Split-level homes evolved out of suburban ranch homes of the 1940s. A ranch house with flair, the split-level house, or split foyer offered more space for baby boomers. Buyers of today love these family-friendly homes because of their locations in family-friendly neighborhoods. Modern renovations to the split-foyer design typically consist of a kitchen remodel, larger energy efficient windows and renovations that extend the second story across the entire length of the house to make room for a large master suite. The split-levels of the 1950s are fast becoming an American favorite home style.
