HDB BTO Interior Design Packages
BTO flats arrive in bare condition. These ranges are indicative 2026 guides covering full ID packages — layout design, carpentry, flooring, painting, plumbing and electrical. The written proposal should state the selected drawings, materials, trade scope, project management, exclusions and variation process after the floor plan and brief are reviewed.
Why the wide range? The lower end covers laminate finishes and standard fittings; the higher end includes quartz countertops, sintered-stone backsplash, upgraded sanitary ware and more carpentry. Tell us your priorities and FixMove will tailor the spec to your budget — not the other way around.
Resale HDB Interior Design Cost
A resale flat may add hacking, disposal, rewiring, plumbing changes, waterproofing and rectification. Price these inspected items separately instead of applying one blanket uplift.
Condo Interior Design Cost
Condo renovations add MCST approval fees, lift-padding deposits, restricted work hours and often taller ceilings that increase carpentry cost.
Interior Design Fee Breakdown
Not every homeowner needs a full package. Here is what each tier of interior design service typically costs on its own.
ID firm vs direct contractor An ID firm and a direct contractor may package design, coordination and construction differently. Compare drawings, revisions, selections, supervision, approvals, payment stages, variations, responsible trades and exclusions on the same scope.

| Price Transparency | Bundled — harder to compare line items | Itemised quote |
| Price Structure | May bundle design, coordination and construction | May separate construction and optional design support |
| Best For | Busy owners wanting turnkey service | Hands-on owners wanting cost control |
What Affects Interior Design Cost?
Flat Type & Size
A 5-room HDB needs more materials, more carpentry and more labour than a 3-room. Condo units with higher ceilings push carpentry costs further.
BTO vs Resale
Resale flats incur hacking, disposal, rewiring and waterproofing that BTO flats skip. This alone adds 20–40% to the budget.
Material Grade
Laminate vs quartz countertops, vinyl vs marble flooring, standard vs premium sanitary ware — each tier step multiplies cost significantly.
Carpentry Volume
Built-in wardrobes, shoe cabinets, TV consoles and kitchen cabinets are the single largest cost driver in most Singapore renovations.
Wet-Area Scope
Full bathroom or kitchen overhaul (hacking, waterproofing, re-tiling, new fixtures) costs far more than cosmetic updates like repainting or new hardware.
Design Complexity
Feature walls, concealed lighting, curved carpentry and custom joinery all require more skilled labour and precise coordination.
Common Add-On Costs
Items often quoted separately from the base ID package.

Frequently Asked Questions
How much does interior design cost for a 4-room HDB BTO in 2026?
The S$40,000-S$62,000 band on this page is a planning range for a 4-room BTO design-and-renovation scope. Compare the drawings, carpentry, finishes, wet-area work, M&E coordination, project management, exclusions and revision terms in the written quote.
What is the difference between an ID firm and a direct contractor?
An interior-design firm may combine design development, drawings, selections and project coordination. A direct contractor may focus on the construction scope. Compare named deliverables, responsible parties, site supervision, approvals, payment stages, variations and exclusions rather than relying on a fixed markup assumption.
Does an interior design package include furniture and appliances?
Do not assume loose furniture, appliances or soft furnishings are included. Ask the quote to separate built-in carpentry, supplied fixtures, appliances, loose items, delivery, installation and exclusions.
How long does a full interior design project take?
The programme depends on design decisions, approvals, building rules, material lead times, site condition and construction scope. Request dated stages for design sign-off, submissions, procurement, site work, inspections and handover in the written proposal.
Can I request interior design consultation only?
Yes. The planning band on this page is S$50-S$250 for a one-off consultation and S$1,500-S$6,000 for a design-only scope. Confirm the session length, floor-plan review, drawings, selections, revisions and whether later project fees are separate.
Why can a resale-flat project cost more than a BTO project?
A resale unit may add demolition, disposal, rectification, waterproofing, rewiring, plumbing changes and making-good. The actual difference depends on the inspected condition and selected scope, so these items should be priced separately instead of applying one blanket percentage.
