HDB Wall Hacking and Reinstatement for Residential HDB at Choa Chu Kang Avenue 1
Services Provided
Project Overview
A typical HDB flat in Singapore was undergoing a comprehensive interior re‑configuration to create a more functional layout for the occupants. The brief called for the removal of an existing wall that separated Bedroom 2 and Bedroom 3, the demolition of multiple door frames and a low‑height kitchen partition, and the complete stripping of floor tiles in the two bedrooms. In addition, the existing bathroom fixtures (basin and toilet) were taken out, a clothes‑drying rack was removed and its hole patched, and several air‑conditioner service apertures were sealed.
Our team at HackingSG executed the full scope of Wall Hacking Services, Floor & Tile Removal Services, Door Frame & Door Removal Services, and secured the required HDB Wall Reinstatement & Hacking Permits. The works culminated in a newly built brick wall with a smooth plaster finish, sealed door openings using hollow blocks, and a freshly screeded floor ready for the next phase of interior fit‑out.
Technical Challenges
| Challenge | How We Addressed It |
|---|---|
| 1. Structural modification within HDB regulations – Removing a load‑bearing wall and several door frames required strict compliance with HDB’s hacking permit process. | We submitted detailed engineering drawings, obtained the necessary permits before any demolition, and coordinated with HDB inspectors to verify that the new brick wall and hollow‑block seals would meet structural safety standards. |
| 2. Service penetration management – The wall housed air‑conditioner ducts, electrical conduits, and plumbing lines that had to be preserved or re‑routed. | Prior to hacking, we mapped all services using as‑built drawings, carefully exposed the conduits, and sealed the air‑con holes after removal. All electrical wiring was capped and protected, preventing accidental damage and ensuring a safe work environment. |
| 3. Dust and debris containment in a occupied building – HDB units are tightly packed, so uncontrolled dust could affect neighboring flats. | We employed a layered protection strategy: floor sheeting, temporary barriers, and localized dust‑containment curtains around each demolition zone. Continuous wet‑scrubbing and a negative‑pressure vacuum system kept airborne particles to a minimum, and all debris was bagged and removed daily. |
| 4. Achieving a level floor surface after tile removal – Two bedrooms required full tile stripping, followed by a uniform cement screed to support future flooring. | After tile hacking, we inspected the sub‑strate for unevenness, then applied a bonded cement screed using laser‑levelled guides. The screed was compacted and floated to a consistent thickness, verified with a calibrated measuring tape before curing. |
Project Considerations
- Protection of non‑demolition areas – All adjoining rooms, windows, and fixtures were shielded with polyethylene sheeting and edge protectors. This prevented accidental scratches and ensured that the homeowner’s living environment remained clean and safe.
- Minimal disruption to neighbours – Work was scheduled during the homeowner’s preferred hours, and we kept noise‑producing activities (e.g., hammering, chiselling) to a reasonable timeframe. Regular updates were sent via WhatsApp, allowing the client and interior designer to track progress in
