G Residence is built using a beam-and-column system with cast-in-place RC walls that define both façade and interior partitions. A solvent-based sealant is applied throughout, ensuring watertightness and sealing surface cracks.
Formwork marks and joint lines are deliberately left visible, embracing the concrete’s raw, honest finish. Floor and roof slabs are poured in place, with services concealed within the structure.
Low-emissivity skylights soften daylight and reduce heat gain, while glass block walls—used in place of brick—respond to local codes and lighting needs. Solar panels form a layered roof, offering shading and energy efficiency.
The G House is the second iteration of A01’s home-gallery typology—a self-commissioned canvas for refining our spatial and material ethos.
Concrete is celebrated in its raw, unfiltered form, with every surface preserving the memory of its making—from plywood imprints and tie-rod holes to subtle tonal shifts from curing. Services were meticulously integrated within the structure, leaving each imperfection as a quiet trace of process and craft. The construction, spanning 2.5 years, reflects a deep commitment to detail: from Japanese concrete studs and ultra-thin aluminium-framed windows to rare imported stones, mirror-finish stainless steel, and bespoke local furniture. Glass blocks sourced from Indonesia lend the house its distinctive character—diffusing light, casting shifting patterns, and balancing privacy with openness.
Organised vertically, the house unfolds as a sequence of living, working, and reflective spaces. The ground level opens to a naturally ventilated multipurpose area and pool, fostering a dialogue with the landscape. A soaring double-volume living space anchors the first floor, with a suspended mezzanine office and library bridging work and rest. Private bedrooms sit quietly above, while guest rooms nestle beneath the pitched attic roof. A generous central courtyard connects all levels, drawing in light and greenery, with the staircase and lift spiraling around it in an experience of unfolding nature.
Set opposite a richly ornamental Oriental house, G House’s austere form and restrained palette offer a quiet counterpoint—underscoring Singapore’s layered architectural landscape and the coexistence of contrasting spatial identities.
