Design 4 Space is a large, established interior design firm founded in 2012, with a team of 59 and 608 recorded projects split almost evenly between new (327) and resale (281) homes. Its work centres on 4-Room HDB (184), condominium (175) and 5-Room HDB (119) properties, with some landed and commercial projects. Average listed prices are highest for resale condominiums and landed homes, and the firm covers a wide style range, from contemporary and modern to Scandinavian and minimalist. It may suit homeowners seeking a full-service renovation across several property types rather than a niche specialist.

Strengths
Broad property coverage The portfolio spans 2-Room, 4-Room, 5-Room and Executive HDB flats, condominiums, landed homes and commercial spaces. This breadth suggests experience across most common Singapore housing types.
Established track record and capacity With 608 recorded projects, a 59-person team and operations since 2012, the firm has a sizeable delivery capacity. The new and resale project split also indicates work on both fresh builds and renovations of existing homes.
Relevant accreditations The firm is HDB Registered, CaseTrust-RCMA, BCA Registered and bizSAFE 3. These credentials are directly relevant to HDB renovation and construction work in Singapore.
Things to take note
Showroom count needs confirmation The firm profile describes four showrooms, but the structured data lists two. Homeowners planning to visit in person should confirm current showroom locations directly with the firm.
Limited evidence of niche specialisation Contemporary and modern styles make up most of the sampled projects, with fewer examples of distinctly niche styles. Homeowners with a very specific design direction may want to review project portfolios closely.

This is an AI-generated summary based on 504 homeowner reviews.

Recent homeowner reviews most often praise prompt, consistent communication, hands-on coordination of contractors, and quick attention to defects after handover. Some reviewers note that they had to bring their own design ideas forward, and that pricing sits above some alternatives, so the experience is judged largely on service rather than cost. Reviews also suggest the experience can vary between individual designers.

  • Regular progress updates reduce the need to chase
  • Hands-on coordination of contractors and timelines
  • Constructive suggestions and budget-aware alternatives

Things to take note

  • Not positioned as the lowest-cost option
  • Experience can vary by assigned designer

Best for homeowners who are

  • First-time renovators who value regular guidance and reassurance
  • Busy homeowners or those living overseas who want proactive project coordination

“Good service from Design 4 Space ID Max Yu”

When we were looking for a company that uses low formaldehyde wood, D4S came up as one of the companies. We were impressed by Max's sincerity. Usually on first enquiry, some ID firms will just discuss your requirements over the phone before giving you a rough quote. Max came to our place, took measurements and discuss our plans with us. Throughout our renovation journey, he is very responsible and responsive even after we have paid in full when work is done. Highly recommend D4S and Max Yu.

“Highly recommended Interior Designer”

After hearing many positive reviews about Vincent Chuah from Design 4 Space, we decided to engage him as our interior designer, and it turned out to be one of the best decisions we made for our home renovation journey. From the very beginning, Vincent demonstrated exceptional professionalism, knowledge, creativity, responsiveness, patience, attention to detail, and reliability. Just a few weeks before the renovation was due to commence, we had to make significant changes to the designs of our kitchen and three bedrooms due to feng shui considerations. Vincent was incredibly accommodating and proactive in understanding our needs. He made the necessary changes without hesitation and promptly provided alternative design ideas and practical solutions that met our requirements. Throughout the entire renovation journey, Vincent was always responsive and approachable. He managed the renovation process exceptionally well, ensuring that every stage stayed on schedule. No matter how busy he was, he consistently kept us updated on the progress, giving us tremendous reassurance and peace of mind. Whenever we encountered issues or unexpected challenges, Vincent was quick to respond and address them promptly. He took ownership of the problems instead of shifting responsibility and always did his utmost to find the best possible solutions. We never felt that we had to face any challenges alone, and his dedication and sense of responsibility gave us great confidence throughout the entire process. The renovation was completed in a timely manner, and Vincent's excellent service did not end there. His after-sales support was equally commendable, as he promptly and professionally arranged for contractors to resolve any post-renovation issues. The workmanship and overall quality were excellent as well. We feel truly blessed and grateful to Vincent for his hard work, commitment, and unwavering support throughout our renovation journey. His professionalism, reliability, creativity, and genuine dedication made what could have been a stressful experience a much smoother and more reassuring one. We would wholeheartedly recommend Vincent Chuah from Design 4 Space to anyone looking for a reliable, responsible, creative, knowledgeable, and talented interior designer. Thank you, Vincent, for making our home renovation journey such a positive and memorable experience! As Vincent is a highly sought-after interior designer, his schedule is often fully booked. We recommend making your appointment several months in advance to avoid disappointment.

“Excellent ID”

Lee Sing from Design4Space was the very first interior designer my wife and I met for our BTO renovation. From our first meeting, we felt she was the right person for us, and we decided to engage her right away. Throughout the entire process, Lee Sing managed our expectations well and helped us stay within our renovation budget. As first-time homeowners, my wife and I had many ideas and requests, some of which exceeded our budget. Instead of simply saying no, Lee Sing patiently suggested practical alternatives and creative solutions that allowed us to achieve a similar look without overspending. When we shared our preferred style and overall vision for our home, she also offered thoughtful design suggestions that enhanced the final outcome beyond what we had originally imagined. She was incredibly patient in answering all our questions, and whenever we had doubts or last-minute changes, she listened carefully and accommodated our requests whenever possible. Communication with Lee Sing was excellent throughout the renovation. She was always responsive, easy to reach, and kept us updated at every stage. We had great rapport with her, which made the entire experience smooth and enjoyable. With Lee Sing as our interior designer, the renovation process was virtually stress-free. Everything progressed according to schedule, with no major setbacks or hiccups. The 3D renderings she provided were impressive, and we were delighted that the completed home looked almost exactly like the designs. It was amazing to see our vision come to life. Overall, we are extremely satisfied with Lee Sing and the service she provided. We would definitely engage her again for any future renovation projects and would highly recommend her to anyone looking for a reliable, professional, and talented interior designer.

“Transforming HDB BTO to modern Home”

If you need an interior designer who is creative, efficient, and a total joy to work with, look no further than Emerson Chew from Design 4 Space (Toa Payoh). Actions speak louder than words, and I have absolutely no regrets about choosing Design 4 Space—the results speak for themselves. We started with a completely empty shell with no flooring, and I was entirely unsure of what I wanted. Emerson was there every step of the way to help me narrow down my choices, suggesting great ideas while clearly explaining the pros and cons of each. Emerson completely transformed our HDB BTO into a stunning, modern home that suits my entire family perfectly. Thank you, Emerson! Thumbs up for all your hard work!

“Three Renovations, One Trusted Designer — Lee Sing”

This is our third time engaging Lee Sing from Design 4 Space, so we now jokingly call her our “go-to interior designer”! Our first two projects were only small renovation works, but Lee Sing was still very patient and took the time to understand what we needed. She gave us many practical suggestions and never treated the projects casually just because they were smaller in scale. Because of those positive experiences, she was naturally the first person we thought of when we decided to renovate our entire home. This time, she helped us plan the whole house, including the kitchen, living and dining areas, bedrooms, furniture selection, colours and materials. We really like how the overall design feels consistent and well coordinated, while each space still serves its own purpose. The final result is very close to what we had hoped for. What we appreciate most is that Lee Sing truly listens. She does not only focus on making the home look beautiful, but also considers practicality, storage, comfort and our family’s daily lifestyle. She even took my daughter’s interests into account. My daughter enjoys making small models and has many favourite plush toys, books and meaningful gifts from her friends. Lee Sing thoughtfully designed a special little space where she can display her models, arrange her favourite toys, keep her books and treasure the gifts that are important to her. It may only be a small corner of the house, but to my daughter, it feels like her own little world. This was such a thoughtful and personal touch, and it made the design feel even more meaningful to our family. Lee Sing is also very considerate about our budget. She does not suddenly add unnecessary items halfway through the renovation or keep recommending the most expensive options. Whenever something may exceed our budget, she discusses it with us first and suggests suitable alternatives. She really tries to balance design, quality and cost, so that we can spend on the areas that truly matter. After working with her three times, we find Lee Sing patient, thoughtful, practical and reliable. Renovation can be stressful, but having a designer who understands your needs, your family and your budget makes the whole process much easier. There is definitely a reason why we keep going back to her. We would gladly recommend Lee Sing from Design 4 Space to anyone looking for a trustworthy and caring interior designer.

“Three Projects, One Reliable Designer”

Our journey with Lee Sing has truly been one of trust and continuity. The first time we worked together was around 2017, when we did a small kitchen renovation (cabinets, floor tiles, etc.). Although it was a minor project, her professionalism and sincerity left a deep impression on us. Communication was smooth, and she always listened patiently to our needs while offering practical suggestions. That experience made us feel she was not just a designer, but also a trustworthy friend. The second collaboration was in 2019, when we moved into our current home. Because of the positive experience before, we did not hesitate to ask her again for some simple modifications. She maintained the same dedication and attention to detail. Even though it was only a partial adjustment, the results made our living space more comfortable and once again proved her reliability and expertise. The third collaboration, which is this time and also the largest, was a full house renovation. Transforming our old home into a completely refreshed space was truly meaningful for us. The original layout was neat but rather plain and utilitarian, lacking warmth and modern style. After Lee Sing’s design and renovation, our home became modern, minimalist, and cozy. Storage is more efficient, lighting and atmosphere have greatly improved, the bedroom feels calm and restful, the bathroom is fresh and elegant, the kitchen and dining area flow better, and the living room has become our favorite gathering place. Every corner reflects her thoughtfulness and professionalism. What we especially appreciate is that she is not only highly skilled in design but also honest and transparent throughout the process. She never exaggerates or misleads, and her communication always gave us peace of mind. After three collaborations, our trust in her has only grown stronger, and we feel this relationship has gone beyond just client and designer. Now, whenever we walk into our home, we often feel that this is no longer just a living space—it is truly our “home.” All of this would not have been possible without her effort and dedication. We are deeply grateful to Lee Sing and sincerely recommend her to anyone looking for a reliable and trustworthy designer.

“Renovation work”

I’m very happy with designer Vincent Chuah, who fulfilled our request and helped us move in two weeks earlier than the expected date. The whole process was generally smooth and hassle-free, and his creative ideas made our space look modern, stylish, and comfortable. The final result truly exceeded our expectations. Our home now feels fresh, functional, and welcoming, and we really enjoy spending time in the new space every day. Vincent was professional, efficient, and able to bring our vision to life within a short timeline. I would definitely recommend Vincent Chuah to anyone looking for an interior designer who is creative, reliable, and able to deliver beautiful results quickly and professionally.

“Review for Design 4 Space – Elynn & Wayne”

We found Design 4 Space through Qanvast and worked with Elynn, with Wayne supporting us throughout the journey. Elynn was our main point of contact and managed the contractors directly, while Wayne provided steady support behind the scenes, making the whole process feel well rounded and reliable. A strong deciding factor for us was the assurance of Design 4 Space’s CaseTrust accreditation and the Qanvast Guarantee, which gave us complete peace of mind. On top of that, Design 4 Space is the local distributor for Ecoply Wood and Ecoply Contact Adhesive – both certified as among the lowest formaldehyde emission plywood and glue in the market – making them likely the most cost efficient choice for homeowners who prefer low-formaldehyde products. Beyond these advantages, Elynn herself was straightforward in our communications, respected our budget clearly, and was upfront about additional charges before decisions were made. There were no surprises about hidden costs in our renovation journey. Over the few months we worked together, Elynn always answered our many questions patiently and guided us through each phase of the renovation. Communication was smooth and consistent – we never felt ghosted – and she even handled a neighbour’s complaints about renovation noise during the day without troubling us, only updating us afterwards. Elynn’s ability to refine our ideas and translate them into specifications for her contractors was the most valuable asset to us. We had a general sense of what we wanted, and she helped sharpen those concepts – advising us on which premium features were worth investing in and which ones weren’t necessary. Her guidance made our vision come to life in a practical, cost effective way. During the renovation phase, Elynn’s coordination with contractors was excellent. She held them accountable as much as was within her control, ensuring everything stayed on track and the house was even delivered ahead of schedule. This was when we especially felt solidified in our decision to work with an interior designer. Elynn managed all aspects so well that we didn’t feel the need to visit the house at all until completion, because we trusted her capabilities that much. At handover, the house was in great condition, and the minor issues we jointly spotted (renovation will never be perfect!) were resolved within the week thanks to her firm management of her contractors. Elynn also emphasized the one year post renovation warranty and reassured us that we should not hesitate to reach out if any need arises. Together, Elynn and Wayne were transparent, honest, and especially reassuring for us as first time homeowners. They provided great customer service, strong communication, and made the renovation journey far less stressful than we expected. If you have ideas for your home and want someone who can refine them while advising where to spend for maximum impact and where to save to stay cost efficient, Elynn – with Wayne’s consistent support – is truly a secret weapon you’ll want by your side. We cannot recommend them enough and are confident that you’ll have as pleasant an experience as we had with them!

“Beyond Our Expectations – Daniel from Design 4 Space”

We had a wonderful experience working with Daniel from Design 4 Space for our home renovation. Daniel is extremely talented and was able to understand our requirements almost immediately. He consistently provided multiple creative and practical suggestions on the spot, many of which were ideas we would never have thought of ourselves. Throughout the entire renovation journey, Daniel guided us patiently and professionally. He not only advised us on the renovation works, but also took the time to guide us on what to look out for when selecting furniture and lighting, which was incredibly helpful for us. What we appreciated most was that he always provided options that were either value for money or more cost-effective alternatives to help us manage our budget without compromising on quality or aesthetics. The project was also completed ahead of schedule, which exceeded our expectations. Even after completion, Daniel was very responsive in following up on any defects and ensured that issues were rectified promptly without delay. As both of us are busy with work, we usually only text him at night. Despite this, his replies to our queries were almost always immediate, which we truly did not expect. This responsiveness was especially important whenever we needed urgent advice before purchasing furniture or lighting. Most importantly, our home turned out beautifully designed, functional, and cosy — exactly what we hoped for and more. We are extremely happy with the outcome and would highly recommend Daniel to anyone looking for a reliable, talented, and dedicated interior designer.
