Kovan and the surrounding District 19 estates have long been favoured by families who want landed living without sacrificing connectivity. Mature tree-lined streets, established schools and quick access to Kovan MRT give these plots lasting appeal — and many older terrace, corner-terrace and semi-detached homes now offer genuine rebuild or major A&A potential.
If you are weighing a full tear-down against a move-in-ready brand-new home, the decision hinges on more than square footage. Zoning, plot ratio, setback rules, soil conditions and comparables all shape what is feasible and what it is worth. CK Yong works with owners and buyers on the ground in Kovan, connecting you with architects, builders and transaction data before you commit.

Rebuild vs A&A: Which Path Suits Your Plot?
Both routes can transform a tired property, but the right choice depends on the existing structure, your budget and how much design freedom you need. The figures below are example ranges for illustration only.
Factor
Rebuild
Additions & Alterations (A&A)
Definition
Demolish the existing house and construct a new one on the same plot.
Retain the main structural frame while altering or adding to the existing house.
Typical project duration
12–18 months (design to move-in)
4–8 months (depending on scale)
Construction cost (example)
$320–$450 psf of built-up area
$280–$400 psf of affected area
Design freedom
Full, subject to URA planning controls and site constraints.
Limited by the existing envelope, foundations and structural grid.
Suitability
Older homes, major layout changes or compromised foundations.
Newer homes needing extra rooms, a refreshed facade or modest extensions.
Planning triggers
Full URA and BCA approvals generally required.
May be exempt if works stay within permitted limits; otherwise approvals apply.
Always verify exact allowances with URA Development Control and a qualified architect before committing. Rules and exemption thresholds change. Source references: URA Development Control guidelines and BCA building regulations, verified as of Q4 2026.
Not every buyer wants to manage a build. A brand-new terrace, corner terrace, semi-D or detached home that has already obtained TOP or is near completion lets you inspect finishes, verify floor plans and move in faster.
What to Look For
Check TOP or completion status, the builder’s track record, final gross floor area, car-porch configuration and whether setbacks were complied with before you exercise.
How CK Yong Verifies Value
We pull recent transaction history and nearby comparables so you can see whether the asking price aligns with land PSF and finished-built-up values in the same estate.
Financing Notes
Under-construction purchases usually follow a progressive payment schedule; completed homes use a normal mortgage. Speak to your bank or financial institution for exact eligibility.

Planning & Regulations
Planning Rules You Need to Know Before You Rebuild
A successful rebuild starts with a clear understanding of what the plot can legally become. These summaries are based on current guidelines; always confirm the latest position with URA and your architect.
Plot Ratio / Gross Plot Ratio (GPR)
Landed housing zones are governed by the URA Master Plan, which sets the Gross Plot Ratio for each parcel. Rebuilds must stay within the allowable GPR and any site-specific planning parameters. Source: URA Master Plan 2019 and subsequent amendments, as of Q4 2026.
Storey Height Controls
Different landed zones permit different maximum storey heights — commonly 2-storey, 2.5-storey or 3-storey where applicable. The exact height is determined by the zone and any street-block controls. Source: URA Development Control Guidelines.
Setbacks, Road Buffers and Side/Rear Requirements
Front setbacks, side and rear setbacks, and road buffer distances vary by landed housing zone and road category. These dictate how much of the plot can be built on. Source: URA Development Control Guidelines.
Envelope Control / Street-Block Control
Some streets or blocks have envelope or street-block controls to maintain a uniform streetscape. These guidelines limit overall building form, roof shape and facade treatments. Source: URA Development Control Guidelines.
Landed Housing Framework
Singapore citizens can purchase landed residential property. Singapore Permanent Residents may purchase strata landed housing in approved condominium developments. Foreigners are generally restricted from buying landed housing. Source: Singapore Land Authority (SLA) and URA.
URA Approval Workflow
A typical workflow includes Outline Plan / Provisional Permission, Development Control clearance, Building Plan approval through CORENET, and finally TOP or CSC before occupation. Timeline varies by project complexity and agency workload. Source: URA and BCA, Q4 2026.
Disclaimer: Planning rules change. Always confirm the latest requirements with URA, BCA, your qualified architect and your lawyer before purchase or commencement of works.

Do I need URA approval to rebuild my landed house?
Yes. A full rebuild generally requires planning and building plan approvals from URA and BCA before demolition or construction begins. Source: URA / BCA, Q4 2026.
Can I rebuild a landed property I just bought?
Ownership alone does not guarantee an immediate rebuild. You still need URA and BCA approvals, and must comply with lease/tenure terms and any strata or estate restrictions.
What is the difference between A&A and reconstruction?
Additions & Alterations (A&A) retain the existing structural frame. Reconstruction is effectively a rebuild: the existing house is demolished and a new one is erected.
How long does a typical landed rebuild take in Kovan?
A typical rebuild in Kovan takes roughly 12–18 months from design to move-in, depending on approval timelines, contractor selection and site conditions.
Can I use CPF to finance a rebuild?
CPF savings are generally for property purchase rather than construction or rebuild costs. Check the latest CPF Board and bank guidelines for your situation. Source: CPF Board.
Are there ABSD implications when buying a second property for rebuild?
Additional Buyer’s Stamp Duty may apply based on your residency status and property count. Refer to IRAS prevailing ABSD rates as of Q4 2026 and consult a tax professional. Source: IRAS.
