Direct Contractor or Interior Design Firm in Singapore: Where the Money Actually Goes
Almost every Singapore homeowner starts a renovation with the same unresolved question: do you engage an interior design firm, or go direct to a contractor? Most of the advice online answers it with adjectives — designers are "creative", contractors are "cheaper" — which helps nobody standing in a bare flat with a budget and a key collection date.
The useful way to look at it is to follow the money and the responsibility. Both routes end with the same trades doing the same physical work in your flat: a carpenter fits the carpentry, a tiler lays the tiles, a licensed electrician does the wiring. What changes is who holds the contract, who carries the risk when something goes wrong, and how many parties take a margin between your bank account and the man on site.
What a direct contractor actually is
A direct contractor is the party that carries out the works and holds the contract with you, with no agency layer in between. For HDB work that party must be an HDB Registered Renovation Contractor — we are licence number HB-09-5667H — because the licensed contractor is the one who submits the renovation permit application and is answerable to HDB for what happens in the flat.
An interior design firm sits one step up. It sells you design and coordination, then engages contractors to build it. Some design firms have in-house teams; many do not, and the trades that turn up are subcontracted. Neither arrangement is dishonest. But it does mean that on the ID route there are two businesses to pay out of one renovation budget, and only one of them is on site.
Our own published position is that going direct typically saves 15–30% against interior designer pricing, and that a designer's commission commonly runs 15–40% of the project. Those are ranges, not a promise about your job — the honest way to use them is as a reason to ask where the money goes, not as a number to quote back at anyone.
Where the margin hides in a quotation
The markup is rarely presented as a markup. It is generally already inside the line items, which is why comparing two quotations by their bottom line tells you almost nothing. Four places to look:
- Provisional sums. A line reading "carpentry — provisional $18,000" is an estimate wearing the clothes of a fixed price. It will be reconciled later, upward more often than not.
- Per-foot rates with no specification. Wardrobe carpentry on our published guide runs $200–$450 per running foot, and that spread is real: it is the difference between a plywood carcass with a laminate finish and a solid, well-hinged unit. A rate quoted without the material, thickness, hardware brand and finish named is not comparable to anything.
- Bundled "turnkey" packages. A single figure covering design, project management, materials and labour is easy to say yes to and impossible to interrogate. Ask for it to be broken out. If it cannot be broken out, that is itself information.
- Items quietly moved outside the scope. Permit fees, MCST deposits, disposal, hacking, plumbing relocation and electrical points are frequently excluded from the headline figure and reappear later as variations.
We wrote a longer piece on how to read and compare renovation quotations that goes line by line. Read it before you compare anything, not after.
What you are actually buying on each route
Going direct, you are buying build capability. In our case that means our own carpentry factory in Singapore at 19 Kaki Bukit Industrial Terrace and in-house teams for the trades, which is why a carpentry problem is a phone call rather than a negotiation between three companies. You are not buying a design service, and if you need someone to resolve a difficult layout, choose a palette and hold a coherent look across ten rooms, you should say so and budget for it.
Going through a design firm, you are buying design, coordination and a single point of contact — and that coordination has genuine value if you are overseas, working long hours, or renovating a large or complicated property. What you are not buying is a different set of trades. The men who arrive are drawn from the same pool of Singapore subcontractors either way.
The mistake is not choosing one over the other. The mistake is paying for coordination and then coordinating it yourself anyway, or going direct and then being surprised that nobody produced a mood board.
Five questions that settle it faster than any comparison table
- Who applies for the HDB renovation permit, and under whose licence number? On HDB work this must be a registered renovation contractor. Ask for the licence number and check it. If the firm you are paying is not the licence holder, you are one step removed from the party HDB actually holds responsible.
- Which trades are in-house and which are subcontracted? There is no wrong answer, but the answer tells you who you will be speaking to when a door does not close properly in month eight.
- Who fixes a defect after handover, and for how long? Get the defects period in writing, and check that the party promising it is the party that will still be under contract when you need it.
- Is the quotation itemised down to material, quantity and rate? An itemised quotation can be checked, compared and argued with. A bundled one cannot.
- What is the payment schedule tied to? Money should follow completed work. A deposit above 20% without a supplier invoice behind it, or stage payments tied to dates rather than completions, is worth pushing back on — we set this out in full in our guide to renovation payment schedules, deposits and retention.
When a design firm is the better call
Being a direct contractor does not oblige us to pretend the other route is never right. Engage a designer when the project is genuinely design-led — an unusual layout that needs resolving on paper before anyone builds it, a large landed property where the drawings carry real complexity, or a look you cannot describe but will recognise. Engage one, too, if you have no time at all and want one number to call, and you accept the cost of that convenience.
Go direct when the scope is reasonably clear — a resale flat that needs kitchen, bathrooms, carpentry and rewiring, or a commercial unit that needs to be functional and open on a date. In that situation the design content is modest, the build content is nearly all of it, and paying a coordination layer to arrange trades you could contract directly is money that could have gone into better carpentry.
For commercial premises the same decision has a slightly different shape, because reinstatement, landlord approvals and M&E provision dominate. We covered it separately in how to choose an office renovation company.
What "cheaper" should and should not mean
Direct should mean fewer parties taking a margin. It should not mean thinner materials, an unlicensed contractor, or a quotation that is lower because it quietly excludes the hacking and the permit. If one quotation is dramatically below the others, the first question is not "how are they so cheap" but "what is in the other two that is missing from this one".
Our published cost bands exist for exactly this reason — a 4-room resale flat at $35,000–$50,000 for a standard renovation, and $45,000–$65,000 for a full one, so you can see where a quotation sits before you sign anything. A figure well outside a published band, in either direction, deserves an explanation you find convincing. There is more of this in our breakdown of what a 4-room resale package actually includes.
The short version
Both routes hire the same trades. The direct route removes a margin and puts you in contract with the party doing the work; the design route buys coordination and design, and charges for it. Decide by how much design your project genuinely needs and how much of your own time you are able to give it, then check the licence number, insist on an itemised quotation, and tie the payments to completed work rather than dates.
