What You Don't See: The Engineering Behind The Tactile House

How spatial restructuring, concealed services, and unconventional wet-work decisions shaped our Pasir Ris project.

Our first journal entry on The Tactile House explored what you feel - the microcement walls, the wabi-sabi philosophy that shaped its material palette. This entry is about what you don't see. Because in our experience, the quality of a home is most clearly defined by the things that remain invisible.

A Home Reconfigured

This 1,119 sqft HDB in Pasir Ris was designed for a creative professional who needed a dedicated workspace at home. To accommodate this, we built a simple studio within the existing footprint - proof that functional creative spaces don't require dramatic square footage, just intelligent planning.

The bedroom layout was entirely reimagined. We closed up one bedroom entrance and hacked a new doorway between the two rooms, connecting them into a single private suite. One room now functions as a walk-in wardrobe with an integrated work and makeup area, with direct access through to the bathroom. What was once two disconnected bedrooms now operates as a complete personal suite - dressing, grooming, work, and bathing all within one continuous sequence. It is the kind of spatial fluidity typically associated with larger properties - executed here within the constraints of an HDB floor plan.

Unconventional Wet Works

The bathroom was perhaps the most technically demanding element of the project. We relocated the basin out of the bathroom and into the adjoining room - a decision that immediately made the wet area feel significantly more spacious. This is not a simple cosmetic move. Relocating a basin means extending water supply lines and waste pipes beyond the original wet zone, which demands precise waterproofing to ensure long-term integrity. Every junction, every membrane, every gradient was meticulously accounted for.

We also made the deliberate choice to omit a bathroom door entirely. Without the visual interruption of a door frame, the transition between the wardrobe suite and the bathroom becomes seamless - a single, continuous spatial experience. It is unconventional. It is also, when executed with care, quietly transformative.

The entire bathroom is finished in satin stone flake rather than conventional tiles. The result: zero grout lines, zero mould traps, and a surface that reads as a single, unbroken plane. Maintenance becomes effortless, and the visual effect is one of absolute calm.

The Discipline of Concealment

Walk through this home and you will notice how little visual clutter there is. Aircon piping, electrical conduits, and water lines have been routed to minimise exposed trunking wherever possible - integrated into joinery and ceiling structure rather than boxed in as an afterthought. Within the bathroom, certain pipes remain visible due to HDB regulations, but beyond that boundary, the home reads clean.

This is the kind of project we consider a flagship - not because it is the most expensive, but because it embodies a core belief: that the unconventional, when executed with precision, produces the cleanest results. Many homeowners want the unsightly elements hidden. We take that intent seriously from the very first drawing.

Design Tip: If you are considering relocating any wet point - basin, sink, or shower - always ensure waterproofing extends beyond the new wet zone boundary, not just the original one. This is where most failures occur, and it is a detail that should be confirmed with your contractor before any hacking begins.
