Diagonal lines found their rightful places through considerations of ergonomics in the main space with two study tables, one of which cascades into a seating bookshelf.

The inclined geometry of the staircase was taken into consideration when drawing a converging diagonal line from the wall across, which became a threshold-cabinet that doubles as a privacy screen to shield the direct view from the main door. This skewed cabinet forms a polygonal portal with the staircase and sculpts the double-volume stairwell as a triangular courtyard, delineating the front dining area from the study space at the back, thus enriching the spatial layering of the rectangular floor plan.

At the staircase's mid-landing, a triangular cabinet - in the closest matching laminate to the teakwood - was added beyond the balustrade like new growth sprouting from an old teak tree. This triangular cabinet also became the ideal location to house the Wi-Fi router in this double-storied apartment.
