Commercial interior design in Singapore is a significant investment, whether you are fitting out a corporate office, launching a retail concept, or developing a gallery with interactive experiences. Understanding cost structures, pricing benchmarks, and the factors that influence overall expenditure helps businesses plan realistically and avoid costly surprises.
This complete pricing guide explains what commercial interior design costs in Singapore typically look like, what drives those costs, and how to budget effectively — with special attention to Gallery Design, Interactive Gallery Design, interactive Solutions, and working with professional commercial interior designers.
How commercial interior design pricing works in Singapore
Commercial interior design costs are usually calculated using one or a combination of the following methods:
- Cost per square foot (psf)
This is the most common pricing structure for offices, retail, F&B, and gallery spaces. It usually covers construction, finishes, and basic installations. - Fixed project pricing
Some commercial interior designers provide fixed quotes based on an agreed scope, ideal for projects with clearly defined requirements. - Design fee (separate from build cost)
Interior design services may be charged as:- A percentage of total fit-out cost (commonly 8%–15%)
- A fixed design fee for concept, drawings, and project coordination
- Itemised pricing for specialist works
Interactive Solutions, AV systems, custom exhibits, and smart installations are often quoted separately due to their technical complexity.
Understanding which pricing model applies allows business owners to compare quotes accurately.
Average commercial interior design cost in Singapore
While prices vary by industry and finish level, the following ranges reflect common market benchmarks.
Office interior design costs
- Basic office fit-out:
SGD 70 – 90 per sqft
Suitable for functional layouts with standard finishes - Mid-range office design:
SGD 90 – 150 per sqft
Includes better materials, partitions, feature lighting, and branding - Premium office fit-out:
SGD 150 – 220+ per sqft
High-end finishes, custom carpentry, acoustic treatments, and advanced lighting
Retail interior design costs
- Small retail shops:
SGD 100 – 200 per sqft - Flagship retail & experiential spaces:
SGD 200 – 500+ per sqft
Higher costs are driven by custom displays, lighting design, and interactive Solutions.
F&B interior design costs
- Cafes and casual dining:
SGD 120 – 250 per sqft - Full-service restaurants:
SGD 250 – 600 per sqft
Kitchen equipment, exhaust systems, and compliance works significantly affect cost.
Gallery Design and Interactive Gallery Design
- Standard gallery fit-out:
SGD 120 – 250 per sqft
Typically white-box galleries with controlled lighting - Interactive gallery spaces:
20%–70% higher than standard galleries
Costs increase due to AV systems, projection mapping, sensors, custom exhibits, and software integration.
Interactive Gallery Design projects require closer coordination between designers, fabricators, and technology vendors.
Key factors that influence commercial interior design cost
Several variables can cause significant cost differences between projects:
- Space condition and structural changes
Major hacking, reinforcement, or layout changes add labour and approval costs. - Mechanical, electrical, and plumbing works (MEP)
Air-conditioning, power distribution, data points, and water supply are major budget components. - Material and finish selection
Imported materials, stone, metalwork, and custom laminates increase cost. - Custom carpentry and joinery
Bespoke counters, display systems, and feature walls are more expensive than modular options. - Lighting and acoustics
Essential for offices and galleries, especially where user experience and comfort matter. - Interactive Solutions and AV integration
Touchscreens, motion sensors, media walls, projection systems, and control software significantly impact budgets. - Regulatory compliance
Fire safety, accessibility requirements, and landlord approvals can add both time and cost.
How to budget for a commercial interior design project
A structured budgeting approach reduces financial risk:
- Define your business objectives clearly
Retail, office, and gallery spaces have very different requirements. - Decide on finish quality early
Establish whether your project is basic, mid-range, or premium. - Separate core fit-out and interactive Solutions budgets
This prevents technology costs from inflating construction estimates unexpectedly. - Allocate contingency funds
A buffer of 10%–20% is recommended for commercial projects in Singapore. - Request detailed quotations
Ensure inclusions, exclusions, warranties, and timelines are clearly stated.
Commercial interior designers: fees and value
Professional commercial interior designers do more than aesthetics. Their value lies in:
- Space planning efficiency
- Regulatory knowledge
- Cost control and value engineering
- Coordination with contractors and specialists
- Experience with Gallery Design and interactive installations
Typical design fees include:
- Percentage-based fees (8%–15%)
- Fixed design packages
- Consultancy-based pricing for specialised projects
For Interactive Gallery Design, engaging designers with proven technical experience is especially important.
Cost-saving strategies without compromising quality
- Use modular display systems for flexible gallery layouts
- Prioritise lighting design over excessive finishes
- Choose durable mid-range materials for high-traffic areas
- Design adaptable spaces that reduce future renovation costs
- Invest in scalable interactive Solutions instead of fully bespoke systems
Sample cost breakdown (1,000 sqft commercial space)
- Fit-out & finishes: SGD 100,000
- Custom carpentry & partitions: SGD 20,000
- MEP works: SGD 15,000

Figures are indicative and vary by project scope and site conditions.
Conclusion
Commercial interior design cost in Singapore depends heavily on space usage, finish level, and technical requirements. Gallery Design and Interactive Gallery Design projects require additional planning, coordination, and investment, especially when incorporating advanced interactive Solutions.
By understanding pricing structures, working with experienced commercial interior designers, and budgeting strategically, businesses can create functional, memorable spaces without overspending. Proper planning today ensures flexibility, longevity, and a stronger return on investment tomorrow.
