Commercial interior design costs in Singapore: fees, fit-out and budgeting

A practical guide to commercial interior design costs in Singapore: how design fees work, what fit-out benchmarks show, and what drives real project cost.

Two cost lines are commonly confused when commercial interiors are budgeted: the design consultancy fee, which pays for design, documentation and agreed construction-stage support, and the fit-out budget, which pays for the physical delivery of the space. They are different numbers, set by different things, and treating them as one is a recurring cause of misaligned briefs. This guide explains how design fees are structured in Singapore, what published benchmarks say about fit-out costs, what moves real project cost, and how to judge when a full consultancy appointment makes sense.

Key takeaways

The design consultancy fee and the fit-out budget are separate cost lines, and they are frequently confused when projects are budgeted.
Studio X prices each appointment against its scope, quoting staged lump-sum fees rather than a published standard rate.
For an external reference point, Cushman & Wakefield's 2026 guide gives an indicative all-in office fit-out benchmark of SGD 180 per sq ft for a collaborative specification (market conditions as of December 2025; offices only).
Handover condition, specification and programme materially affect what a project really costs.
A full consultancy appointment suits projects that genuinely need that level of design and coordination.

How design consultancy fees work

Studio X quotes staged lump-sum fees against an agreed scope, with payments tied to project stages: concept design, schematic and detailed design, tender documentation, and agreed construction-stage support. The fee varies with scope, complexity, programme and the level of construction-stage involvement required, so each appointment is priced against the brief rather than a published standard rate.

Whatever firm you speak to, a clear fee proposal should state plainly what each stage delivers, what is excluded, and how payments are staged. That document is the basis on which fees can be compared fairly, and it is reasonable to expect clarity in it.

The variables that move a design fee are worth knowing because they are also levers you control. Scope is a major factor: design only, or design through tender and construction-stage support. Complexity is another: a compact restaurant with bespoke joinery can carry more design hours than a much larger open-plan office. The number of stakeholders and approval rounds matters, and so does programme pressure, since a compressed timetable concentrates senior time.

Client-side governance and resource expectations also affect the fee. A detailed brief, clear decision rights and an efficient escalation path reduce uncertainty and help limit unnecessary design iterations. Conversely, extended approval chains, frequent whole-team meetings or sustained director-level involvement require more senior resource and should be reflected in the scope of the appointment.

This is not about limiting access. It is about matching the project team and meeting structure to the decisions being made. Where senior decisions can be resolved efficiently at the appropriate level and then communicated clearly through both teams, the consultancy can usually be resourced more efficiently.

What does the fit-out itself cost?

For office fit-out cost benchmarks, use published data rather than any design firm's estimate, including ours. Cushman & Wakefield's Office Fit Out Cost Guide 2026 gives an indicative all-in benchmark of SGD 180 per sq ft for a collaborative-specification Singapore office fit-out, with a retrofit average of SGD 81 per sq ft and an office reinstatement average of SGD 24 per sq ft. All-in is the operative phrase: C&W's methodology includes furniture, M&E works, builder works, AV/IT and other fit-out costs, so the figure is broader than a contractor's construction price alone. The figures reflect market conditions as of December 2025, and C&W describes them as indicative benchmarks rather than fixed project costs; the full specification breakdown is in the guide itself.

Two cautions when using any benchmark. First, these are office figures: retail, restaurant and other commercial interiors behave differently, and an office number should not be transplanted into those budgets. Second, cost benchmarks are only useful when their scope is understood. Different reports package project costs differently, so check the methodology before comparing a benchmark against a contractor quotation or a total project budget.

Singapore specifics worth budgeting for

In Singapore, the handover condition set by the landlord shapes the budget before design begins: a bare-shell unit, a partially fitted unit and a previously occupied space carry different starting costs.

Where the lease requires reinstatement, that obligation should be considered from the outset rather than treated as a lease-end surprise. For offices, C&W's 2026 guide gives an indicative Singapore reinstatement average of SGD 24 per sq ft.

Depending on the building and landlord, fitting-out requirements can affect programme and cost, including plan approvals, access restrictions and permitted working hours. Depending on the works, statutory approvals may also apply: a change of use may require planning permission from URA, some building works require BCA approval while minor works are exempt, and fire-safety works may also require SCDF plan approval, subject to the applicable exemptions. Links to the official guidance are at the end of this article.

Design-and-build is another procurement route available in Singapore, packaging design and construction within one appointment. It distributes cost, control and accountability differently from a consultancy-plus-contractor route, and the comparison is worth making consciously rather than on the headline price alone.

‍

What makes the numbers increase?

In our experience across Singapore projects, five cost drivers recur frequently:

Handover condition. What the landlord hands over strongly influences how much of the budget goes into enabling or replacement works.
How much of the existing space you can keep. Retaining serviceable ceilings, flooring and services is a significant cost lever in refurbishments; stripping out and starting again is sometimes right, but should be a decision, not a default.
Specification density. Joinery, finishes, lighting and detailing separate a serviceable fit-out from a brand-defining one, and two projects of similar size can differ materially in cost for this reason alone.
Programme. Compressed programmes can increase cost through overtime, constrained sequencing and reduced procurement flexibility. Studio X delivered Eastern Pacific Shipping's 10,000 sq ft Singapore headquarters at Millenia Tower from concept to completion across an eight-month programme.
Late changes. Changes made after construction begins are generally more expensive than resolving the same decisions during design.

Design decisions shape more than cost. At Latitude at ONE°15 Marina, pulling the frontage back by one metre created more usable terrace space for the restaurant. At the Singapore Cricket Club, the Oval Restaurant & Verandah was redesigned within an operating heritage clubhouse. Decisions of that kind are made in the design phase, which is why the design phase repays attention.

When is a full consultancy appointment worthwhile?

A full-scope consultancy suits projects where the outcome depends on design quality and coordination: customer-facing environments where the space does commercial work, projects with multiple stakeholders, briefs where operations and brand have to be reconciled in the plan, projects where landlord or statutory approvals are required, and projects where resolving decisions before contractors price them will improve pricing clarity.

It is the wrong purchase in some situations, and it is better to say so here. If you have a completed design and want construction quotations, you need contractors, not a consultancy. If you need technical drawings only, with the design decisions already made, a drafting service may be the more appropriate appointment. If the work is a small cosmetic refresh, a full appointment may be disproportionate. And we have declined projects where the fit-out budget could not deliver the quality the client described; it is better to hear that at a first meeting than after the lease is signed.

What to prepare before asking for fees

Fee proposals get sharper and easier to compare when you can provide: the unit's address and handover condition, or the shortlist if you have not signed; an honest total budget range, even a wide one; the distinction between your non-negotiables and preferences; the date the space must be earning; and who on your side can make decisions. A designer who asks detailed questions about these at the first meeting is showing you how they will manage your budget later.
