1. Flat-panel door style. This is sometimes referred to as a slab-door style and is a signature element of modern kitchen design. You might see a modern kitchen using a Shaker door style, but that often falls into transitional rather than modern — which is not to say it can't be used; it's just not a purist's perspective. 2. Frameless, full-overlay cabinet construction. A bunch of terms are thrown around to describe this type of cabinet construction: frameless, Euro frameless, overlay, full overlay. They all mean the same thing, that the door overlays the cabinet box. This style is the most often used in modern kitchens because it's sleeker than a flush-inset cabinet, which is often associated with more traditional kitchen, cabinet and furniture design.
