Office Renovation in Singapore: The Complete Planning and Cost Guide

Office renovation in Singapore typically costs somewhere between S$40 and S$150 per square foot for a standard fit-out, so a 2,000 sqft office often lands in the S$80,000 to S$300,000 range depending on finish level, M&E works, and how much you rebuild versus refresh. A realistic timeline runs 6 to 12 weeks once design is locked, and you should budget separately for professional submissions, permits, and reinstatement at lease end. The biggest cost swings come from partitions, electrical and air-con reconfiguration, ceiling and flooring, and whether your building or landlord requires a Qualified Person (QP) submission.

This guide walks a Singapore business owner or office manager through the real decisions: what drives the price, which approvals actually apply, how long it takes, and how to avoid the classic mistakes that blow the budget. Numbers here are practical ranges, not fixed quotes, because every unit, landlord, and scope is different. Treat them as planning anchors and confirm the specifics with a licensed contractor once your layout is drawn.

How much does an office renovation cost in Singapore?

Cost is driven mostly by scope per square foot. A light refresh (paint, carpet, minor partitions, existing air-con and power reused) sits at the lower end, while a full strip-and-rebuild with new M&E, glass partitions, and custom joinery pushes toward the top. Grade A CBD offices generally cost more than heartland or industrial-zone units because of building requirements and access restrictions.

Use these rough per-square-foot ranges as a starting point, then adjust for your building and finish level:

• Basic refresh (paint, flooring, light partitions): around S$40 to S$60 per sqft
• Standard fit-out (new partitions, ceiling, lighting, some M&E): around S$60 to S$100 per sqft
• High-end or full rebuild (glass fronts, custom joinery, full M&E, AV): around S$100 to S$150+ per sqft
• Add-ons priced separately: professional/QP submissions, permits, licensed electrical work, air-con relocation, data cabling, and end-of-lease reinstatement

What approvals and permits do you need?

Most office fit-outs need some form of regulatory or landlord approval, and skipping it is the fastest way to fail an inspection or lose your deposit. If you touch fire safety provisions (sprinklers, smoke detectors, exit routes, fire-rated walls) you generally need a Qualified Person to submit plans to the SCDF, and works affecting the building structure require a Professional Engineer or Architect submission to the BCA. Landlords in commercial buildings almost always require their own approval of contractor, drawings, and insurance before any work starts.

Common approvals to check before you begin:

• Landlord / building management approval of layout, contractor, and work hours
• SCDF fire safety submission via a Qualified Person if you alter sprinklers, detectors, or escape routes
• BCA submission by a PE or Architect if structural or facade works are involved
• Licensed Electrical Worker sign-off for any changes to the electrical installation, and a licensed plumber for water and drainage changes
• URA use approval if the premises' approved use is changing (for example, from warehouse to office)

How long does an office renovation take?

For a typical small-to-mid office of 1,000 to 3,000 sqft, plan on 6 to 12 weeks of on-site work after the design is finalised and permits are in hand. Design, quotation, and approvals often take another 3 to 6 weeks before that, so the honest end-to-end figure from first meeting to move-in is usually 2 to 4 months.

Timeline drivers to plan around:

• Design and quotation: 2 to 4 weeks to finalise layout, materials, and a firm price
• Approvals and QP submissions: 1 to 4 weeks depending on scope and building
• Construction: 4 to 10 weeks for partitions, ceiling, flooring, electrical, and air-con
• Restricted work hours in many commercial towers (evenings or weekends only) can stretch the on-site period

What are the main cost items to budget for?

Understanding where the money goes helps you cut the right corners. In most office fit-outs, partitions and ceiling works, electrical and air-con, and flooring make up the bulk of the spend, while loose furniture and AV are often quoted separately.

A typical office renovation budget breaks down roughly like this:

• Partitions, glass fronts, and doors: often the single largest line
• Ceiling, lighting, and electrical works: rewiring, new points, LED fittings
• Air-conditioning: relocating or adding cassette or ducted units for the new layout
• Flooring: carpet tiles, vinyl, or raised access flooring
• Wet works: any pantry, sink, or toilet changes needing plumbing
• Painting, finishes, and signage
• Professional fees, permits, and end-of-lease reinstatement

How do you plan an office renovation that passes inspection?

Start with the lease and the landlord's fit-out manual, because those documents set the rules you must design around: work hours, protection of common areas, insurance, and reinstatement obligations at the end. Lock your layout early, then confirm which trades need licensed sign-off so that electrical, fire safety, and plumbing works are done and certified correctly rather than reworked later.

A clean planning sequence looks like this:

• Confirm approved use and lease terms, including reinstatement clauses
• Finalise floor plan and headcount so partitions and power are right the first time
• Get a detailed, itemised quotation rather than a lump sum
• Line up QP, PE, or licensed worker submissions before site work starts
• Schedule licensed electrical and plumbing works, and keep the certificates for handover and audits

Should you hire a contractor or an interior designer?

For a straightforward office refresh, a competent renovation contractor who handles building works, electrical, and air-con can deliver the whole job. For a more ambitious space with branding, complex layouts, or multiple trades, an interior designer or design-and-build firm coordinates the look while a main contractor executes, which reduces finger-pointing when something goes wrong.

Whichever route you choose, a single accountable contractor who covers the renovation, electrical, and plumbing under one roof keeps the timeline tight and the approvals coordinated. If you want the building works, wiring, and wet works handled together by a licensed team, that is exactly the kind of end-to-end renovation service worth engaging early, before you sign the lease, so the fit-out is scoped realistically from day one.

Frequently asked questions

Do I need SCDF approval for an office renovation? You need an SCDF fire safety submission through a Qualified Person only if your works affect fire safety provisions such as sprinklers, smoke detectors, fire-rated walls, or escape routes. A purely cosmetic refresh that leaves these untouched usually does not, but always confirm with your contractor and building management first.

Who pays for reinstatement at the end of the lease? In most Singapore commercial leases the tenant pays to reinstate the unit to its original bare or handover condition. Budget for this from the start, because a heavy fit-out can mean a significant reinstatement bill later; check the exact clause in your lease.

Can I renovate an office while staff are still working there? Sometimes, if the work is phased and noisy or dusty tasks are scheduled after hours, but many commercial buildings restrict renovation to evenings and weekends anyway. For anything beyond a light refresh, a temporary decant or staged plan is usually cleaner and safer.

How accurate are per-square-foot estimates? They are planning anchors, not quotes. Your real price depends on your building, finish level, how much M&E you reconfigure, and current material and labour costs, so always get an itemised quotation against your actual floor plan before committing.
