You've just collected your keys. The first call you make is to an interior design firm. They visit, nod enthusiastically at your Pinterest board, and a week later email you a quote: S$95,000 for a 4-room HDB.
The shock is real. Singapore renovation costs have climbed steadily — partly post-pandemic supply chain effects, partly contractor labour shortages, but mostly because local interior design (ID) firms have built an opaque markup model that most homeowners never see through. The good news: the alternative is now accessible, transparent, and protected by escrow.
What Does a 4-Room HDB Actually Cost?
A standard 4-room HDB in Singapore runs approximately 90–105 m² of floor area. A full renovation typically covers carpentry, flooring, kitchen, two bathrooms, painting, electrical works, and miscellaneous items like feature walls and false ceilings. Below is a category-by-category comparison of what a conventional Singapore ID firm charges versus what the same work costs when sourced factory-direct via OriginSpace.
| Category | Local ID Firm | OriginSpace | You Save |
|---|---|---|---|
| Custom Carpentry (full-home) | S$18,000–28,000 | S$9,000–14,000 | ~50% |
| Flooring (vinyl plank, 90m²) | S$6,000–10,000 | S$2,800–4,500 | ~54% |
| Kitchen Cabinetry & Countertop | S$12,000–20,000 | S$5,500–9,000 | ~55% |
| Bathrooms × 2 (tiles + fittings) | S$10,000–16,000 | S$4,500–7,500 | ~54% |
| Painting (full-home) | S$3,500–5,500 | S$1,800–2,800 | ~49% |
| Electrical & Lighting | S$5,000–8,000 | S$3,000–5,000 | ~38% |
| Miscellaneous & Contingency | S$4,000–8,000 | S$2,000–4,000 | ~50% |
| Total Range (est.) | S$59,500–95,500 | S$28,600–46,800 | ~40–52% |

Where Does the Money Go? Breaking Down the Markup
When you pay a local ID firm S$95,000 for a 4-room renovation, you are not paying S$95,000 worth of labour and materials. You are paying a markup chain that typically looks like this:
Factory price (China)
Kitchen cabinet set: RMB 8,000 ≈ S$1,500
China trading company markup
+20–30%: S$1,800–S$1,950
Singapore distributor markup
+30–50%: S$2,340–S$2,925
ID firm showroom & project management markup
+40–60%: S$3,276–S$4,680
That kitchen cabinet that left the Chinese factory for S$1,500 arrives in your HDB priced at S$4,680 — a 212% markup. Multiply this across every item in your renovation and the numbers become staggering. The local ID firm is not evil; this is simply how the traditional supply chain operates. The question is whether you want to keep funding it.
The 'lump sum quote' trap
The OriginSpace Approach: Factory-Direct to Your Door
OriginSpace is a cross-border renovation marketplace that connects Singapore homeowners directly to KYC-verified designers and suppliers in China, with sea freight handled by Logify and payments held in SGD escrow. There are no Singapore distributors, no ID firm showroom overhead, and no lump sum quotes.
Here is what the supply chain looks like on OriginSpace:
China Factory
KYC-verified, with QC photos before shipment
Logify Sea Freight
Tracked LCL shipping, China → Singapore port
SG Contractor
Verified local installers, paid in SGD
Your payment never goes directly to the factory until you have confirmed receipt and quality. Funds are held in SGD escrow by OriginSpace and released in milestone payments — 30% on order confirmation, 70% before the China warehouse releases cargo for sea freight. This means you never lose your deposit if a supplier goes dark.

The saving at a glance
What About Quality?
This is the most common objection. Singapore homeowners have been conditioned to associate "China-made" with inferior quality — a perception that is both outdated and, frankly, exploited by local ID firms to justify their margins.
The factories that supply OriginSpace's verified designers are, in many cases, the same factories supplying the local ID firms. The difference is that when you go through OriginSpace, you see the actual factory certificate, the QC inspection photos taken before shipment, and the real specification sheet — not a polished showroom sample with an inflated price tag.
KYC-Verified Suppliers
Every designer and supplier on OriginSpace submits national ID, business license, and export license. Admin-reviewed and approved before listing.
Pre-Shipment QC Photos
Suppliers upload inspection photos of finished goods at the China warehouse before any freight is booked. You approve before it ships.
Milestone Escrow
30% held until production complete. 70% released only when you confirm goods are at the China warehouse. SGD held, never sent to supplier early.
7-Day Dispute Window
Receive your goods and find a defect? Raise a dispute within 7 days of delivery. Platform mediates and escrow holds until resolved.
There is a genuine trade-off to acknowledge: the end-to-end project management hand-holding of a local ID firm is not replicated here. On OriginSpace, you are more involved in the process — reviewing proposals, approving materials, coordinating your contractor. For homeowners who value control and transparency, this is a feature, not a bug. For those who genuinely want a fully hands-off experience, a premium ID firm may still make sense — just go in with open eyes about what you are paying for.
