Singapore's renovation landscape is unique. Homes here are compact, quality expectations are high, and the line between "interior designer" and "renovation contractor" is blurry in ways that affect how much you pay and what you actually get.
Whether you're asking how much interior design costs in Singapore for a 3-bedder HDB or scoping out a full custom build for a landed home, the answer depends on several things. This guide helps you understand these factors, and puts you in more control of your budget outcome.
Average Interior Design Costs in Singapore
Interior design pricing in Singapore typically runs between $30 and $120 per square foot for the full renovation package, which includes design fees, materials, carpentry, and project management combined. But that range is wide for a reason: a 500 sqft studio with basic functional finishes and a 2,500 sqft landed home with bespoke design are simply different propositions.
Here's how the numbers look by home size and typical scope:
| Home type | Typical size | Budget range | What it usually covers |
|---|---|---|---|
| Studio / 1-bedder | 400–600 sqft | $30k – $60k | Functional layout, standard finishes, essential carpentry |
| 2–3 bedrooms | 800–1,300 sqft | $60k – $120k | Full renovation with mid-range materials, custom carpentry |
| 4-bedroom / executive | 1,300–1,700 sqft | $100k – $180k | Higher specification, more rooms, more built-ins, cosmetic wetworks |
| Landed / bespoke | 2,000 sqft+ | $200k – $500k+ | Custom design, premium finishes, structural changes, interior and/or exterior |
Beyond size, the type of design package you choose shapes the budget significantly. Here's how the three main tiers compare:
| Basic | Mid-range | Premium |
|---|---|---|
$30 – $50 psf
|
$50 – $80 psf
|
$80 – $120+ psf
|
Common misconception: More expensive does not always mean better quality, and cheaper does not always mean worse. Interior design fees in Singapore vary widely because some firms carry high overheads, others use premium marketing to justify standard work, and others deliver exceptional results at mid-range prices. The numbers are a starting point, not a verdict.
What's Actually Included in Interior Design Costs
When designers quote you a number, it helps to know what that number is supposed to cover. Most full-service interior design packages in Singapore bundle four main components:
| A. Design fees | B. Materials & finishes |
|---|---|
| The thinking, not just the doing Concept creation, space planning, and technical drawings. This includes mood boards, material specifications, and site visits for measurement and supervision. Some firms charge design fees separately, while others bundle them into the overall package. Either way, expect design to account for roughly 10–15% of the total interior design cost in Singapore. | Where quality differences show up most Flooring, wall treatments, tiles, and cabinetry finishes. Entry-level materials come from locally available laminates and standard tiles. Mid-range introduces textured surfaces, engineered timber, or feature walls. Premium reaches into imported stone, large-format tiles, and custom-finished surfaces. Materials typically account for 25–35% of your total budget. |
| C. Furnishing & décor | D. Project management |
| Built-in vs loose Custom built-ins (wardrobes, TV consoles, study desks) are priced into the carpentry scope. Loose furniture — sofas, dining tables, beds — may or may not be included depending on your package. Always clarify this upfront. Designers who source and style loose furniture add value. Those who leave it out of scope leave a gap in your budget plan. | The invisible cost that matters Contractor coordination, timeline management, delivery scheduling, and QC at handover. A well-managed project saves money by catching problems early and keeping trades on schedule. A poorly managed one creates delays and rework that cost far more than the management fee would have. This component is easy to undervalue, until something goes wrong. |
Key Factors That Drive Price Variation
Two homeowners with the same size flat can receive quotes that differ by S$40,000 or more. These are the variables doing most of the work:
| Factor | Cost Impact |
|---|---|
| Structural works (hacking, wet areas) | High |
| Custom carpentry vs modular solutions | High |
| Material quality tier | High |
| Space size and layout complexity | Medium |
| Imported brands or bespoke items | Medium |
| Number of rooms in scope | Lower |
Structural works deserve a special mention. Hacking walls, relocating wet points, or reconfiguring bathrooms adds cost and timeline in ways that are hard to predict upfront. If your brief includes any of these, build a wider contingency buffer from the start.
How to Budget Realistically
Set your total renovation budget before you speak to any designer. Walking in with a defined number puts you in control of the conversation — designers who know your ceiling can scope accordingly, rather than designing upward and trimming down.
A practical way to allocate your budget across the main categories:
| Category | Recommended allocation | Notes |
|---|---|---|
| Design fees | 10–15% | Higher for fully custom or complex briefs |
| Materials & finishes | 25–35% | The biggest lever for quality perception |
| Carpentry & built-ins | 20–30% | Custom builds command a premium |
| Loose furniture & décor | 15–25% | Easy to overspend without a clear list |
| Contingency buffer | 10–15% | Never skip this, especially for older homes |
When comparing quotes, make sure you're comparing the same scope. One firm's S$80,000 may include full furniture sourcing and styling. Another may cover only the renovation works. Ask each firm to specify exactly what their number does and does not include — then align the comparison before making a decision.
Ways to Save Without Sacrificing Style
- Prioritise functional zones first. Spend where it matters most — the kitchen, bathrooms, and living areas that get the most daily use and have the biggest impact on how the home feels. Bedrooms can often be handled more simply without anyone noticing.
- Mix premium focal pieces with simpler elements. One standout feature — a stone island, a textured feature wall, a statement light fixture — elevates the whole space. Pair it with cleaner, plainer elements and the focal piece does the talking.
- Reuse and upcycle selectively. Not everything needs replacing. A well-made sofa can stay; dated handles and fittings can be swapped cheaply. Bring in your existing inventory early in the design conversation so your designer can work around keepers rather than quote a full replacement.
- Choose space-efficient solutions for smaller homes. In Singapore's compact apartments, built-ins that double as storage, foldable fixtures, and multi-functional furniture deliver more value per dollar than decorative items. Good space planning costs less than adding square footage you don't have.
