This article addresses the challenges of cramped urban kitchen spaces and cluttered storage by introducing five built-in cabinet designs. Floor-to-ceiling tall units maximise vertical space, under-counter cabinets free up worktop areas, corner pull-out baskets utilise dead corners, integrated appliance units reduce visual clutter, and slimline gap cabinets make use of fragmented spaces. It also provides local adaptation tips, cost considerations, and pitfall avoidance guides, helping households locally expand their kitchens by 10m² without demolition work, creating both practical and aesthetically pleasing kitchens.
