If you’ve started getting quotes for an office renovation, you’ve probably noticed that prices vary wildly — and contractors rarely explain why. This guide breaks down what office renovation actually costs in Singapore in 2026, what drives those numbers, and what to watch out for when budgeting.
What Is the Average Office Renovation Cost in Singapore?
There is no single “average” — office renovation costs in Singapore depend on size, condition of the existing space, scope of work, and finish level. That said, here’s a realistic ballpark to work from:
| Scope | Cost per sq ft | Typical Budget (1,500 sq ft) |
|---|---|---|
| Basic fit-out (cosmetic refresh) | $30 – $60 | $45,000 – $90,000 |
| Standard office renovation | $80 – $130 | $120,000 – $195,000 |
| Full design-and-build | $150 – $250+ | $225,000 – $375,000+ |
These figures are for commercial spaces in Singapore’s CBD and business parks. HDB shophouse conversions and industrial units may come in lower on PSF but involve additional compliance and structural considerations.
What Drives Office Renovation Costs?
1. Size and Layout Complexity
Larger floor plates cost less per square foot — economies of scale apply. But unusually shaped spaces, split levels, or units with structural columns add design and construction cost. If your space requires structural works, factor in an additional 10–20% buffer.
2. Scope of Work
Renovation costs spike when the scope moves beyond cosmetic changes. The three biggest cost drivers are:
- M&E works — electrical, air-conditioning, and data cabling. If your space is new or recently reinstatement-restored, M&E can be kept lean. Old legacy wiring needs a full replacement.
- Partition walls — glass partitions cost $200–$400 per linear metre. Drywall is cheaper but limits acoustic performance.
- False ceilings and lighting — exposed ceilings are on-trend and cut cost. Grid ceilings with recessed lighting add $15–$30 per sq ft to the job.
3. Finish Level
A standard office renovation uses commercial-grade carpet tiles, vinyl flooring, and basic joinery. A premium finish — solid surface counters, frameless glass, feature walls, designer lighting — can add 40–60% to the budget. Consider your brand and the impression you want clients and staff to walk into.
4. Design Fees
If you engage a separate interior designer and then a contractor, expect to pay 8–15% of the project value in design fees on top of construction costs. A design-and-build contractor like RH Design & Build combines both under one contract — saving both time and the fee gap.
5. Timeline Pressure
Fast-tracked renovations — especially if you’re working around lease-hand-back deadlines — cost more. Overtime labour, split-shift crews, and expedited material orders all carry premiums. Plan at least 8–12 weeks for a standard 1,000–2,000 sq ft office renovation.
Hidden Costs Business Owners Often Miss
- Building approval fees — most commercial renovations require a permit from your landlord and sometimes BCA. Budget $1,500–$5,000 depending on complexity.
- Reinstatement clause — if you’re renovating a leased space, check your tenancy agreement. Many landlords require you to restore the unit to bare condition when you leave. Build this into your long-term cost picture.
- Furniture and fittings — renovation quotes typically exclude loose furniture. A 1,500 sq ft office with 20 workstations can easily add $30,000–$80,000 in furniture costs.
- IT and AV setup — network points, server room cooling, and boardroom AV are specialist trades not always included in a standard renovation quote.
Pro Tip: Always ask contractors to quote in a detailed line-item format — not a lump sum. If a quote comes as a single number, you have no way to compare or negotiate. At RH Design & Build, every quotation is broken down by trade so clients know exactly where their money goes.
How to Keep Office Renovation Costs Under Control
Twenty years in commercial renovation has taught us a few things that consistently save clients money without compromising the outcome:
- Fix your brief before getting quotes. Scope changes mid-project are the fastest way to blow a budget. Know your headcount, growth plans, and must-haves before speaking to contractors.
- Don’t over-specify common areas. Invest in the spaces clients see — reception, boardroom, collaboration zones. Back-of-house areas like pantries and server rooms can be value-engineered without anyone noticing.
- Choose a design-and-build firm. Separating design and construction creates a coordination gap where costs slip through. A single design-and-build contract locks in the price earlier and reduces variation orders.
- Move fast on procurement. Material prices fluctuate. Once your design is approved, don’t sit on it — delays between approval and construction start often result in higher costs if material prices shift.
Getting an Accurate Quote for Your Office Renovation
The most accurate way to budget an office renovation is to get a measured quote on your actual floor plan — not a PSF estimate. Every space has quirks: odd angles, legacy M&E, structural beams, or building restrictions that a PSF number can’t capture.
