Landed Property Renovation Cost Guide Singapore 2026
A complete landed property renovation in Singapore costs $150,000–$400,000 in 2026, or $400–$900 per square metre depending on finishes and structural work. Terrace houses typically run $200k–$350k, semi-detached $250k–$450k, and bungalows $350k–$600k+. Add 20–30% if you're doing major Addition & Alteration works requiring BCA approval. Landed renovations take 4–7 months including A&A permit processing. The bulk of your budget goes to structural work (25–35%), carpentry (20–30%), and M&E systems (15–20%).
Landed Property Renovation Cost Breakdown by Scope
Landed properties offer renovation freedom that HDB flats and condos can't match—you control the structure, façade, and layout. But that freedom comes with complexity and cost. Here's what you're paying for and why.
Basic Renovation vs Full Gut-and-Rebuild
A basic cosmetic renovation—new flooring, paint, kitchen cabinets, bathroom fittings—runs $80,000–$150,000 for a typical 2,000 sqft terrace house. You're keeping the existing layout and infrastructure.
A full renovation with layout changes—hacking walls, relocating wet areas, rewiring, new ceiling—pushes $200,000–$350,000. This is the most common scope for landed properties 15+ years old.
A gut-and-rebuild with major A&A—adding a storey, rear extension, new roof structure, full façade replacement—starts at $400,000 and easily exceeds $800,000 for large detached homes. You're essentially building new on the existing foundation.
Cost Per Square Metre by Finish Level
| Finish Level | Cost per sqm | What You Get |
|---|---|---|
| Builder-Grade | $400–$550 | Homogeneous tiles, laminate cabinets, basic sanitary ware, no special carpentry |
| Mid-Range | $550–$750 | Porcelain tiles, engineered wood, quartz tops, branded fixtures, custom carpentry |
| High-End | $750–$900 | Large-format tiles, solid timber, premium appliances, designer lighting, smart systems |
| Luxury | $900+ | Marble/natural stone, bespoke joinery, premium European fittings, full automation |
Trade-by-Trade Cost Allocation
For a typical $250,000 landed renovation (mid-range, 2,000 sqft, with moderate layout changes), expect this budget split:
- Structural & hacking work: $60,000–$75,000 (25–30%) — demolition, concrete work, new walls, waterproofing, beams
- Carpentry & built-ins: $50,000–$65,000 (20–26%) — kitchen cabinets, wardrobes, TV consoles, staircase if replacing
- M&E systems: $40,000–$50,000 (16–20%) — full rewiring, new consumer unit, lighting, ACs, plumbing, water heaters
- Flooring & tiling: $25,000–$35,000 (10–14%) — floor tiles, bathroom/kitchen wall tiles, skirting
- Painting & ceiling: $20,000–$25,000 (8–10%) — full repaint, ceiling repairs, new plaster ceiling if needed
- Bathroom & kitchen fittings: $18,000–$25,000 (7–10%) — sanitary ware, taps, sinks, hobs, hoods
- Doors, windows, grilles: $15,000–$20,000 (6–8%) — interior doors, main gate, window grilles, aluminium windows if replacing
Addition & Alteration (A&A) Works and BCA Permits
Unlike HDB or condo renovations, landed property structural changes require Building and Construction Authority (BCA) approval under the Building Control Act. This adds time and cost but opens design possibilities.
What Requires BCA A&A Approval
You need A&A submission and approval for:
- Structural alterations: removing or adding load-bearing walls, columns, beams
- Adding floor area: extensions, extra storeys, attic conversions, basement excavation
- Roof structure changes: raising roof height, adding skylights, changing pitch
- Façade modifications: altering external walls, moving main entrance, new balconies
- Major M&E changes: relocating main water tanks, upgrading electrical load beyond existing capacity
You do not need A&A approval for purely cosmetic work—painting, flooring, kitchen cabinets, bathroom fittings, minor partition walls—as long as you don't touch structure.
A&A Cost and Timeline
BCA submission and approval takes 4–8 weeks if straightforward, longer if queries arise. Fees:
- Qualified Person (QP) fees: $8,000–$25,000 depending on scope—your structural engineer or architect who submits plans
- BCA plan submission fee: ~$200–$500 (nominal)
- Structural engineer site inspections: $2,000–$5,000 for periodic inspections during works
- Construction cost premium: Actual structural work (new beams, columns, slabs) adds 20–40% to base renovation cost
For example, if you're adding a 300 sqft rear extension, budget $60,000–$90,000 for the structural frame, slab, and roof alone, plus QP fees. Then add finishes on top.
Gross Floor Area (GFA) Limits
Check your property's allowable GFA under URA regulations before planning extensions. Most landed homes are capped at 1.4–1.6 times plot size. If you're already at maximum GFA, you can renovate but not expand. Your QP will verify this during design.
Landed Renovation Timeline: What to Expect
Landed renovations take longer than HDB or condo projects because of scale, complexity, and A&A approval requirements. Here's a realistic timeline for a full renovation with moderate structural work.
| Phase | Duration | Key Milestones |
|---|---|---|
| Design & Planning | 3–5 weeks | Site measurements, layout drawings, material selection, quotation finalisation |
| A&A Submission (if required) | 4–8 weeks | QP prepares plans, submits to BCA, responds to queries, obtains approval |
| Hacking & Demolition | 1–2 weeks | Strip old finishes, hack walls, expose structure |
| Structural Work | 3–6 weeks | New walls, beams, slabs, waterproofing, brick/blockwork |
| Rough M&E Installation | 2–3 weeks | Electrical conduits, water pipes, AC trunking, data cabling |
| Ceiling & Partition | 2–3 weeks | Plaster ceiling, internal partitions, bulkheads |
| Tiling & Flooring | 3–4 weeks | Floor tiles, bathroom/kitchen wall tiles, skirting |
| Carpentry Installation | 4–6 weeks | Kitchen cabinets, wardrobes, built-ins—often overlaps with other trades |
| Painting | 2–3 weeks | Walls, ceilings, touch-ups |
| Final Fittings & Commissioning | 2–3 weeks | Doors, sanitary ware, light fixtures, appliances, AC commissioning, cleaning |
| Total | 4–7 months | From design to handover, including A&A approval time |
Larger projects with major A&A (adding storeys, full façade work) can stretch to 9–12 months. Weather delays during external works and material lead times for custom items add buffer.
Cost-Saving Strategies Without Compromising Quality
Landed renovations are expensive, but you can control costs without sacrificing durability or aesthetics. Here's where to spend and where to save.
Retain What Works
If your existing structure, roof, and windows are sound, don't replace them just for aesthetics. Repainting the façade and upgrading window grilles costs $8,000–$15,000 versus $40,000+ for new aluminium windows and external walls.
Keep your staircase if it's structurally sound. Refinishing timber treads or re-tiling costs $3,000–$6,000; replacing the entire staircase runs $15,000–$35,000.
Standardise Finishes Across Rooms
Using the same floor tile throughout (except wet areas) reduces wastage and labour. Buying 200 sqm of one tile gets better pricing than five different tiles. Same applies to paint colours, door designs, and light fixtures.
Limit Wet Area Relocations
Moving a bathroom or kitchen away from existing plumbing stacks requires new underground pipes, waterproofing, and floor height adjustments. Cost: $8,000–$15,000 per wet area relocation. If your existing bathroom locations work, leave them.
Choose Direct Contractors Over Design Firms
Hiring a design-and-build firm or interior designer adds 20–40% markup on trade costs plus design fees. A direct contractor like Larry Contractors gives you transparent trade pricing—you pay our carpentry factory direct rates, not middleman margins. For a $250k project, that's $40,000–$80,000 in savings you can redirect to better materials or contingency.
Plan for Future Upgrades
Do all your hacking, structural work, and concealed M&E now—those are expensive to redo. But you can phase cosmetic upgrades: install builder-grade sanitary ware now, upgrade to designer pieces in two years. Finish the main living areas first, complete the attic or helper's room later. This spreads cost over time.
Common Landed Renovation Pitfalls and How to Avoid Them
Underestimating Contingency Budget
Landed properties hide surprises—rotted roof beams, termite damage, old asbestos roofing, cracked foundations. Set aside 10–15% contingency on top of your quoted price. For a $250k renovation, that's $25,000–$37,500 buffer. You'll likely use half of it.
Ignoring Drainage and External Works
Your internal renovation looks perfect, but if your driveway cracks, boundary wall leans, or drainage clogs, you've got ongoing problems. Budget $15,000–$30,000 for external repairs: driveway resurfacing, boundary wall repainting, gate automation, drain clearing, perimeter tiling. Many homeowners defer this and regret it.
Skipping Proper Waterproofing
Landed homes have more water ingress points—roof, external walls, balconies, planter boxes. If your contractor skips proper waterproofing membrane and only does slurry coat, you'll get leaks within 2–3 years. Insist on two-layer waterproofing (membrane + protection layer) for all wet areas, balconies, and flat roofs. Adds $3,000–$6,000 but prevents $20,000+ future repairs.
Overlooking Cooling and Ventilation
Landed homes are larger and multi-storey. Undersized or poorly zoned air-conditioning leaves your upper floors hot. Install proper ducted or multi-split systems with capacity planning—expect $18,000–$35,000 for a full-house AC system (4–6 zones). Don't rely on window units or single-split ACs for large spaces.
Not Coordinating with Neighbours
Hacking, concrete drilling, and lorry access affect your neighbours. Inform them before works start, coordinate noisy work during reasonable hours (9am–5pm weekdays), and arrange shared access if your lorries block their driveway. Good neighbour relations prevent complaints and work stoppages.
Frequently Asked Questions
Do I need an architect or engineer for landed property renovation?
Only if you're doing structural A&A works. For cosmetic or minor layout changes (non-structural partitions, kitchen, bathrooms), you don't need a Qualified Person. But if you're adding floor area, altering load-bearing elements, or changing the façade, you must engage a QP (architect or engineer) to submit plans to BCA. QP fees range $8,000–$25,000 depending on scope.
Can I live in my landed property during renovation?
Possible but uncomfortable for full renovations. If you're only renovating one floor or doing phased works, you can stay in an unaffected area. For whole-house renovations with hacking and M&E rewiring, expect no water/power for days at a time, heavy dust, and noise. Most homeowners move out for 3–5 months. Budget $3,000–$5,000/month for temporary rental if needed.
How much does it cost to add an extra storey to a terrace house?
Adding a storey to a typical 2-storey terrace house (20ft frontage) costs $180,000–$280,000 including structural works, new slab, roof, staircase extension, and basic finishes for the new level. This assumes you're within allowable GFA. Add $10,000–$20,000 for QP fees and BCA submission. Timeline: 6–9 months including approval.
What is the typical lifespan of a landed property renovation?
A quality renovation lasts 12–15 years before you need another major refresh. Structural work (walls, floors, roof) lasts 20+ years. Finishes age faster: paint (5–7 years), carpentry laminate (8–12 years), tiles (15–20 years), waterproofing (10–15 years). M&E components like wiring and pipes last 15–20 years, but fixtures and appliances need replacement every 8–12 years.
Are landed property renovation costs tax-deductible in Singapore?
No. Renovation costs for residential properties (HDB, condo, or landed) are not tax-deductible in Singapore. If you're renovating a landed property used for business (e.g., home office, childcare centre, tuition centre), you may claim renovation expenses as capital allowances under IRAS rules—consult your accountant. For pure residential use, renovation is considered capital expenditure with no tax relief.
Why Landed Renovations Require Specialist Contractors
Landed properties involve scope and complexity beyond typical HDB or condo jobs. You're coordinating structural trades, external façade work, multi-storey M&E systems, larger carpentry volumes, and BCA compliance. You need a contractor with:
- BCA builder licence (GB1 or GB2) for structural works
- In-house trades to avoid subcontractor coordination delays—especially carpentry, which is 25% of your budget
- Experience with A&A approvals and QP coordination
- Site management capability for 4–7 month timelines with multiple overlapping trades
- Transparent pricing so you understand where every dollar goes, not bundled "packages" that hide margins
