Seiji Interior is a small, newer interior design firm, established in 2024, with a team of six and one showroom. Its 13 listed projects are concentrated in HDB flats, especially 5-room units (nine projects), with a few 4-room, 3-room and one condominium project. Listed project budgets range from about S$30,000 to S$120,000, which suggests a moderately priced positioning. The firm's profile cites Wabi-Sabi and Scandinavian as signature styles, though its projects span six styles. It may suit HDB owners seeking a mid-range renovation from a firm with a short track record.

Strengths
Verified accreditation The firm holds CaseTrust accreditation, a concrete credential that homeowners can check when comparing firms.
Consistent HDB experience Eleven of the 13 listed projects are HDB flats, including nine 5-room units, which indicates a focused and repeatable track record in the public housing segment.
Varied style range Listed projects span Minimalist, Scandinavian, Modern, Asian, Contemporary and Vintage styles, with Minimalist the most common at four projects, giving homeowners with differing tastes a range of past work to review.
Things to take note
Short track record Established in 2024, with 13 projects and no awards listed, the firm has a limited operating history for homeowners who prefer longer-established track records.
Stated signature style not visible in projects Wabi-Sabi is described as a signature style, but none of the listed projects is tagged with it, so homeowners wanting this aesthetic should ask for specific examples.
Limited non-HDB coverage Only one condominium and no landed or private-estate projects appear in the data, so the firm's experience with these property types is less evident.

New!

This is an AI-generated summary based on 84 homeowner reviews.

Homeowners consistently describe responsive communication, regular updates and hands-on project coordination, with several saying they rarely had to chase for progress. Designers are often credited with listening to lifestyle needs and offering practical advice rather than pushing upgrades. Reviews also point to small post-handover defects that were usually rectified, and some mention occasional miscommunication along the way.

What homeowners value most

  • Responsive communication with regular updates, so homeowners rarely need to chase
  • Designers ask about daily living and suggest practical solutions, not just styling
  • Transparent quotes with no hidden costs or unnecessary add-ons
  • Defects are handled after handover, including touch-ups months later

Things to take note

  • Minor defects after handover are common and need follow-up rounds
  • Occasional miscommunication during the works, usually resolved quickly

Best for homeowners who are

  • Busy homeowners who prefer proactive coordination and minimal involvement once works start
  • First-time renovators who value regular guidance, explanations and reassurance
  • Homeowners who want clear quotations and a designer who does not push upgrades

“100% hands-off once works started”

We had a great experience working with Celeste from Seiji Interior. She understood our aesthetics and preferences quickly, gave great recommendations on colours and finishes, and provided helpful mood boards and inspirations. She was patient, responsive and quick to revise drawings based on our feedback. Her attention to the little details and excellent project management made the renovation incredibly smooth — we were 100% hands-off once work started. Communication and coordination between Celeste, us and the contractors were seamless. She is open to touch-ups on small details on our flat even 7 months after handover. Highly recommended!

“BTO Bathroom Upgrade”

We engaged Stacia for our bathroom upgrade and had a really good experience. She was patient, responsive and helped us come up with a design that suited our style and budget. She gave practical suggestions and kept us updated throughout, making the whole process smooth and stress-free. The workmanship was neat and everything was completed on time. Really happy with how the bathroom turned out! Would recommend the services for friends and relatives

Design

The measurements were customised. Stacia asked us a few questions to understand our daily life, then suggested materials and designs that were practical and stunning

Workmanship

the installation was quite quick, they laid out protection sheets in our living room and bedroom to protect our tiles

Customer Service

Stacia is very responsive and quick in understanding our concerns, helped us find solutions. Shes very friendly as well

Value for Money

there were many things we did not know, and having an ID really helped with the process. Stacia was really transparent on the quote, and managed to fit all our criteria while staying in budget

“Excellent experience”

Thank you, Lincoln, for building our dream home from start to finish. Everything was thoughtfully planned and executed efficiently, and we barely encountered any issues throughout the entire renovation process. What impressed us most was not just the quality of his work, but also his exceptional service and after-sales support. Lincoln was always responsive—we never had to wait more than a day for updates or replies, even after full payment was made. That level of professionalism and commitment is hard to find. On top of that, his quotation was the most affordable among all the firms we considered, and unlike many others, he didn’t inflate prices with unnecessary add-ons. We truly appreciate his honesty, reliability, and dedication, and would highly recommend him to anyone looking for a trustworthy contractor.

“Superb and smooth working with Mavis”

We engaged Mavis for our renovation and it was one of the best decisions we made. From the initial consultation, she took the time to understand our lifestyle and preferences, and translated that into a design direction that truly felt like us: Warm, calm, and clutter-free. Mavis has a great ability to balance aesthetics with practicality. Every detail was thought through. The walnut open shelving unit paired with cream cabinetry in the living area, the open kitchen island with a glass partition that keeps the space feeling connected yet functional, a full wardrobe wall with a tucked-in dressing nook, and a bathroom that genuinely feels like a boutique hotel escape. Lighting was something we didn't expect to make such a big difference. Mavis incorporated under cabinet strips, recessed spotlights and LED accents throughout that completely transform the mood of each room in the evening. The renovation process itself was super smooth. She communicated clearly at every stage, managed timelines well, and was responsive whenever we had questions or concerns. We never felt left in the dark. If you're looking for an interior designer who brings both a strong creative vision and professional reliability to the table, we'd highly recommend Mavis without hesitation. Our home is everything we hoped for and more. Thank you Mavis!

“Dream Home Brought to Life — Exactly Like the 3D Render”

Couldn’t be happier with our home renovation journey with Mavis!! From the very beginning, she really understood the vision we had for our dream home and brought it to life so beautifully. What impressed us most was how the final outcome turned out almost exactly like the 3D renders — every detail, colour palette, and design element was executed so accurately. The whole space feels both aesthetic and functional, and you can really tell she puts a lot of thought into her work. Mavis was also patient, responsive, and easy to communicate with throughout the process, which made everything much less stressful. Thank you for creating a home we genuinely love coming back to every day!

“Minimalistic design in Tiong Bahru”

We first came across Celeste & Lennon through their company (Seiji Interior) TikTok, and their work immediately stood out. In fact, when we were speaking to other interior designers, we kept referring back to their projects as the benchmark for the style we wanted. Eventually, we thought—why not just go straight to the source? That turned out to be one of the best decisions we made. From the very beginning, they understood our vision almost instinctively. What impressed us most was how seamlessly our ideas aligned with theirs—they didn’t just follow our brief, they elevated it with thoughtful details and creative touches that made the design feel truly ours. Equally important was their ability to balance aesthetics with practicality. Budget was a key consideration for us, and we were pleasantly surprised that working directly with them did not significantly increase costs. Throughout the process, they were transparent, mindful, and strategic, ensuring we achieved the look we wanted without unnecessary overspending. Their speed of execution was also remarkable. Timelines were managed efficiently, communication was clear and responsive, and everything moved forward with a sense of momentum that made the entire experience smooth and stress-free. Working with Celeste & Lennon felt less like engaging a vendor and more like collaborating with a team that genuinely cared about bringing our home to life. We couldn’t be happier with the outcome and would highly recommend them to anyone looking for a refined, well-executed, and thoughtfully managed design experience. Highly recommend both of them for a minimalistic themed house!

We came across Celeste from Seiji Interior through her Instagram page. After seeing her portfolio, we arranged a meetup for a discussion, and from the very first meeting we felt comfortable and confident in her, so we decided to engage her for our home renovation. As first-time homeowners going through renovation, there were naturally many things we were unfamiliar with. We’re really thankful that we found Celeste, as she was always there whenever we needed advice or assistance. She was responsive, patient, and reassuring throughout the process, which made the journey much easier for us. Like most renovation journeys, there were naturally some hiccups along the way, but Celeste was always willing to step in to help and guide us whenever needed. Her support and reassurance throughout the renovation process meant a lot to us. Now that everything is completed, we’re very happy with how our home turned out ? We would definitely recommend Celeste to anyone looking for an interior designer who is supportive, reliable, and committed to helping you create a home you love ?❤️

“Good Project Managment and smooth process”

Very impressed with the quality of this bathroom build. The workmanship is excellent — clean tile alignment, neat finishes, and a very well-thought-out layout that maximises space without feeling cramped. The shower area, glass panel, and fittings are installed with great attention to detail, giving the whole toilet a modern and premium feel. Beyond the final outcome, the designer’s project management really stood out. He was highly responsive throughout, accommodating to requests and constraints, and resourceful in proposing practical solutions without compromising on aesthetics. Communication was clear and timely, which made the entire renovation process smooth and stress-free. Highly recommended for anyone looking for quality workmanship and a reliable, professional designer.
