A landed owner in Singapore who starts talking about work on the house is doing exactly one of three things, and the three are not interchangeable: a renovation (cosmetic, no URA submission, funded in cash), an addition-and-alteration or A&A (structural, capped at 50% of the existing approved building, needs a Qualified Person to lodge it with URA), or a full rebuild (the existing house is torn down and a new one erected on the same land, on a construction loan, 18 months to three years, with a fresh set of approvals from URA, BCA and half a dozen other agencies). Which one you are doing is not a matter of budget alone. It is set by where you sit in the life of the property: about to move in and improve it (the BUYER), about to sell and wanting the highest offer (the SELLER), or committed to the land for decades and past the point where patching the old structure makes sense (the HOLDER).

The mechanics: three different projects, three different rulebooks

Renovation is anything that does not touch approved structure or approved floor area — new kitchen, new bathrooms, repainting, re-tiling, swapping non-structural partitions. It needs no URA lodgment and no Qualified Person. An addition-and-alteration crosses into URA's territory the moment it adds gross floor area, replaces external walls, or changes structure — but stays an A&A, not a rebuild, only while it stays under three linked 50% ceilings.

• An A&A must add no more than 50% to the existing approved gross floor area
• It must replace no more than 50% of the existing approved external walls
• It must change structure (new columns, beams, rebuilt floor slabs) on no more than 50% of the existing floor area
• Replacing the entire roof is allowed without counting against these limits, as long as it adds no storey
• Cross any one of the three and URA treats the whole proposal as reconstruction — a new erection, on the rebuild rulebook, not the A&A one

A proposal is reconstruction, not A&A, the moment it adds a storey or changes the housing form — a semi-detached becoming a bungalow, for instance — regardless of how small the added floor area is.

A Qualified Person — a registered architect or professional engineer — must lodge the A&A with URA: a proposal plan, a sketch plan, and a declaration of compliance. The lodgment authorisation runs two years from the acknowledgement letter, extendable twice before you have to start over.

A full rebuild sits under URA's Envelope Control: landed housing is capped at two storeys (12 m) or three storeys (15.5 m), whichever the Master Plan sets for that estate, inside a three-dimensional envelope built from setbacks and height. An attic can sit inside that envelope; a roof terrace on an attic has to stay at least 3 m below the top of it.

Where the existing house already sits outside the current envelope — built under older rules — any further A&A cannot add to its bulk, and URA assesses the application on its own facts rather than by a fixed formula. Retained non-conforming structure needs a Professional Engineer's certification that it is structurally sound.

Eligibility: who is allowed to hold the land at all

Before any of the three questions above matter, one gate sits in front of all of them: can you even own the landed house you're proposing to renovate, extend, or knock down? Landed housing in Singapore is restricted under the Residential Property Act. A Singapore Citizen owns it as of right. Everyone else needs the state's permission first — and the permission is not a formality.

• Singapore Citizen: no approval needed, no cap on land area
• Permanent Resident: needs Land Dealings Approval Unit (LDAU) approval — in practice this asks for at least five years as a PR plus an exceptional economic contribution to Singapore, assessed on Singapore-assessable income and investment; approval is discretionary and rarely granted
• FTA national (US, Switzerland, Liechtenstein, Norway, Iceland) who is not also a PR of five years: FTA parity is a stamp-duty rule only — it does not touch the Residential Property Act, so an FTA national still needs the same LDAU approval as any other foreigner
• Approved foreign owner (rare): capped at 1,800 sq m of land, for own occupation only, never for rental; processing runs about 30 working days once every document is in
• Entity or trust holding landed housing: separately restricted, and outside the scope of this page

If probate or a will passes a landed house to a foreign beneficiary who has no LDAU approval, the Residential Property Act does not let the transfer stand indefinitely: the executor or administrator is bound to sell the house to a citizen or an approved purchaser within five years of the grant.

A strata-titled landed house — a strata terrace or strata semi-detached under a Management Corporation — changes this whole page's premise in one respect worth flagging before eligibility: even a Singapore Citizen owner cannot unilaterally demolish and rebuild. The land is common property or a shared strata title, so a full rebuild only happens through the collective-sale (en bloc) mechanism, needing a majority of owners by count and by share value — not one owner's decision. An A&A on a strata landed unit still needs the Management Corporation's written consent before URA or BCA will accept the submission at all, and Joya Architects reports that consent step, not URA's or BCA's own processing, as the single biggest scheduling risk in the project.

Citizenship status and what it changes downstream

Once you clear the eligibility gate, citizenship status keeps mattering — at every tax and financing step below, not just at the front door. Four profiles run through this page differently: Singapore Citizen, Permanent Resident, foreigner (non-FTA), and FTA national. The FTA nationals — United States, Switzerland, Liechtenstein, Norway, Iceland — are taxed as Singapore Citizens for Additional Buyer's Stamp Duty, but that parity stops at the stamp duty line. It does not extend to the Residential Property Act eligibility gate above, and it does not extend to LDAU approval.

A US citizen who also holds Singapore PR status is charged ABSD at the Singapore Citizen rate under the FTA — but a US green card holder who is not a US national does not qualify at all; the remission follows nationality, not residence or a US tax filing status.

Taxes: what the state takes at each gate

Buyer's Stamp Duty is charged on every purchase, whatever your citizenship, on a progressive schedule: 1% on the first $180,000, 2% on the next $180,000, 3% on the next $640,000, 4% on the next $500,000, 5% on the next $1,500,000, and 6% on anything above $3,000,000. On a $2,000,000 landed purchase that is $69,600.

Additional Buyer's Stamp Duty is the number that actually sorts buyers by citizenship. A Singapore Citizen pays 0% on a first residential property, 20% on a second, 30% on a third and beyond. A Permanent Resident pays 5% on a first, 30% on a second, 35% on a third and beyond. A foreigner (non-FTA) pays a flat 60% from the first property. An entity pays 65%. FTA nationals use the Singapore Citizen schedule, but only by filing a remission application through the myTax Portal — it is not applied automatically at the point of purchase.

Seller's Stamp Duty applies only if you sell within the holding period, and it does not care why you're selling — a rebuild you can no longer afford to finish is still a sale inside SSD if the clock hasn't run out. The current schedule: 16% in year 1, 12% in year 2, 8% in year 3, 4% in year 4, nothing after.

Property tax is annual, and it treats you differently the moment you stop occupying the house yourself. Owner-occupier rates start at 0% on the first $12,000 of Annual Value and climb in bands to 32% above $140,000. The moment the house is let out, or is a second home you don't occupy, it moves to the non-owner-occupier schedule — 12% on the first $30,000 of AV, up to 36% above $60,000 — which is materially heavier at every band.

A rebuild has its own property-tax mechanics worth knowing before you start: once the old house is demolished, IRAS assesses the bare land at 5% of its estimated freehold market value and taxes it at the flat 10% non-residential rate — not the residential owner-occupier bands you were used to. IRAS grants owner-occupier rates back on land under construction for a single owner-occupied house, for up to two years, provided the AV of the land parcel is below $108,625 and you don't hold owner-occupier status on any other property in that window; the finished house then has to be owner-occupied for at least a year from TOP or CSC.

Rental income is taxed as personal income at your marginal rate once you let the house out, after deducting mortgage interest and allowable expenses — the same treatment any other landlord in Singapore gets, and a genuine cash inflow you should weight against the carry cost of financing the property, covered below.

Borrowing: land loan, construction loan, then a home loan

A renovation is a cash job — CPF savings cannot be used for renovation, improvement or repair work on your property, full stop, no exceptions listed on CPF's own page. An A&A on an existing house is usually financed the same way, or through a renovation loan, and MSR — the Mortgage Servicing Ratio — never enters this page at all: MSR applies only to HDB flats and executive condominiums during their minimum occupation period, and landed housing is neither.

A full rebuild runs on a different instrument entirely: a land loan, then a construction loan, then conversion to an ordinary home loan. Banks typically cap a land loan at about 55% LTV against the bank's own valuation of the land — well under the 75% LTV available on a completed home — and CPF use is restricted until a completed house actually stands on the land. The construction loan then draws in stages against certified progress, with interest charged only on what has actually been disbursed; once the house reaches Temporary Occupation Permit, the facility converts to a standard home loan, with LTV of 75% measured against the bank's valuation of the finished house (land plus building), net of any land loan still outstanding.

The land loan and the construction loan are assessed together, and they sit inside the same Total Debt Servicing Ratio ceiling from day one — 55% of gross monthly income, stress-tested at MAS's 4% floor rate regardless of the rate your bank actually quotes you. On a $5,000,000 terrace plot at 55% LTV that's a $2,750,000 land loan needing roughly $2,250,000 of cash up front, before Buyer's Stamp Duty and any ABSD.

Rate structure through a rebuild typically moves in phases: floating during construction, since the loan balance and the draw schedule are both moving targets and a bank has little appetite to lock a fixed rate against a facility it hasn't fully disbursed yet, then a choice of floating or fixed once the loan converts to a standard housing loan after TOP, priced like any other home loan at that point.

Which of the three, by lifecycle: the buyer, the seller, the holder

This is the actual question the page title asks, and the answer runs backwards from what most people assume. You do not pick reno, A&A or rebuild by budget size — you pick it by where you sit in the property's life, and each phase has a different economic reason to prefer one over the other two.

Renovation serves the buyer. You've just bought the house — or you're buying it — and you're not yet trying to extract anything from it; you're trying to live in it. Cosmetic work, no URA lodgment, cash-funded, fast. It doesn't touch the eligibility gate above, doesn't reset any stamp-duty clock, and it's over in weeks rather than years. It also does the least for resale value: a full renovation over roughly $80,000 on a landed home is commonly reported as not recovered in a sale, because a buyer who dislikes your taste simply replaces it.

A&A serves the seller. If you're planning to sell within the next one to two years, an addition-and-alteration — adding a bedroom, extending the kitchen, adding an attic within the 50% GFA cap — is reported to lift resale value by roughly 10-20%, against major A&A project costs commonly quoted at $600,000-1,200,000 for a home over 2,000 sq ft. That is a real premium against a real cost, and it's the one improvement path short enough (6 to 24 months depending on scope and which guide you read) to actually land before a listing goes out.

Full rebuild serves the holder. If you intend to hold this land for decades — pass it to your children, or simply never sell — a rebuild is the only one of the three that resets the clock completely: new structure, current Envelope Control compliance, no inherited non-conforming bulk, and (per the valuation point below) a house that a bank and a future buyer will both price as new rather than as a depreciating 30-year-old structure sitting on the land. It also carries the longest horizon and the largest exposure of the three, which is why the decision below treats it differently from the other two.

Landed housing is the one product on this site where all three lifecycle phases apply to the same asset. A condo owner doesn't rebuild; an HDB owner doesn't either. Only a landed owner runs into reno, A&A and rebuild as three live options on the same piece of land, at three different points in the same ownership.

THE VOICE: is this a balance-sheet play or a cash-flow play

• Cash, own-use: no loan, you live in it — pure appreciation play, no carry, nothing coming in or going out on financing
• Cash, let-out: no loan, tenant pays rent — positive carry by construction, every dollar of rent is yours after upkeep
• Borrow, own-use: a loan, you live in it — negative carry by construction, most owner-occupiers are here and few say it out loud
• Borrow, let-out: a loan, tenant pays rent — the spread play, and the gap between what the tenant pays and what the bank charges is the whole game

Conveyancing

None of the three routes on this page — reno, A&A, rebuild — is itself a conveyance; you already own the land. Conveyancing enters only if the project is financed with a new or refinanced loan (the lawyer handles the mortgage and any discharge of an existing one), or at the far end, if the finished house is later sold. A caveat lodged against the title — by a bank, or in some cases by a private lender who has taken the property as security — costs $64.45 to lodge or extend and $49.15 to withdraw, and while it stands, the property cannot be sold without repaying the underlying loan in full. The solicitor's job through a rebuild is narrower than through a purchase: registering the construction facility, tracking each disbursement against the loan agreement, and handling the discharge and re-mortgage when the facility converts to a standard home loan at TOP.

Estate: what happens if the holder doesn't finish

A rebuild is a multi-year commitment against land you may intend to leave to your children rather than sell — which means the estate question here is not abstract. If the land is held in joint tenancy, it passes automatically and in full to the surviving owner on death, outside the will and outside probate entirely — the construction loan and the unfinished (or finished) house pass with it, debt included. If it is held as tenants-in-common, or solely, it goes through the estate: a Grant of Probate if there's a valid will naming an executor, or Letters of Administration if there isn't, filed within six months of death, taking roughly two to three months to process for a straightforward estate through the Family Justice Courts. [⚠ estate.probate.eligibility_2026_06_15: sources differ; awaiting a ruling]

If the beneficiary who inherits the half-built or finished landed house is a foreigner without LDAU approval, the Residential Property Act does not let that stand indefinitely: the executor or administrator is bound to sell the property to a citizen or an approved purchaser within five years of the grant of probate or letters of administration — one more reason the eligibility gate at the top of this page belongs in an estate plan, not just a purchase plan.

The B2B spoke

I don't do construction, architecture or quantity surveying, and I'm not pretending otherwise on this page. What I've done is lay out the eligibility gate, the tax schedule and the financing structure in one place so you walk into your first conversation with a QP or a contractor already knowing which of the three you're doing and roughly what it costs — I've done that lead-gen work for you and I want nothing for it. If you get to the point of actually needing a realty mandate on this property — before, during or after the rebuild — think of me.

The realtor economics

CEA sets no fixed or prescribed commission rate for any residential transaction, landed included — it's negotiable, and has to be agreed in writing in the Prescribed Estate Agency Agreement before the agent starts marketing the property. Market norm on a landed resale runs around 2%, occasionally up to 4% on a private condo-style listing; on a $3,000,000 terrace sale, each 1% of commission is $30,000, so a common 2% is $60,000 before GST. One agent can never represent and collect commission from both sides of the same transaction — that is a CEA offence, not just bad practice — and any co-broke split between a seller's agent and a buyer's agent comes out of that same commission, not on top of it. Where the incentive points: an agent is paid on the transaction closing, not on the decision being right for you — which is exactly why a rebuild-vs-sell decision, worked through the numbers above before an agent is ever in the room, protects you against being talked into a sale (or a listing) that suits the commission more than it suits your balance sheet.
