Four Aboda stones, one disciplined plan from Philip Mannerheim: in this Balwyn house each stone got a room and keeps to it. The kitchen belongs to Calacatta, bookmatched across the splashback and climbing the rangehood in one sweep of veining. The fireplace belongs to Grigio Carnico, its dark surround built up in nested tiers. The bathroom belongs to Bianco Carrara C, which tiles the walls and the plinth the bath stands on. And the pavers outside belong to Silver Galaxy, so the discipline holds all the way to the garden.
