In many Singaporean homes, particularly in HDB flats, the service yard is a small but important space commonly used for laundry, utility, or storage purposes. Over time, some homeowners consider hacking the service yard wall to enlarge their kitchen, create an open-concept layout, or better utilize limited square footage. While this renovation idea can significantly enhance your living space, it is also heavily regulated.
This article explains everything you need to know about hacking your service yard wall in Singapore, including regulations, approvals, risks, and practical tips to ensure the renovation is done safely and legally.
1. Why Hack the Service Yard Wall?
Hacking the wall between your kitchen and service yard can serve several purposes:
- Create a larger, more open kitchen area
- Improve ventilation and natural lighting
- Enhance spatial flow and visibility
- Modernize an older flat layout
As newer design trends favor open layouts and efficient use of space, many homeowners explore service yard wall hacking as part of broader renovation projects.
2. Is It Legal to Hack the Service Yard Wall?
The short answer: Only with proper approval, and not all walls can be hacked.
In HDB flats, the wall between the kitchen and service yard often contains structural elements that cannot be altered. HDB has strict guidelines on wall hacking to ensure the structural integrity of the building is not compromised.
In condominiums or private properties, hacking may be possible, but approval must be obtained from the MCST (Management Corporation Strata Title) and possibly BCA (Building and Construction Authority) if the wall is structural.
3. Understanding Wall Types
Before you make any hacking decisions, it’s critical to determine the type of wall:
a) Load-Bearing Wall
- Supports the structure of the building
- Usually thicker and denser
- Cannot be hacked or removed
b) Non-Load-Bearing Wall (Partition Wall)
- Doesn’t affect the structural integrity
- Usually thinner and hollow
- Can be hacked with approval
The service yard wall in many HDB flats is typically load-bearing, especially in older flats. Always check the original floor plan or consult a qualified contractor or structural engineer.
4. The Approval Process for HDB Flats
If you live in an HDB flat, here are the steps involved in getting approval:
- Hire an HDB-Registered Renovation Contractor
Only licensed contractors are allowed to carry out hacking works in HDB flats. - Submit a Renovation Permit Application
Your contractor will submit an application that includes:- Proposed floor plans
- Details of hacking works
- Method of construction
- Wait for HDB Evaluation
HDB will assess whether the wall is structural. If the wall is structural, hacking will not be allowed. In some cases, partial removal (such as creating an opening or installing a glass panel) might be permitted. - Follow HDB’s Guidelines Strictly
Hacking without prior approval is illegal and can lead to penalties, mandatory reinstatement, or even endanger the building’s safety.
5. Approval Process for Private Properties
For private homes or condominiums:
- Consult a Professional Engineer (PE)
A PE will assess the wall and provide a structural report, especially if load-bearing concerns are involved. - Apply for Necessary Permits
Depending on the extent of the work, permits may be required from:- The MCST
- The BCA (if structural work is involved)
- Engage Qualified Contractors
Even in private properties, only skilled and experienced contractors should perform hacking works to avoid damage to hidden utilities or building structures.
6. Risks of Hacking the Service Yard Wall
Hacking walls—especially those connected to wet areas like service yards—can present several risks:
- Structural Damage
Removing or altering a load-bearing wall can endanger the building’s integrity. - Waterproofing Compromise
The service yard may have underlying waterproofing membranes. Hacking without proper sealing can lead to leaks. - Utility Disruptions
Electrical wiring, gas pipes, and water pipes often run through walls in this area. Careless hacking can cause service outages or hazards. - Violation of Regulations
Unauthorized hacking can result in fines, stop-work orders, or forced restoration.
7. Alternatives to Full Wall Hacking
If hacking the service yard wall is not allowed or not advisable, there are design alternatives that offer similar benefits:
- Partial Wall Removal
Create a window or opening to connect the kitchen and service yard visually while preserving the structural framework. - Glass Panel Installation
Replace a solid wall with a tempered glass panel to allow light and visibility without full demolition. - Sliding Door System
Install a sliding or bi-fold door to separate the service yard from the kitchen in a flexible and space-saving manner. - Remove Grilles or Windows
If the service yard is enclosed with metal grilles, consider replacing them with transparent or openable panels for better flow.
8. Best Practices for Service Yard Wall Hacking
- Always Verify Wall Type
Consult the original building plans or hire a structural engineer for assessment. - Use HDB-Approved Contractors
For HDB properties, only registered contractors are authorized to carry out renovation works. - Plan for Utility Re-routing
If there are pipes, electrical points, or other fixtures, ensure proper re-routing and waterproofing are planned. - Ensure Proper Disposal of Debris
Debris from hacking must be handled by a licensed waste removal company. - Adhere to Permitted Working Hours
Noisy hacking works are restricted to weekdays during office hours (typically 9 AM to 5 PM) and are prohibited on weekends and public holidays in most developments.
9. Estimated Cost of Hacking a Service Yard Wall
The cost of hacking a wall between the kitchen and service yard typically includes:
- Hacking Works: S$200 to S$600 per wall
- Haulage and Debris Disposal: S$100 to S$300
- Making Good (Plastering, Painting): S$200 to S$500
- Re-routing Utilities (if applicable): Varies based on complexity
Total costs can range from S$500 to over S$1,500, depending on the scope of work and materials used in reinstatement or upgrades.
10. Conclusion
Hacking your service yard wall can open up valuable space and improve your home’s functionality and aesthetic. However, in Singapore, such modifications are subject to stringent rules—especially for HDB flats where many service yard walls are structural. Always start with a proper assessment, seek approval through the right channels, and hire hacking professionals who understand the legal and technical requirements.
With the right planning and expert execution, you can enjoy a seamless, compliant renovation that transforms your space without compromising safety or structure.
