Landed House Renovation in Singapore

Your Legacy Home, Reimagined

A Guide to Landed House Renovation in Singapore

Owning a landed property in Singapore is a milestone, but turning that structure into a "forever home" is a journey of its own. Unlike a condo, a landed renovation isn't just about choosing tiles or paint—it’s about architectural vision, structural integrity, and creating a lifestyle that spans from your garden gate to your rooftop terrace.

​

At Cosmos Decor, we don't just "renovate"; we transform estates. Whether you’ve just collected the keys to a vintage terrace or are looking to modernize a family bungalow, here is everything you need to know about doing it right.

What Does a Landed Renovation Actually Involve?

Renovating a landed house is a different beast compared to an apartment. It’s not just about new tiles; it’s about structural integrity, maximizing natural light across multiple floors, and ensuring your outdoor space flows perfectly into your indoor living area.

​

Our team specializes in:

• A&A (Additions & Alterations): Adding that extra room or extending your living area to fit a growing family.

• Complete Spatial Planning: Making sure every square foot of your multi-storey home is functional and beautiful.

• Facade Modernization: Giving your home a fresh, contemporary look that stands out in the neighborhood.

Navigating Landed Renovation Rules & Regulations

Renovating a landed home isn’t just about aesthetics; it’s about compliance. In Singapore, failing to follow URA and BCA guidelines can lead to heavy fines or a "forced teardown" order. At Cosmos Decor, we handle the red tape for you.

Here are the critical areas you must pay attention to before starting your project:

​

1. The "50% Rule": A&A vs. Reconstruction

The scope of your renovation determines which permits you need.

• Additions & Alterations (A&A): If your renovation is minor and you retain more than 50% of the existing structure (including walls, floor slabs, and columns) and do not increase the Gross Floor Area (GFA) by more than 50%, it qualifies as A&A. This is generally faster and cheaper to approve.

• Reconstruction: If you replace more than 50% of the structure or add a new storey, it is legally classified as "Reconstruction." This requires stricter compliance, including the mandatory installation of a Household Shelter (Bomb Shelter).

2. Envelope Control Guidelines

Since 2015, URA has used an "Envelope Control" system to manage the height and volume of landed houses.

• Height Limits: For a 2-storey zone, the maximum building height is 12 meters. For a 3-storey zone, it is 15.5 meters.

• Mezzanines & Attics: These must fit within the allowable 3D "envelope" of your property. If your attic protrudes beyond the envelope, your plans will be rejected.

3. Setback Requirements (Boundary Rules)

You cannot build right up to your neighbor’s fence. URA mandates specific "setbacks"—the distance between your house and the boundary line:

• Front Setback: Usually 7.5m from the road (varies by road category).

• Side & Rear Setbacks: Typically 2m for most residential landed plots.

• Buffer Zones: These ensure privacy, ventilation, and fire safety between you and your neighbors.

4. Engaging a Qualified Person (QP)

For any structural work, you cannot simply hire a contractor. You must legally appoint a Qualified Person (QP)—either a Registered Architect or a Professional Engineer (PE).

• The QP is responsible for submitting your building plans via the CORENET system.

• At Cosmos Decor, we work with experienced QPs to ensure all architectural and structural drawings are cleared by BCA before the first hammer swings.

5. Neighbor Relations & Pre-Con Surveys

Being a "Good Neighbor" is part of the regulatory spirit in Singapore.

• Pre-Construction Survey: Before starting heavy works (like piling or hacking), a professional survey should be done on your neighbors' houses to document existing cracks. This protects you from false damage claims later.

• Working Hours: General renovation works are usually limited to 9:00 AM – 6:00 PM on weekdays. No noisy works are allowed on Sundays or Public Holidays.
