,852, while resale condos (which typically need more work) average S$97,894. Those benchmarks are helpful for budgeting and set realistic expectations before the first consultation.

Their credentials are equally impressive. They hold a 4.8 out of 5 on HomeMatch across 800+ reviews, 4.7 on Google, and have won the Singapore Prestige Brand Award, the Spirit of Enterprise Award, and the HDB Quality Partner designation in 2020. Perhaps most notably, they were appointed as the HDB show flat designer from 2017 to 2023. Being selected by HDB to design their show flats is a significant vote of confidence from a government body.

While Ciseern handles a wide range of residential projects, their sheer volume means they have seen virtually every condo layout in Singapore. Whether you are dealing with a shoebox unit, a dual-key condo, or a penthouse, chances are they have designed a similar space dozens of times before.

What sets Fineline apart is their versatility. Their portfolio spans minimalist, contemporary, industrial, and Scandinavian styles, all executed with a level of detail that shows genuine craftsmanship. I have noticed that some firms do one style brilliantly but stumble when a client asks for something outside their comfort zone. Fineline does not appear to have that problem. Their detail orientation shows up in the small things: precise carpentry joints, consistent material finishes, and thoughtful hardware selections.

With an average project cost of S$92,212, they sit at the higher end of the market. But for condo owners who are willing to invest in quality finishes and meticulous execution, Fineline delivers value that justifies the price point.

Founded in 2010, Absolook handles a broad range of project types including HDB, condos, landed properties, and commercial spaces. Their condo work shows a clean contemporary aesthetic with practical layouts and a focus on making the design process transparent for homeowners. I appreciate firms that demystify the renovation journey, and Absolook's process documentation suggests they prioritise keeping clients informed at every stage.

For condo owners who value an award-winning pedigree and a transparent design process, Absolook is well worth a consultation.
