Split level floor plans brought home both unique opportunities and unique challenges. The first step in evaluating the opportunities and challenges are split-level understanding of the type you are planning to renovate.
There are essentially type split level floor plans: Split Foyer or Bi-Level consists of two levels, with the inclusion of the mid-level between the two floors. A short flight of stairs (normally 4-8) ride and another short flight of stairs down, if the lower level of the house was built parallel to the ground, there will be stairs to the entrance. The lower level may be at least partially below ground level.
