How Much Office Renovation Actually Costs in Singapore (2026 Breakdown)

"How much does office renovation cost" doesn't have a single answer, because "office renovation" covers everything from repainting and re-carpeting a small SME unit to a full commercial fit-out with new M&E, partitions, and a completely reworked floor plan. The honest answer is: it depends on scope, and scope is usually decided by what condition your unit is in when you take it over, not just what you'd like it to look like.

Here's a realistic breakdown by project type, and what actually moves the number.

The Three Common Scopes

Cosmetic refresh Paintwork, flooring replacement, updated lighting fixtures, new furniture — no changes to layout, partitions, or M&E. This is the fastest and least expensive category, suited to offices that just need to feel current without operational disruption.

Partial fit-out New partitions, some layout changes, upgraded meeting rooms or breakout areas, and targeted M&E work (additional power points, revised lighting zones). This is the most common scope for growing SMEs adjusting their space to a new headcount or way of working.

Full fit-out Complete layout redesign, full M&E overhaul, new ceiling and flooring systems, and often submissions to the building management or authorities depending on the scale of work. This is typical for a bare-shell or "cold shell" unit, or a business relocating into a space that doesn't suit its operations at all.

What Actually Drives Cost Up

Three factors matter more than square footage alone:

Unit condition on handover. A bare-shell unit costs more to fit out than a unit with existing ceiling, flooring, and basic M&E already in place — similar to the BTO-versus-resale dynamic in residential renovation. Ask what condition your unit is being handed over in before budgeting.

M&E complexity. Additional power points, data cabling, air-con zoning changes, and lighting redesigns add up faster than most first-time tenants expect, especially in older buildings where existing capacity is limited.

Authority and building submissions. Larger-scope works, especially those affecting fire safety systems or building services, may require submissions through your building management or relevant authorities — this affects both cost and timeline, not just paperwork. See our First-Time Tenant's Renovation Checklist for what to check with your landlord before signing.

A Realistic Way to Budget

Rather than anchoring to a per-square-foot number pulled from a different project's scope, budget by working backward from what you actually need:

1. Start with your unit's current condition (bare shell, existing fit-out, partial fit-out)

2. Decide your scope tier (cosmetic, partial, full) based on how much of that existing condition needs to change

3. Add contingency — 10-15% is reasonable for partial or full fit-outs, where M&E surprises are most common

4. Get itemised quotes, not a single lump sum, so you can see where budget is actually going

Where SMEs Often Overspend — and Underspend

We regularly see SME clients over-budget on visual finishes (feature walls, branded signage) while under-budgeting on the things that actually affect daily work — acoustic treatment, adequate power point placement, and lighting suited to screen-based work. Our guide to designing for focus covers where acoustic and spatial investment tends to pay off more than decorative spend. For smaller footprints specifically, see Small Office, Big Impact for where budget matters most at limited scale.

Getting an Accurate Number for Your Space

At Skai Atelier, we start office projects with a site assessment before quoting — because unit condition and M&E complexity affect cost more than finish choices do. This is part of our office and commercial interior design process from first consultation onward.
