Under-Window Built-In Carpentry Hacking for Residential HDB at Anchorvale Link

Project Overview

The client, an HDB owner in Singapore, engaged us to remodel the living‑room/bedroom window area by removing the existing built‑in timber cabinet that sat beneath the window. The objective was to create an open, flexible wall space that could accommodate new interior solutions while preserving the integrity of the surrounding walls, floor tiles and neighbouring units.

Our team carried out a focused demolition of the built‑in carpentry, exposing a clean rectangular cavity with bare wall surfaces ready for the next phase of interior work. By concentrating solely on the under‑window cabinet, we were able to maintain the existing floor tiling and avoid unnecessary disruption to the rest of the residence.

Technical Challenges

1. Limited Working Envelope
   The built‑in unit was tightly integrated with the window frame and adjacent wall finishes. Extracting it required precise cutting and removal of the lower framing without damaging the surrounding plaster or the window sash.

2. Structural Integrity of the HDB Wall
   HDB flats have load‑bearing walls that must not be compromised. We needed to ensure that the removal of the cabinet’s support members did not affect the wall’s structural performance, especially around the window opening.

3. Dust and Debris Containment in a High‑Rise Setting
   Working within a vertical residential block demands strict dust control to protect neighbours and common areas. The confined space under the window limited the placement of conventional sheeting, requiring a tailored containment approach.

4. Preservation of Existing Floor Tiles and Services
   Electrical cabling ran along the edge of the work zone, and the ceramic tiles beneath the cabinet had to remain intact. Coordinating the demolition while safeguarding these services added an extra layer of complexity.

Project Considerations

• Protection of Non‑Demolition Areas
  We covered adjacent walls, the window frame and the surrounding floor tiles with protective film and drop cloths before commencing any hacking.

• Dust Suppression & Containment
  A combination of low‑pressure vacuums and localized dust‑shroud panels was employed to capture particles at the source, keeping airborne dust to a minimum for the occupants and neighbouring units.

• Safety of Existing Services
  Prior to cutting, the electrical cable was identified, isolated, and temporarily rerouted where necessary to prevent accidental damage during cabinet removal.

• Communication & Documentation
  Progress updates, including daily photos and a brief written summary, were shared with the homeowner and interior designer via WhatsApp, ensuring transparency and swift decision‑making.

• Minimal Disruption to Neighbours
  Work hours were scheduled within the building’s approved renovation window, and noise‑dampening mats were placed on the floor to reduce impact on adjoining flats.

Results

The built‑in timber cabinet beneath the window was completely dismantled and removed, leaving a pristine rectangular void with smooth, exposed wall surfaces ready for finishing works.

• Quality of Workmanship – All cuts were clean, and the surrounding plaster and window frame remained undamaged, demonstrating our precision in targeted demolition.
• Timely Completion – The focused scope allowed us to finish the cabinet removal ahead of the agreed schedule, providing the client with extra time to proceed with their interior design plans.
• Client Satisfaction – The homeowner praised the low‑dust environment, the careful protection of their floor tiles, and the clear, real‑time communication throughout the project.
• Enhanced Space Flexibility – With the built‑in unit removed, the client now has a versatile wall area that can accommodate new cabinetry, shelving, or a minimalist design, adding both functional and aesthetic value to the HDB flat.
