# Renovation Design in Singapore: What It Should Cost, and Why **By Joy David** ยท 2026-06-17 A typical Singapore renovation quote will arrive as a multi-page document with line items for hacking, plastering, electrical, carpentry and a design fee somewhere near the top. That fee is not the whole cost of renovation design. The real cost is the sum of every decision made inside that document, and the furniture budget left over once it is signed. This article breaks down how renovation design fees are structured in Singapore, where money tends to disappear quietly, and why the furniture choices you make after works finish matter just as much as anything in the ID contract. Interior design fees in Singapore typically run as a percentage of total project value, a fixed lump sum, or are bundled into carpentry markups. For a standard HDB 4-room flat of around 90 sqm, full-service ID projects commonly range from mid to premium tiers. The smarter question is not what the fee line says, it is how much is left for furniture, and whether those two budgets were ever planned together. ## What "Renovation Design" Actually Covers ![Renovated Singapore condo living room with sectional sofa, coffee table, lounge chair, curtains, and warm wood feature wall.](https://cdn.shopify.com/s/files/1/1805/8667/files/singapore-renovation-design-sofa-living-room-layout.jpg?v=1781663070) The phrase gets used loosely. At the lighter end, a renovation designer produces a floor plan, a mood board, and a carpentry layout, then manages contractors. At the heavier end, a full-service interior designer conducts site measurements, produces detailed technical drawings, sources all materials, specifies every fixture and fitting, and holds your hand through every site visit. Both are legitimate services. What differs enormously is what you are paying for and what you are expected to bring yourself, furniture being the most common gap. ### Design-and-build versus fee-only Most Singapore ID firms operate on a design-and-build model: the fee is partly absorbed into the renovation works, with margin built into carpentry and subcontracted trades. A fee-only designer charges a transparent consultation or project-management fee but leaves procurement to you. Neither model is inherently better, but they create very different financial pictures. In a design-and-build arrangement, savings come from negotiating the works package; in a fee-only arrangement, savings come from your own sourcing. ### What the fee rarely includes Loose furniture (your sofa, dining table, bed frame, mattress, wardrobe) is almost never included in an ID contract unless you have specifically asked for a full-furnishing package. This is the number that catches people. A renovation project can be completed, beautiful, and utterly empty in ways that cost another substantial sum to fix. ## How Design Fees Are Structured, and Where They Balloon There are three common fee structures in Singapore: - **Percentage of project cost**, typically a stated percentage applied to total renovation works. On a larger project this adds up quickly. - **Fixed project fee**, a lump sum agreed upfront, sometimes tiered by flat type or scope. - **Bundled into carpentry**, the most common and the least transparent; design appears "free" because the margin is baked into the per-unit cost of built-in cabinetry. The bundled model rewards homeowners who can compare carpentry quotes line by line. It also means that the more built-in carpentry you commission, the higher the effective design cost. This matters because every dollar spent on bespoke carpentry is a dollar not available for the freestanding furniture that actually defines how a room feels to live in. ### The carpentry trap Built-in carpentry is genuinely useful: a floor-to-ceiling wardrobe at 58-60 cm depth maximises a bedroom, a full-height TV wall keeps cables hidden, and custom joinery in an awkward corner solves problems no off-the-shelf piece can. But carpentry is also the easiest line to keep expanding in a renovation quote, because each addition feels incremental. A second display cabinet here, a feature wall there. By the time the contract is signed, the carpentry budget has consumed a large share of available funds, and the furniture line reads "homeowner to supply." Carpentry cannot be moved when you shift house. Furniture can. That asymmetry is worth carrying into every budget conversation. ## The Furniture-Renovation Gap Nobody Warns You About Here is the part that tends to surface only after keys are collected: renovation works can finish on time and on brief, the space can look polished in the handover photos, and still feel uncomfortable to live in because the furniture chosen under budget pressure does not match the quality of what surrounds it. Low-density foam sofa cushions in a beautifully tiled living room. A particleboard bed frame in a bedroom with freshly painted accent walls. Both will age faster than their surroundings, and both will need replacing sooner than the renovation itself will. The design coherence that the ID contract promised quietly unravels. The gap is not a failure of taste. It is a failure of budget planning: treating renovation and furniture as two separate exercises rather than one allocation problem. ### Sizing the gap early A rough way to sense-check: list every room and every piece of loose furniture it needs. For a 4-room HDB at approximately 90 sqm, that typically means a living set (sofa, coffee table, TV console), a dining set, two to three bedroom setups (bed frame, mattress, wardrobe at minimum), and a study area if needed. Priced at mid-tier, this is a material sum. If that sum does not appear anywhere in your renovation budget, the gap is real and it will land at the end of the project when your spending energy is already exhausted.

These are genuinely costly to redo. 2. **Mattress and bed frame**, you spend roughly a third of your life on your mattress. A well-supported sleep surface on a sturdy frame is not an indulgence, it is the highest-use piece in the home. **[The bedroom furniture range](https://megafurniture.sg/collections/bedroom)** covers everything from the frame to the full sleep setup. 3. **The main social piece**, in most Singapore homes this is the sofa. A sofa with a seat depth of 55-65 cm in a good fabric or top-grain leather will outlast several budget alternatives and anchor the living room convincingly. 4. **Carpentry only where freestanding cannot solve it**, awkward corners, maximising storage height in a smaller bedroom, concealing pipes. Where an off-the-shelf wardrobe fits, it usually costs less, can be replaced, and travels with you. The living room is where guests spend time and where coherence is most visible. **[Living room furniture](https://megafurniture.sg/collections/living-room-furniture)** chosen before renovation works are finished means you can confirm piece sizes against actual room dimensions rather than guessing from drawings. ## How to Judge Value, Not Just Price ![Open-plan Singapore home with sofa, dining set, built-in storage, and natural light after renovation design.](https://cdn.shopify.com/s/files/1/1805/8667/files/open-plan-renovation-design-singapore-furniture-planning.jpg?v=1781663070) A cheaper renovation design fee is not automatically better value if it produces a space that requires costly furniture compromises to complete. Equally, a premium ID fee is not automatically justified if most of the budget goes to carpentry you will abandon at the next move. A few useful tests: ### Ask what the furniture budget is, explicitly Any ID worth working with will have thought about the furniture that will occupy the space. If the answer is vague or deferred, that is a sign the design exists as a rendering, not as a lived room. ### Check material specifications honestly Engineered wood and plywood are stable, good-value choices for carpentry. Particleboard is budget-grade and vulnerable to moisture at edges, which matters in Singapore's humidity (typically 70-85%). Solid wood is durable and refinishable but moves with humidity. Ask for the substrate, not just the finish. The same logic applies to furniture. A solid-wood dining table can be sanded and refinished if it marks. A particleboard one cannot. For a dining room that hosts family dinners regularly, that distinction compounds over years. **[The dining furniture collection](https://megafurniture.sg/collections/dining-room)** includes options across material tiers, with actual specifications listed per piece. ### Think about the second move Singapore homeowners move more than once. BTO to resale, HDB to condo, upgrading over a decade. Furniture travels; built-in carpentry does not. Every dollar of budget you hold back from bespoke joinery and put into quality freestanding pieces is a dollar of value that follows you to the next home. ## Frequently Asked Questions ### Is an interior designer necessary for an HDB renovation in Singapore? No. HDB renovations can be managed directly through licensed contractors without an ID. A designer adds value in space planning, material coordination, and managing multiple trades. For straightforward works (repainting, flooring, replacing fixtures) a competent contractor and your own furniture choices can achieve strong results at lower total cost. The question is whether the complexity of your brief justifies the fee. ### How do I avoid overspending on built-in carpentry? Set a carpentry ceiling before you meet any ID, and hold it. For each carpentry piece proposed, ask whether a quality freestanding alternative exists that solves the same problem. Wardrobes, TV consoles, bookshelves, and study desks are all available off-the-shelf in sizes and finishes that suit most rooms. Reserve bespoke carpentry for genuinely awkward geometry or infrastructure that cannot be addressed otherwise. ### When should I buy furniture relative to my renovation timeline? Shortlist and size furniture during the renovation planning phase, before carpentry is finalised. This lets you confirm that built-in dimensions accommodate the furniture you intend to place near them, a sofa that fits the living wall, a bed frame whose headboard clears the aircon ledge, dining chairs that pull out without hitting the kitchen counter. Buying after handover risks either ill-fitting pieces or expensive carpentry changes. ### Does renovation design affect my furniture choices? Yes, in two ways. First, the style language established by material and colour choices in the renovation (flooring tone, wall finish, cabinetry style) constrains which furniture reads coherently in the space. Second, the clearances built into the renovation layout (how wide a walkway is left, where power points land) determine the maximum and minimum furniture sizes that work. Settling the renovation layout and the furniture shortlist at the same time prevents both problems. ### What is the biggest mistake homeowners make with renovation budgets? Treating renovation and furniture as sequential decisions. Most people sign the renovation contract, spend it, then approach furniture with whatever remains. The smarter sequence is to plan both budgets together from the start, set a floor for furniture quality you are unwilling to compromise on, and let that constraint shape how much carpentry you commission, not the other way around. ## Plan the Whole Room, Not Just the Renovation Renovation design costs what it costs partly because good space planning is genuinely skilled work. But the design only lives fully once the furniture is in. The homes that look and feel most considered are almost always the ones where those two budgets were planned as one, with clear priorities, honest material choices, and enough left over for pieces that last. Before your next site visit, spend an hour shortlining the furniture that matters most. **[Browse the full home furniture range](https://megafurniture.sg/collections/home-furniture)** with dimensions and material specs, and carry those numbers into the renovation conversation as a budget anchor, not an afterthought.
