This Single Story Open Floor Plan is unique in its design. Large single-story open floor plans provide space for families and entertainment; smaller layouts are ideal for first-time buyers, and cozy cottages provide inexpensive vacation retreats. Ranch house plans are a popular single-story style that practically defines the one-story home as a desirable design. Single story or single level open concept ranch floor plans, also known as ranch style house plans with open floor plans, are an especially trendy, practical, and attractive choice. Another significant advantage of one-story homes over two-story homes is their greater accessibility.
