OPEN PLAN: The main floor public spaces of a split level are ripe for renovation without touching the more contained bedrooms, baths, and lower level(s). The Open Plan Downloadable includes two open plans with subtle differences for bi-levels versus tri- or quad-levels, as well as mirror images of the layouts, so you can apply them to your home whatever its orientation. These plans are perennial favorites for opening up split level public spaces, with tried-and-true kitchen, dining and living room layouts when all the central walls come down.
