I'm looking for quotes and advice from US-based interior designers about how opting for vertical wood panelling on cabinets, long floor panels and vertical tiling on walls in a kitchen can create the illusion of height to balance a long, slim space. I'm also interested in how to break up the linear look - such as solid marble countertops or metallic panels, as well as why lighter colors, such as soft pastel shades and neutrals, work best for this trick.
