Over the years, luxury living has evolved. In the 1960s, the new wave in luxury was every child in a family having his or her own bedroom. The 1970s were ruled by ranch homes with mirrored walls and whirlpool tubs. By the time the 1980s came around, expansive floor plans, master bedroom suites, and walk-in closets became the norm. In the 21st century, luxury homes are now defined by high-quality materials and appliances.
