Benjamin Lim
My partner and I had a wonderful experience working on our home renovations with the team at Pi Architects (Ivan and Jin Ling)! Ivan and Jin Ling have exceptional attention to detail and a keen eye for design, materiality, and proportions. Throughout the construction phase, they were responsive and proactive in managing the project and troubleshooting any issues that arose. We really appreciated that they were both genuinely excited about the project and took great pride in their work 🙂 We couldn’t have asked for a better team to bring our dream home to life! Thank you guys!!
Joyce H.
We got Ivan’s team to renovate our dated terrace house, and we’re happy with how it turned out. Big thanks to Zayar, Felyna, and Roong Er — the end result is a clean, minimal modern home that suits our lifestyle. Their ideas were mostly practical, thoughtful and they were a breeze to work with. There was an issue with a sharp step in the backyard, but the team responded quickly and fixed it without any fuss. Overall, we’re pleased with the outcome and grateful to the team for bringing our vision to life.

A great experience with Ivan and his team on a long project for our store. Great design, great communication, and good PM along the way. Though they didn’t have much experience with commercial projects when we first engaged them – their vision, excitement, and willingness to understand and address our needs is what made us go with them. It was an excellent choice. Thank you guys!

Christina
We had the pleasure of working with Adrian of RG Architects on the reconstruction of our 2.5-storey semi-detached house in Singapore. Right from the start, he impressed us with a design that beautifully balanced modern aesthetics with practicality. The exterior architectural features turned out to be so striking that even our neighbours approached us for the architect’s contact – a true testament to the quality and appeal of the work! Throughout the entire process, Adrian remained professional and detail-oriented, diligently overseeing the reconstruction and personally inspecting the contractor’s work to ensure it strictly followed the approved designs. Even after completion, he continued to provide full support during the Defects Liability Period (DLP), ensuring all rectification works were done promptly and to our satisfaction. That level of post-project commitment is deeply appreciated. It gave us peace of mind working with Adrian Goh and RG Architects who has delivered quality and client satisfaction
Michelle K
RG Architects managed the design of our new home which was completed in 2023. It was a long journey to plan and build a new home but with the support of RG Architects team, we now have a beautiful, comfortable and modern design home. The end result is fantastic and we are extremely happy. Adrian and team are awesome with great suggestions and dedication. Highly recommended.
YY Z
Adrian and team at RG Architects, many thanks for your work on my house. The size of the piece of land involved was quite tight, but through thoughtful design, the team was able to maximise the use of the space and plan for a house that perfectly met my requirements. The entire planning, design and construction process was also well managed, allowing me to keep to my budget and, despite the disruptions caused by Covid, minimise additional delays to the construction process. The end result is a house that is not only beautifully and tastefully designed, but also functional in nature. Thank you!

EJ
We have just recently moved into our dream house designed by AR43 and we absolutely love it. It was amazing how he managed to design such a stunning place with a small piece of land. The principal architect, Cheng Kooi is very meticulous and detailed, with high standards. His architectural design not only showcased creativity but also demonstrated a deep understanding of functionality vs aesthetics. His attention to detail and commitment to delivering high-quality work are truly commendable. Very importantly, he gave very good advice on the selection of the right contractors, suppliers and materials to be used. Thank you AR43!
Hui See Tan
I was in construction film and was fortunate to work with Mr. CK Lim and team for a temple project. Like many other have mentioned, not only he is detailed, creative, efficient but fair to builder. And guess what…. The project has won the prestigious International Architecture Awards! I am indeed honoured to have the chance to work with Sir Lim and team.
Chia Pix
This is a belated testimonial recognizing Mr Lim Cheng Kooi’s robustness as a gifted house-creator: in the late 90’s, still under the firm of Akitek Tenggara, he swiftly translated our brief to design a family home for 8 bursting out of a single-storey bungalow. Single-handedly, he fulfilled our laborious wants and needs with a design we could never have thought of on our own (and we had tried). The team that eventually won the tender was professionally overseen by Mr Lim who, at the same time, was setting up a new Company of his own. Glad to have met the right man at the right time, and happy to see that his visionary hand has gone on to shape so much of Singapore’s built environment!

BestLah’s Recommendation
Now that you’ve explored some of Singapore’s leading architecture firms, the next step is choosing the one that aligns most closely with how you plan, build, and live in your space. Each firm excels in different areas, so here are three focused recommendations based on real strengths and project fit.
1. If You Want Smart Space Planning On Tight Sites Without Compromising Design
Our Pick: AR43 Architects
AR43 Architects is a strong choice if you’re working with a tight plot, site constraints, or a fixed budget but still want a home that feels spacious and refined. Homeowners often highlight how the team maximises limited land through smart planning, turning challenging sites into well-balanced, liveable spaces. Reviews frequently mention the principal architect’s meticulous attention to detail and ability to balance aesthetics with everyday functionality.
AR43 also stands out for offering clear, practical guidance on materials, contractors, and construction decisions, helping clients manage costs without compromising design quality. This makes them well-suited for homeowners who value thoughtful layouts, realistic budgeting, and an architect who understands how design choices affect both build costs and long-term living comfort.
2. If You Want An Architect Who Truly Listens And Designs Around You
Our Pick: PI Architects
Choose PI Architects if you want to feel heard at every stage of the project. This is a firm for clients who already have ideas, opinions, or specific lifestyle needs and don’t want to be boxed into a preset design style. You’ll work closely with the same core team from concept to construction, which means fewer miscommunications and more control over the final outcome. This is especially valuable if you’re renovating a family home, a shophouse, or a business space where daily use, flow, and practicality matter just as much as visual impact. PI Architects suits you if you enjoy collaboration, value thoughtful problem-solving, and want a design that feels unmistakably yours.
3. If You Want Peace Of Mind For A Big Or High-Stakes Project
Our Pick: DP Architects
DP Architects is the right choice if your project is large, complex, or time-sensitive and you don’t want to gamble on execution. When you’re dealing with commercial spaces, mixed-use developments, or anything involving multiple authorities and consultants, experience and structure matter more than experimentation. DP’s size means there are dedicated teams handling planning, sustainability, technical coordination, and compliance, reducing the burden on you as the client. This firm suits you if you prioritise reliability, long-term performance, and proven delivery over hands-on creative involvement.
Final Thoughts
Singapore’s architectural landscape is a dynamic blend of creativity, precision, and cultural storytelling. From large-scale urban landmarks to intimate residential spaces, these six firms showcase the very best in design innovation and client-focused solutions. Whether you’re aiming to elevate your home, office, or commercial space, partnering with the right architecture firm can transform ideas into reality.
Once you’ve picked a firm that aligns with your vision, the next step is bringing those designs to life. Don’t forget to work with the best carpenters in Singapore to craft and execute your dream spaces down to the finest detail. With the right collaboration, your architectural vision can truly flourish.
Frequently Asked Questions (FAQ)
2. Do I need an architect for my HDB or Condo renovation?
For most HDB renovations, you generally do not need an architect. HDB has its own list of approved contractors who handle standard permits. However, if you are doing a massive configuration change that involves structural walls, HDB will require a Professional Engineer (PE) to certify the works.
For Condominiums, an architect is usually only necessary if you are making major external changes (like extending a balcony or changing the facade) which require URA approval. For internal "fit-outs," most owners engage an interior designer or a contractor directly.
3. How are architectural fees calculated in Singapore?
Fees are typically calculated as a percentage of the total construction cost. For a new house or a full reconstruction, fees generally range from 6% to 10%. For "Additions & Alterations" (A&A), the percentage is often higher—between 8% and 12%—because working within an existing structure is often more complex and time-consuming than building from scratch. Some firms may offer a fixed lump-sum fee for very specific, smaller scopes of work.
4. What is the "50% Rule" for Landed Properties?
When renovating a landed house, Singaporeans often ask whether their project is an Addition & Alteration (A&A) or a Reconstruction. This is a critical distinction because it affects your budget and the taxes you pay.
- A&A: Generally keeps costs lower. To qualify, you must not increase the Gross Floor Area (GFA) by more than 50%, and you must retain more than 50% of the existing external walls and structural elements.
- Reconstruction: If you exceed the 50% limit or add an extra storey, the project is classified as reconstruction. This requires you to comply with the latest building codes (e.g., providing a household shelter).
5. What is a "Qualified Person" (QP)?
In Singapore's legal context, a Qualified Person (QP) is a professional registered with the Board of Architects (BOA) or the Professional Engineers Board (PEB).
You need a QP to:
- Submit building plans to the BCA.
- Submit planning permissions to the URA.
- Obtain the Temporary Occupation Permit (TOP) and Statutory Completion Certificate (CSC) so you can legally move in.
6. How long does the entire process take?
For a typical landed property project (new build), the timeline is usually 18 to 24 months.
- Design & Planning (3–5 months): Finalising the layout and look.
- Authority Submissions (2–4 months): Waiting for URA and BCA approvals.
- Tendering & Contractor Selection (1–2 months): Getting quotes from builders.
- Construction (10–14 months): The actual building phase.
7. What are the "hidden" costs I should prepare for?
Homeowners often budget only for "Construction" and "Architect Fees," but there are several other costs:
- Surveyor Fees: To map out your land boundaries accurately ($1,500 – $3,000).
- Soil Investigation: To ensure the ground can support a new structure ($3,000 – $6,000).
- Other Consultants: You may need a Structural Engineer (C&S) and an M&E Engineer (for electrical/plumbing), whose fees are usually separate from the architect's.
- Maintenance Fund/Defects Liability: Setting aside 5–10% of the budget for unexpected issues during construction.
8. What is the "SIA Conditions of Contract"?
The Singapore Institute of Architects (SIA) provides a standard form of contract used between the homeowner and the builder. Singaporeans often ask about this because it protects the owner. It ensures that the architect acts as an independent "Contract Administrator," verifying that the work is actually done before you pay the contractor's monthly progress claims.
9. Can I maximise my "Gross Floor Area" (GFA)?
Every plot of land in Singapore has a "Plot Ratio" or "Envelope Control" guideline. Architects are frequently asked how to "squeeze" more space out of a plot.
- Attics: Can often be added without being counted as a full storey if they fit within the roof envelope.
- Basements: These can provide massive amounts of space, though they are significantly more expensive to build due to excavation and waterproofing costs.
- Voids: Double-volume ceilings are popular but usually count towards your GFA.
10. Does the architect help with selecting the builder?
Yes. A full-service architecture firm will manage the Tendering Process. They will:
- Prepare a "Bill of Quantities" or a detailed scope of work.
- Invite several contractors to bid.
- Analyse the bids to ensure they are "apples-to-apples."
- Recommend a builder based on track record and price, not just the lowest quote.
