Landed property renovation in Singapore typically costs $80,000 to $600,000 or more, depending on whether you're doing a cosmetic refresh or a full addition and alteration (A&A). Unlike HDB flats, landed homes may need URA planning permission and BCA structural approval before work starts. This guide breaks down 2026 costs, approval timelines, and what terrace, semi-detached, and bungalow owners should budget for.

This guide is for informational purposes. Prices and regulations may change — always verify with HDB, BCA, or your interior designer.

How Much Does Landed Property Renovation Cost in Singapore (2026)?

Landed property renovation cost in Singapore varies more than any other housing type, because the scope can range from repainting a terrace house to rebuilding a bungalow from the ground up. Your final bill depends on land size, structural changes, and finishing quality.

As a general rule, budget more per square foot than you would for a condo or HDB flat. Landed homes have larger floor areas, exterior works like roofing and driveways, and often need a Qualified Person (QP) — a registered architect or engineer — to submit plans to the authorities.

The table below gives realistic 2026 ranges by renovation scope, based on quotes gathered from renovation firms on Renonation.sg.

Within each scope, your choice of materials moves the number a lot. A mid-range finish uses ceramic tiles, laminate flooring, and standard sanitary ware. A premium finish swaps in engineered timber, natural stone, and imported fittings, which can add 20-40% to your total budget for the same floor area.

Renovation Scope Cost Range (SGD) Typical Duration

Cosmetic refresh (painting, flooring, minor works) $30,000 – $80,000 3 – 6 weeks

Full interior renovation (no structural change) $100,000 – $250,000 3 – 5 months

Addition & Alteration (A&A) — extension or new storey $300,000 – $600,000+ 9 – 18 months

Rebuild (new landed house on existing plot) $800,000 – $1,500,000+ 18 – 24 months

Terrace vs Semi-Detached vs Bungalow: Cost Differences

Your property type shapes both your budget and your design freedom. Terrace houses share party walls with neighbours on both sides, which limits structural changes near the boundary. Semi-detached houses share just one wall, giving you more room for extensions. Bungalows stand alone, so you get full design freedom, but also face closer scrutiny from URA on setbacks and building height.

Land size drives the cost gap. A bungalow renovation covers far more floor area than a terrace house, so even at a similar cost per square foot, the total bill is much higher.

Corner terrace units sit closer to bungalow economics, since they have one exposed side wall and slightly more setback flexibility than an inner-terrace unit sandwiched between two neighbours. If you're eyeing a Good Class Bungalow (GCB) — the most tightly controlled landed category — expect longer URA review times and stricter plot ratio and greenery requirements than a standard bungalow plot.

Property Type Typical Land Size Renovation Cost Range Key Consideration

Terrace 1,400 – 2,000 sqft $80,000 – $300,000 Shared party walls limit structural changes

Semi-Detached 2,000 – 3,500 sqft $150,000 – $400,000 One shared wall gives more A&A flexibility

Bungalow 3,500 – 8,000+ sqft $250,000 – $600,000+ Full design freedom, higher URA scrutiny

URA & BCA Approval: What You Need Before You Renovate

Not every landed renovation needs government approval. Internal, non-structural work — painting, flooring, built-in wardrobes, or swapping kitchen cabinets — usually doesn't require URA or BCA sign-off.

Design: Weiken

You'll need approval once you touch Gross Floor Area (GFA) — the total floor area counted for planning purposes — or the building's structure or external envelope. This covers extensions, adding a storey, enclosing a balcony, or moving load-bearing walls.

For these works, you engage a Qualified Person (QP), typically an architect or professional engineer, who prepares and submits plans to URA for planning permission and to BCA for structural approval. Most straightforward A&A applications take 4-8 weeks for URA and a further 4-6 weeks for BCA, though these can often run in parallel.

Skipping this step is risky. URA can issue a stop-work order or demand you reinstate the property to its original state at your own cost if you renovate without approval.

Beyond GFA and structure, URA also checks your plans against plot ratio limits, building setback lines from your boundary, and site coverage — the percentage of your land that buildings can occupy. These vary by planning area, so ask your QP to confirm the specific controls for your address before finalising a design that extends your footprint.

Renovation Timeline for Landed Properties

A full A&A renovation for a landed home typically takes 9 to 18 months from design to handover. The timeline below breaks down each phase for a mid-sized extension project.

Phase Typical Duration

Design development & QP engagement 4 – 8 weeks

URA & BCA approval (can run in parallel) 4 – 8 weeks

Demolition & structural works 6 – 10 weeks

M&E (mechanical & electrical) and finishing 8 – 12 weeks

Final inspection & Certificate of Statutory Completion (CSC) 2 – 4 weeks

How to Save Money on Landed Property Renovation

Landed renovations are expensive, but a few decisions can meaningfully cut your budget without cutting corners on quality.

Design: Weiken

The biggest lever is scope discipline: decide upfront which rooms genuinely need structural change versus a cosmetic refresh, and resist adding new requests once construction starts.

Retain your existing structural footprint where possible — new foundations and structural steel are the most expensive line items.

Get at least 3 quotes from BCA-registered contractors before committing, since prices for the same scope can vary by 20-30%.

Phase your renovation across 2-3 stages if cash flow is tight, starting with structural and wet areas before cosmetic finishes.

Lock your design and finishes before construction starts — mid-project changes are the single biggest cause of budget overruns.

Ask your bank about renovation loan options; most landed homeowners fund renovations through a bank renovation loan or cash, since HDB loans don’t apply to private property.

Reuse existing plumbing and electrical risers where the layout allows, since relocating these is one of the costlier hidden line items in any renovation quote.

Choosing a Contractor for Landed Renovation

A&A projects need a contractor with real landed-property experience, not just HDB or condo renovation history. Structural works, drainage, and roofing require different expertise and different regulatory sign-offs.

Design: Weiken

Look for BCA registration, CaseTrust accreditation, and a portfolio of completed A&A or rebuild projects you can visit or call references for. Ask specifically how many landed projects they’ve delivered in the past two years, and whether they manage the QP submission themselves or coordinate with an external architect.

Get every quote itemised by trade — demolition, structural, M&E, and finishes — so you can compare like-for-like across firms instead of a single lump sum that hides where the money actually goes.

Frequently Asked Questions

How much does it cost to renovate a landed property in Singapore in 2026?

Landed property renovation in Singapore costs $30,000-$80,000 for a cosmetic refresh, $100,000-$250,000 for a full interior renovation, and $300,000-$600,000+ for an addition and alteration (A&A) project. Rebuilds can exceed $1,500,000.

Do I need URA approval to renovate my landed house?

You need URA planning permission only if your renovation changes your Gross Floor Area or the building’s structure or external envelope. Internal, non-structural work like painting or flooring generally doesn’t require approval.

Can I add a second storey to my terrace house?

In many cases yes, subject to URA planning controls on height, setbacks, and plot ratio for your specific area. A Qualified Person needs to assess feasibility and submit plans before you proceed.

How long does landed property renovation take?

A cosmetic refresh takes 3-6 weeks. A full A&A project, including URA and BCA approval, typically takes 9-18 months from design to handover.

What’s the difference between A&A and rebuilding?

Addition and Alteration (A&A) retains your existing structure and adds to or modifies it. Rebuilding demolishes the existing house and constructs a new one on the same plot, which costs significantly more and takes longer.

Do landed homeowners need a renovation loan?

Landed properties don’t qualify for HDB renovation loans. Most homeowners use a bank renovation loan, typically capped around $30,000-$50,000, or a combination of cash and a personal loan for larger A&A budgets.

What happens if I renovate without approval?

URA can issue a stop-work order and require you to reinstate the property to its approved state at your own cost. Unauthorised structural works can also affect your fire insurance and future resale.
