BTO Renovation Cost in Singapore 2026: Full Breakdown by Flat Type

Last Updated: May 2026

A BTO renovation in Singapore in 2026 typically costs between SGD 30,000 and SGD 85,000 for a full custom renovation, depending on flat size and scope. A 3-room BTO ranges SGD 25,000 to SGD 45,000. A 4-room BTO ranges SGD 40,000 to SGD 65,000. A 5-room BTO ranges SGD 50,000 to SGD 85,000. These figures include carpentry, electrical works, tiling, design, and project management, but exclude loose furniture, appliances, and the 10 to 15 percent contingency buffer most homeowners need.

Move-in packages from established firms start considerably lower. Dreamakers’ BTO Move-In Package starts from SGD 6,888 for a 2-room BTO and goes up to SGD 8,888 for a 5-room BTO, covering kitchen carpentry, quartz worktop, full-flat painting, plumbing fixtures, design consultation, and a 5-year warranty. The right choice depends on your scope, timeline, and how much customisation you actually need.

This guide breaks down where every dollar goes, what drives costs up or down, and the hidden expenses most BTO owners only discover after signing — plus when a move-in package makes more sense than a full custom renovation.

1. Cost summary by flat type

The single biggest cost driver is flat size. More square footage means more flooring, more lighting, more carpentry, and more labour hours. The ranges below reflect 2026 Singapore market conditions across multiple HDB-registered renovation contractors and interior design firms.

3-room BTO (around 65 sqm): SGD 25,000 to SGD 45,000

A 3-room BTO has the smallest renovation scope. With one bedroom, one bathroom, a smaller kitchen, and a compact living area, total works fit comfortably under SGD 45,000 for mid-range builds. Lean BTO renovations focused on essential carpentry and a simple aesthetic can come in under SGD 30,000.

4-room BTO (around 90 to 100 sqm): SGD 40,000 to SGD 65,000

The 4-room BTO is the most common renovation project in Singapore. The wider range reflects greater design flexibility. Some owners prioritise storage and built-ins, pushing toward the upper end. Others adopt a minimalist approach with less custom carpentry, landing closer to SGD 40,000.

5-room BTO (around 110 sqm): SGD 50,000 to SGD 85,000

5-room BTOs cost more due to additional flooring area, an extra bedroom, and typically two bathrooms requiring tiling. Owners who pursue premium finishes or extensive smart home integration can exceed SGD 85,000, though most stay within the range.

Executive flats (around 130 sqm and larger): SGD 70,000 to SGD 110,000

Executive flats are the largest HDB type and follow the same per-square-foot logic. Most well-executed renovations land between SGD 70,000 and SGD 110,000.

A useful rough benchmark for any HDB flat: SGD 400 to SGD 700 per square metre for a complete renovation including design and carpentry. Below SGD 400 per square metre usually means a scope gap. Above SGD 700 per square metre typically signals premium finishes or extensive custom work.

2. Full custom renovation vs BTO move-in package

Not every BTO owner needs a full SGD 50,000 renovation. If your priorities are simple — get into the flat, have a working kitchen, clean walls, functional bathrooms — a move-in package handles all of that for a fraction of full renovation cost.

The choice comes down to scope.

When a move-in package fits

A move-in package suits BTO owners who:

• Want to move in within 4 to 8 weeks of key collection
• Are happy with the developer-supplied flooring, doors, and bathroom tiles
• Need essential kitchen carpentry, painting, and plumbing fixtures done well
• Plan to add custom carpentry, feature walls, or smart home features later when budget allows
• Want a fixed price with no scope creep

When a full custom renovation fits

A full custom renovation suits BTO owners who:

• Want all carpentry custom-built including wardrobes, TV consoles, study desks
• Need significant layout changes (open-concept kitchens, study rooms, walk-in wardrobes)
• Are committing to a specific design direction (Japandi, modern industrial, minimalist)
• Want false ceilings, feature walls, premium tiles, or smart home pre-wiring
• Plan to live in the flat for 10+ years

The Dreamakers BTO Move-In Package

For homeowners in the first category, Dreamakers offers a transparent BTO Move-In Package starting from SGD 6,888 for a 2-room BTO. Pricing scales with flat size: SGD 7,288 for 3-room, SGD 7,888 for 4-room, and SGD 8,888 for 5-room.

What’s included:

Kitchen carpentry: Top and bottom kitchen cabinets in solid plywood with laminate finish (20 feet total run), double-tier stainless steel dish rack, frosted glass door panel with hydraulic system, 4-drawer chest with cutlery tray, hob and hood installation labour.

Quartz worktop: 10 feet of quartz worktop including backsplash and profile finishing.

Masonry: 50mm kitchen cabinet base with tile finishing.

Plumbing: Outlet pipes for kitchen sink and washing machine, installation of kitchen sink and tap, bathroom accessories for master and common bathrooms, instant water heater installation for both bathrooms.

Painting: Nippon Emulsion paint for entire flat (walls and ceiling, up to 5 colours), Nippon Enamel paint for doors, frames, and sewage pipes.

Professional services: Design consultation, perspective drawings on all carpentry works, space planning and layout proposal, material and colour scheme proposal, 3D visual presentation, project management and site supervision, and a 5-year workmanship warranty with guaranteed after-sales service.

Site protection and cleanup: Corrugated cardboard floor protection throughout the unit, chemical wash and general cleaning on completion.

The package excludes flooring replacement, bathroom tile work (restricted under HDB 3-year rule anyway), wardrobes and built-in furniture beyond the kitchen, feature walls, false ceilings, and any electrical works beyond the included plumbing fixtures. Homeowners typically add these incrementally as needs and budget evolve.

Why a 5-year warranty matters

Most renovation contractors in Singapore offer 1-year workmanship warranty as standard. Better firms offer 2 to 3 years. A 5-year warranty signals confidence in materials and workmanship — and protects you against the most common BTO renovation issues like cabinet alignment, hardware failure, paint peeling, and grout cracking, which typically surface in years 2 to 4.

3. Where the money actually goes

Understanding the cost breakdown helps you compare quotations and decide where to spend or save. For a typical 4-room BTO renovation at SGD 50,000:

Carpentry: 35 to 45 percent (SGD 17,500 to SGD 22,500)

Carpentry is consistently the largest cost. This covers kitchen cabinets, bedroom wardrobes, TV consoles, shoe cabinets, and any built-in storage. Pricing depends on material grade (plywood with laminate is the Singapore standard) and complexity. Soft-close hinges, premium hardware, and full-height units cost more.

Tiling and flooring: 12 to 18 percent (SGD 6,000 to SGD 9,000)

Includes bathroom tiling (typically two bathrooms in a 4-room BTO), kitchen splashback, and main living area flooring. Vinyl flooring is the cost-effective default at SGD 4 to SGD 8 per square foot installed. Porcelain tiles run SGD 6 to SGD 12. Engineered wood costs SGD 10 to SGD 18.

Electrical works: 8 to 12 percent (SGD 4,000 to SGD 6,000)

Power points, lighting circuits, data points, and any rewiring. A 4-room BTO typically needs 35 to 50 power points across all rooms. Each additional point costs SGD 60 to SGD 120 depending on location and complexity.

Plumbing: 4 to 6 percent (SGD 2,000 to SGD 3,000)

First-fix and second-fix plumbing including any point relocations within wet areas. BTO plumbing scope is limited compared to resale flats because the existing infrastructure is new.

Painting: 4 to 6 percent (SGD 2,000 to SGD 3,000)

Full flat repaint with two-coat application. Includes wall preparation, primer, and finish coats. Premium paint brands and feature walls add to this figure.

Design fees and project management: 8 to 15 percent (SGD 4,000 to SGD 7,500)

Interior designer fees cover space planning, 3D renderings, material curation, permit submissions, and on-site coordination. Some firms bundle this into the package, others charge separately. At Dreamakers, design fees are bundled into the total renovation cost with no separate charge.

False ceilings, feature walls, and other works: 5 to 10 percent (SGD 2,500 to SGD 5,000)

Optional but common additions. False ceilings cost SGD 6 to SGD 15 per square foot. Feature walls range from SGD 600 for painted accents to SGD 4,000 for fluted wood panelling.

Permits, disposal, and miscellaneous: 2 to 4 percent (SGD 1,000 to SGD 2,000)

Includes lift padding, common corridor protection, debris haulage to NEA-approved sites, neighbour notification letters, and renovation permit submission costs. HDB itself does not charge a homeowner-facing permit fee. The cost is administrative work handled by the contractor.

4. What drives BTO renovation costs up

Five factors account for most cost variation between similar BTO renovations:

Carpentry volume and material grade

The biggest single variable. Full-height carpentry from floor to ceiling costs 30 to 50 percent more than standard 2.1m height units but doubles the storage capacity. Solid plywood backing costs more than chipboard but lasts longer in Singapore’s humidity. Premium hardware (Blum, Hettich) costs SGD 200 to SGD 600 per cabinet versus generic at SGD 50 to SGD 150.

Feature walls and design accents

A single fluted wood panel feature wall can add SGD 2,500 to SGD 4,000. Stone or marble veneer panels reach SGD 8,000. Designer wallpaper installation runs SGD 1,500 to SGD 3,500 per room. These are visual statements rather than functional necessities.

Smart home integration

Pre-wired smart home setups at the renovation stage cost SGD 3,000 to SGD 15,000 depending on coverage. Basic smart lighting and motorised curtains start at SGD 3,000. Full integration with climate control, security, voice control, and pre-wired Cat6 networking across a 4-room flat reaches SGD 10,000 to SGD 15,000.

False ceilings and lighting design

Throughout-flat false ceiling with cove lighting integration runs SGD 4,500 to SGD 8,500 for a 4-room. Skip it and the savings drop straight to the bottom line. Most BTO ceilings at 2.7m can support false ceilings without feeling oppressive.

Premium tiles, countertops, and finishes

Standard porcelain tiles at SGD 6 to SGD 12 per square foot versus premium imported at SGD 15 to SGD 25 doubles the tile budget. Quartz countertops at SGD 80 to SGD 150 per linear foot versus sintered stone at SGD 180 to SGD 350 makes a similar difference. These choices compound across the flat.

5. What you can skip safely

Not every BTO renovation needs every element. The following are common items where skipping makes minimal practical difference:

Feature walls

Skip in less-used rooms. A bedroom feature wall serves no functional purpose. Concentrate any feature work in the living room where it has visual return.

Throughout-flat false ceilings

Limit false ceilings to the living room and kitchen, where lighting integration matters most. Bedroom false ceilings rarely justify the SGD 1,000 to SGD 2,000 each they cost.

Custom carpentry in every room

Modular wardrobes from major retailers cost 40 to 60 percent less than custom built-ins and work well for bedrooms with standard wall sizes. Custom carpentry is most valuable in the kitchen, living room TV console, and any awkward niche space.

Premium tiles in low-traffic areas

Bedroom flooring sees light use. Mid-tier porcelain or quality vinyl performs identically to premium tiles in these areas. Save the premium tiles for living areas and kitchen splashbacks.

Imported designer fixtures

A reliable Singapore-brand tap performs identically to an imported European tap in normal use. Reserve premium fixtures for visible focal points like the kitchen sink area.

6. Sample budgets

Before walking through three sample full-renovation budgets, it’s worth noting that not every BTO owner needs a renovation at this scale. A move-in package at SGD 6,888 to SGD 8,888 covers essential carpentry, painting, plumbing fixtures, and a quartz worktop — enough to move in comfortably and add features over time. The budgets below are for owners pursuing a fully designed, custom-fit renovation from day one.

Budget A: SGD 45,000 — Functional, restrained

A workable BTO renovation that delivers a complete, livable home without premium features:

• Carpentry (kitchen + 2 wardrobes + TV console + shoe cabinet): SGD 18,000
• Vinyl flooring throughout: SGD 5,500
• Bathroom tiling (overlay method, two bathrooms): SGD 6,500
• Electrical (40 power points, basic lighting): SGD 4,000
• Plumbing: SGD 2,000
• Painting: SGD 2,000
• Design and project management: SGD 4,000
• False ceiling (living + kitchen only): SGD 2,000
• Miscellaneous: SGD 1,000

Budget B: SGD 65,000 — Balanced, mid-market

The most common Dreamakers BTO project budget, balancing aesthetic ambition with restraint:

• Carpentry (full-height kitchen + 3 wardrobes + TV feature + shoe cabinet + study desk): SGD 26,000
• Engineered wood flooring in bedrooms, porcelain in living areas: SGD 8,500
• Bathroom tiling (overlay, two bathrooms with upgraded fixtures): SGD 8,500
• Electrical (50 power points, full lighting design): SGD 5,500
• Plumbing: SGD 2,500
• Painting (with one feature wall): SGD 2,800
• Design and project management: SGD 6,000
• Full false ceiling with cove lighting: SGD 4,500
• Miscellaneous: SGD 1,000

Budget C: SGD 85,000 — Premium, design-forward

For owners pursuing a fully designed, magazine-quality home:

• Premium carpentry with imported hardware: SGD 32,000
• Porcelain tiles throughout with premium engineered wood in bedrooms: SGD 12,500
• Premium bathroom tiling with rain shower and feature wall: SGD 11,500
• Electrical (full smart home pre-wiring, 60+ points): SGD 8,000
• Plumbing (with bidet, water filter, premium fixtures): SGD 3,500
• Painting (premium brand, multiple feature walls): SGD 3,500
• Design and project management (extended scope): SGD 8,000
• Full false ceiling with smart lighting integration: SGD 5,500
• Smart home base package: SGD 5,000
• Miscellaneous: SGD 1,500

7. Hidden costs first-time BTO owners miss

The line items above cover the renovation itself. Most first-time BTO owners forget the following:

GST at 9 percent

If your quotation excludes GST, a SGD 50,000 renovation becomes SGD 54,500. Always confirm whether quotes include or exclude GST. CaseTrust-accredited firms typically state this clearly. Some smaller contractors do not.

Contingency buffer of 10 to 15 percent

Variations during renovation are nearly universal. Adding a feature, changing a finish, or addressing a site issue typically costs SGD 500 to SGD 3,000 each time. A SGD 5,000 to SGD 7,500 contingency on a SGD 50,000 renovation absorbs these without budget panic.

Loose furniture and appliances

Quotations cover built-in carpentry, not your sofa, dining table, beds, mattresses, fridge, washing machine, oven, or hob. Loose items typically add SGD 8,000 to SGD 25,000 to your total move-in cost.

Air conditioning installation

Most renovation contractors exclude aircon. A typical 4-room BTO aircon installation (one system with 3 fan-coil units) costs SGD 3,500 to SGD 6,500 including units and installation by a separate aircon specialist.

Curtains, blinds, and window coverings

Window dressings for a full 4-room BTO range SGD 1,500 to SGD 4,500 depending on style and motorisation.

Lighting fixtures

Decorative lights, pendants, and feature lighting are often excluded from electrical works. Budget SGD 1,000 to SGD 3,000 separately.

Defect rectification period costs

Most issues that emerge in the first 1 to 3 months after handover should be covered by your renovation warranty. But unforeseen items like ceiling repaints after aircon installation or minor adjustments occasionally fall outside warranty scope.

Moving and storage

If you are timing the renovation against the end of a current lease, factor in moving costs (SGD 300 to SGD 1,500) and any temporary storage needs.

8. GST, permits, and other regulatory costs

Singapore’s GST has been 9 percent since 1 January 2024. Every reputable renovation quotation must state clearly whether the price includes or excludes GST.

HDB does not charge homeowners a direct fee for the renovation permit. The administrative work is handled by your HDB-registered renovation contractor. However, your contractor must hold a valid HDB Registered Contractor licence, which you can verify on the HDB Directory of Renovation Contractors at hdb.gov.sg.

For BTO flats, two regulatory points often catch first-time owners off-guard:

The 3-year wet area hacking restriction: BTO flats have a 3-year restriction on hacking bathroom and toilet wall and floor tiles. This protects HDB’s waterproofing warranty. The compliant alternative is tile overlay, where new tiles are installed over existing surfaces without hacking. Most BTO bathroom renovations use this method.

Approved renovation hours: General works are permitted 9am to 6pm on weekdays and Saturdays. Noisy works including hacking, drilling, and tile cutting are restricted to 9am to 5pm on weekdays only. No renovation is permitted on Sundays or public holidays.

Permit completion deadline: Approved BTO renovations must be completed within 3 months of permit issuance. Resale flats have a 1-month deadline.

9. Financing your BTO renovation

Three main financing routes for Singapore BTO renovations:

Bank renovation loan

Local banks (DBS, OCBC, UOB) offer renovation loans capped at SGD 30,000 or 6 times your monthly income, whichever is lower. Interest rates currently range 3 to 6 percent per annum. Tenure is typically 1 to 5 years. Renovation loans must be used for renovation only and cannot fund furniture or appliances.

Personal loan

For renovations exceeding SGD 30,000, many homeowners combine a renovation loan with a personal loan for the balance. Personal loan rates are higher (typically 6 to 10 percent) but the funds can be used flexibly.

Cash savings

Most renovation deposits and progress payments require cash flow. Even with a renovation loan, you will need SGD 5,000 to SGD 15,000 in cash for the initial deposit and early-stage payments.

CPF cannot be used for renovation. CPF funds may only fund the home purchase itself (downpayment, monthly mortgage). Any attempt to use CPF for renovation is not permitted.

A typical payment schedule for a Singapore BTO renovation:

• 20 percent deposit on contract signing
• 30 percent on commencement of hacking (or first material delivery for BTOs without hacking)
• 20 percent on commencement of carpentry installation
• 20 percent on substantial completion
• 10 percent retained for 1 to 3 months until defect rectification is complete

The 10 percent retention is your protection. Reputable firms accept it as standard practice. Firms that resist retention should be considered carefully.

10. How to keep your renovation within budget

Five practical disciplines that prevent the most common cost overruns:

Lock the scope before signing

Every item should be in writing before you sign. Provisional sums should have unit-rate caps. Variations must be confirmed in writing with the cost stated upfront, not after the work is done.

Pre-decide all material selections during the design phase

The most expensive variations are mid-renovation material changes. Choose your tiles, laminates, paint colours, and hardware brands during the design phase, before construction begins.

Get 3 to 5 itemised quotations

Compare on scope detail rather than headline price. A SGD 45,000 quote that excludes electrical works is more expensive than a SGD 52,000 quote that includes them. Use the line-by-line breakdown to verify like-for-like comparisons.

Reserve 10 to 15 percent contingency

Budget your total spend as 85 to 90 percent of available funds. Treat the contingency as part of the project, not a buffer you can return to savings.

Resist mid-renovation upgrades

Once works begin, every change adds cost and time. The discipline of saying no to additions during weeks 4 to 10 of construction saves most homeowners SGD 3,000 to SGD 8,000 in unplanned spend.
