House of Two Halves is the conversion of a 1,300-square-foot dual-key apartment — a Singaporean condominium typology designed to be leased as two independent units — into a single three-bedroom, three-bathroom home for a couple, their young child and the child's grandparents. Ascend Design inverted the unit's original logic: the partition between the two sub-units was removed and replaced with a continuous living spine, while the constraints of the existing wet-work risers were retained as the organising grid for three generational zones. The interior is composed in a 1970s Mediterranean-modernist palette of burr veneer, ceramic mosaic, Calacatta Viola marble and saturated tiled bathrooms — a material language chosen for its warmth, durability and capacity to define rooms without walls.
