Interior design has always been a reflection of the world around us—shaped by economic shifts, cultural movements, global events, and innovations in technology and materials. From the geometric glamour of the 1920s to the sustainability-driven approaches of the 2020s, each decade tells a story about how people lived, what they valued, and how design helped express identity and aspiration. Understanding this evolution not only deepens our appreciation of design history but also informs how we create meaningful, timeless spaces today.
