How Much Do Architects Cost in Singapore? (2026 Guide)

Hiring an architect in Singapore covers a wide scope of professional services: schematic design, construction drawings, regulatory submissions to the Urban Redevelopment Authority (URA) and Building and Construction Authority (BCA), project management during construction, and coordination with engineers and contractors. Some firms also handle Singapore Civil Defence Force (SCDF) submissions for works that require fire safety clearance. Whether you are building a new landed house, extending an existing property, or undertaking a significant interior reconfiguration that requires planning permission, an architect is both a legal requirement and a practical necessity in many scenarios.

Costs vary considerably because no two projects share the same brief, site constraints, or regulatory complexity. A straightforward single-storey extension on a standard terrace house carries a very different fee from a full rebuild of a Good Class Bungalow with bespoke structural requirements. The architect’s experience, firm size, fee structure (percentage-based or lump sum), and the construction budget all feed directly into what you will pay. Understanding these variables before you contact firms puts you in a much stronger position to evaluate quotes accurately.

What Do Architects Cost in Singapore?

As a general guide, architect fees in Singapore typically fall between 5% and 12% of the total construction cost, though the exact percentage depends heavily on project scope and the firm’s reputation. For a landed house rebuild with a construction cost of SGD 600,000, you would typically expect architect fees in the range of SGD 36,000 to SGD 72,000. Smaller projects — such as a single-storey extension costing around SGD 150,000 to build — might attract fees of SGD 12,000 to SGD 22,000, sometimes quoted as a lump sum rather than a percentage. Complex or architecturally distinctive projects, particularly larger landed properties or multi-unit developments, can see fees exceed SGD 200,000.

Some firms charge a fixed lump sum fee agreed upfront, which gives homeowners greater cost certainty. Others use a percentage-fee model tied to the final construction cost, which means costs can shift if the build scope changes. Always clarify which model applies before signing an agreement. BCA and URA submission fees are usually charged separately and are not always included in the architect’s quoted fee, so ask for a full fee breakdown that accounts for all disbursements and consultant coordination costs.

What Affects the Cost of Architects in Singapore?

Project complexity and size

A small single-storey extension requires far less design work and fewer regulatory submissions than a complete rebuild of a detached landed house. More complex structures — those with unusual site shapes, changes of use, or proximity to conservation zones — demand additional design time, specialist reports, and more thorough URA and BCA submissions. Complexity is the single biggest cost driver.

Construction cost and fee structure

Where fees are calculated as a percentage of construction cost, a higher-spec build with premium finishes automatically produces a higher architect fee even if the floor area is identical to a simpler project. A house built to a construction cost of SGD 400 per square foot will generate a higher percentage fee in absolute dollar terms than one built at SGD 250 per square foot. Always think of the architect fee alongside the projected construction budget, not in isolation.

Architect’s experience and firm reputation

Established firms with a strong portfolio of landed houses in Singapore, or those who have won awards for residential design, command higher fees than smaller practices or recently registered architects. This is not simply a prestige premium — experienced architects often save clients money by anticipating problems before construction begins, managing contractors more effectively, and producing drawings that require fewer costly revisions on site. A firm’s reputation in handling BCA and SCDF submissions efficiently also has real value, particularly on projects where delays cost money.

Regulatory submissions required

Projects that require submissions to URA for planning permission, BCA for building plan approval, and SCDF for fire safety add professional time and disbursement costs. Some straightforward additions may qualify for a simpler Structural Plan submission only, whereas a full rebuild triggers the complete submission cycle across multiple authorities. Each submission adds to the architect’s workload and, consequently, the fee.

Scope of project management

Architects who provide full site supervision and contractor management throughout the construction phase charge more than those who hand over once the drawings are approved. For most homeowners, paying for regular site supervision is worthwhile — it reduces the risk of unapproved deviations from the drawings, protects against contractor disputes, and ensures the finished structure matches what was designed and approved.

How to Get Accurate Quotes

1. Prepare a clear project brief before contacting any firms. Include your site address, approximate floor area, intended scope of works, rough budget, and any known constraints such as conservation status or plot ratio limits.
2. Request quotes from at least three firms with demonstrated experience in projects similar to yours — particularly if your project involves landed houses, as Singapore’s landed residential regulations are specific and experience matters.
3. Ask each firm to provide a written fee proposal that separates design fees, submission fees, disbursements, and any additional consultant coordination costs. A quote that bundles everything together makes comparison difficult.
4. Clarify whether the fee is a lump sum or percentage-based, what triggers variation in the fee, and what is excluded from the scope. Ask specifically whether BCA, URA, and SCDF submissions are included.
5. Check that the architect is registered with the Board of Architects Singapore. Registration is a legal requirement to practise as an architect in Singapore, and you can verify this directly on the Board’s public register before committing to any agreement.

Red Flags to Watch Out For

• A firm that provides a fixed quote before visiting the site or reviewing any drawings. Accurate fees require a proper assessment of the project scope and regulatory requirements.
• No written fee agreement. Any reputable architect will provide a formal letter of appointment that sets out the scope, fee, payment schedule, and terms before work begins.
• Fees that seem significantly below market rate without a clear explanation. A very low fee often means limited site supervision, drawings produced by unqualified staff, or exclusions that will be charged as extras later.
• Vague responses when asked about URA and BCA submissions. Architects who cannot clearly explain the submission process for your project type may lack the experience to handle it correctly.
• No portfolio of completed landed house projects in Singapore. Residential architecture here has specific local regulatory and climatic considerations — an architect whose experience is primarily in commercial or overseas projects may not be the right fit.
• Pressure to sign quickly without time to compare quotes or review the agreement. Reputable firms understand that homeowners need time to make an informed decision on what is typically a significant financial commitment.

Frequently Asked Questions

How much do architects cost in Singapore on average?

For a typical landed house project in Singapore, architect fees generally range from SGD 25,000 to SGD 80,000, depending on project size and complexity. This usually represents 6% to 10% of the total construction cost. Smaller projects such as minor extensions may fall below SGD 20,000, while large or architecturally complex builds can exceed SGD 150,000 in professional fees alone.

Why are some architects’ prices so much cheaper?

Lower fees often reflect a reduced scope of service. A firm charging significantly less may exclude site supervision, provide fewer design iterations, outsource drawings to junior staff, or charge submission fees and consultant coordination separately. In some cases, the lower fee reflects genuine efficiency in a firm that specialises in a narrow project type. Always compare quotes on a like-for-like basis by checking exactly what is and is not included before assuming a cheaper quote represents better value.

Is it worth paying more for architects in Singapore?

For most homeowners, paying for an experienced architect with a strong track record in Singapore landed house projects is a sound investment. Good design can add to the long-term value of a property, and effective project management reduces costly errors and contractor disputes during construction. Given that construction costs for a landed house rebuild in Singapore commonly exceed SGD 500,000, the architect’s fee is a relatively small proportion of the total outlay — and the cost of poor design or inadequate supervision can far exceed any saving made on professional fees.

Getting the right architect for your project in Singapore comes down to matching their experience to your specific needs, understanding exactly what the fee covers, and taking the time to compare at least three written proposals. Price is one factor, but the quality of the drawings, the firm’s familiarity with URA, BCA, and SCDF requirements, and their track record in managing contractors on site will have a far greater bearing on whether your project finishes on time, on budget, and to the standard you expect.
