Introduction to Selective Demolition in Singapore
Selective demolition or hacking is becoming increasingly common in Singapore’s renovation and construction industry. Unlike full demolition, which involves tearing down an entire structure, selective demolition focuses only on removing specific parts of a building while preserving the rest.
In many renovation projects, especially in HDB flats, condominiums, and commercial spaces, homeowners and business owners want to upgrade or redesign their spaces without rebuilding everything from scratch. This is where selective demolition Singapore services play an important role.
Selective demolition allows contractors to carefully remove targeted elements such as walls, flooring, ceilings, or fixtures while ensuring surrounding structures remain intact. This makes it a more controlled, efficient, and cost-effective approach compared to full demolition.
This guide explains everything you need to know about selective demolition, including its uses, process, cost factors, safety requirements, and how to choose the right contractor in Singapore.
What Are Selective Demolition Works?
Selective demolition refers to the careful removal of specific parts of a structure without affecting the entire building.
It involves dismantling:
- Non-structural walls
- Flooring materials
- Ceiling structures
- Built-in fittings
- Selected concrete sections
- Old fixtures and finishes
The goal is to preserve the main structural framework while removing only what is necessary for renovation or redesign.
Professional contractors use a combination of:
- Hand tools
- Power tools
- Cutting equipment
- Controlled breaking methods
This ensures precision and reduces damage to surrounding areas.
Selective Demolition vs Full Demolition
Understanding the difference between selective demolition and full demolition is important for planning renovation works.
Selective Demolition
- Removes only specific parts
- Preserves main structure
- Used in renovations
- More controlled and precise
- Lower waste generation
Example: Removing a kitchen wall to create an open-concept layout.
Full Demolition
- Entire structure is demolished
- Used for rebuilding projects
- Requires more permits and planning
- Produces large amounts of waste
Example: Demolishing an entire old building for redevelopment.
Key Difference
