Is your terrace, semi-detached or bungalow showing its age: leaking roofs, cramped rooms, too few bedrooms, or no space for a home lift? A full house reconstruction in Singapore lets you keep your land and address and still end up with a home that feels new. Three E Building Construction Pte Ltd (3E Build) handles landed house rebuilds in Singapore from first sketch to handover through our Landed Property Design and Build service, with one team for design, authority submissions and construction.
This guide covers what URA counts as reconstruction and what counts as Additions & Alterations (A&A), how the approval process works, how long a rebuild usually takes, and what affects the cost of rebuilding a landed house in Singapore.
Reconstruction vs A&A: What’s the Difference?
The Urban Redevelopment Authority (URA) sorts landed house works into three categories. Which one your project falls into decides what you can build and which submissions you need.
- Additions & Alterations (A&A): the works stay within URA’s 50% limits. Added gross floor area (GFA) must not exceed 50% of the approved GFA. No more than 50% of the approved external walls can be removed and replaced (door and window replacement doesn’t count). Structural changes such as new columns, beams or rebuilt floor slabs must not exceed 50% of the existing building. You can replace the whole roof as long as this doesn’t add a storey.
- Reconstruction: any proposal that goes over the A&A criteria. Under URA guidelines, adding a storey or changing the housing form (for example, from semi-detached to detached) is always treated as reconstruction, even if the works stay under the 50% limits.
- New erection: under URA’s explanatory notes, demolishing the entire house counts as a new erection.
Smaller upgrades such as a new kitchen, an extended car porch or an attic are usually best handled under our A&A Works service. If you want a new layout, an extra storey or a modern façade, it is usually cleaner to rebuild. You can read more about adding a storey in our guide on how to add an extra storey to your 2-storey landed property.
House Types We Rebuild
Terrace House Rebuild
Intermediate and corner terraces are among the most common rebuild projects in Singapore. Because terrace houses share party walls with neighbours, they need careful structural planning and steps to protect the adjoining houses. One recent example is our modern inter-terrace house, which has a vertical timber-look façade, full-height architectural screens and glass balcony balustrades. Its total construction cost was S$1.4 million.
Semi-Detached Rebuild
A semi-detached rebuild gives you more room for features like double-volume living areas, a home lift and a rooftop terrace. Like a terrace, a semi-D shares one wall with the neighbour, so we plan the foundations and the junction with the adjoining house before demolition starts.
Bungalow (Detached House) Rebuild
A detached bungalow gives you the most design freedom, with room for a swimming pool, a basement or larger landscaped grounds. Bungalows in Good Class Bungalow Areas follow separate URA controls, so we check your site’s planning parameters early.
Step-by-Step Rebuild Process and Approvals
- Initial consultation: we look at your land size, the gross floor area you want, the number of storeys and bedrooms, and extras such as a pool or lift, then match these to your budget.
- Architectural design: concept designs that make the most of natural light, cross ventilation, privacy and practical layouts, all within URA’s landed housing and Envelope Control guidelines.
- Government approvals: submissions to URA (planning), BCA (building and structural plans) and, where relevant, PUB, SCDF and the utility agencies. Getting the plans approved before work starts keeps the project compliant.
- Demolition and site preparation: we protect neighbouring properties (especially for terraces and semi-Ds) and prepare the site.
- Construction: foundations, the reinforced concrete structure, brickwork, roofing, windows and doors, then mechanical and electrical installation.
- Finishes and handover: interior finishes, external works, testing and commissioning, and quality inspections before you move in.

How Long Does a Landed House Rebuild Take?
Timelines vary by project, but a typical landed house project in Singapore looks like this:
- Design: 2–3 months
- Authority approvals: 3–5 months
- Construction: 12–16 months
All in, plan for roughly 1.5 to 2 years from first design to moving in. How complex the project is and how long the authorities take to process submissions both affect the actual timeline. Remember to budget for somewhere to stay while the works are underway.
Cost of Rebuilding a Landed House in Singapore
Our landed house cost guide gives these published ranges:
- Reconstruction: typically S$250–S$450 psf, depending on the condition of the retained structure and how complex the rebuild is.
- New erection (2–3 storeys): typically S$300–S$500 psf. A terrace house typically needs a budget of about S$1.4M–S$1.8M.
- A&A works: from about S$150 psf for minor works, and S$200–S$400 psf for larger structural alterations.
Main cost factors include how much is demolished, structural upgrades, joining old and new structures, site and soil conditions, basements, swimming pools, home lifts, façade materials, finishes and smart home systems. Also budget for professional fees (typically 8–12% of the construction cost), regulatory and submission fees, temporary housing, and a 10–15% contingency.

Frequently Asked Questions
What is the difference between reconstruction and A&A for a landed house?
Under URA guidelines, works count as A&A only if added GFA, replaced external walls and structural changes each stay within 50% of the existing approved building, and no storey is added. Anything beyond that is reconstruction. Demolishing the whole house is a new erection.
Is adding a storey considered reconstruction?
Yes. URA treats any increase in storey height as reconstruction, even if the works stay under the 50% limits. The same applies to changing the housing form, for example from semi-detached to detached.
How much does it cost to rebuild a landed house in Singapore?
Our cost guide puts reconstruction at about S$250–S$450 psf and new erection at about S$300–S$500 psf. For a terrace house, a budget of about S$1.4M–S$1.8M is typical. Our recent modern inter-terrace rebuild cost S$1.4 million.
How long does a terrace house rebuild take?
Typically 2–3 months for design, 3–5 months for authority approvals and 12–16 months for construction. The actual time depends on how complex the project is.
Which approvals do I need to rebuild my house?
Landed house projects need approvals from URA and BCA, and may also involve PUB, SCDF and the utility agencies. As a Design & Build contractor, 3E Build coordinates these submissions for you.
Should I choose reconstruction or A&A?
Choose A&A if your house is structurally sound and you only need targeted upgrades. Choose reconstruction or a new erection if you want a new layout, an extra storey or a modern home that will last. We can assess your property and advise you.
