The facade of a building often serves as a reflection of both the urban fabric it is set in, as well as what lies behind it. Beyond aesthetics, facades hold important functional, cultural, and sustainable significance, especially in relation to the interior design. Although natural light, views, and spatial organization are influenced by the facade, architects have been prioritizing the relationship between the building's envelope and the quality of the interior, keeping in mind current cultural, economical, and environmental changes influencing the way people design their living space. So responding to these ever-changing needs and habits, along with the focus on overall wellbeing, architects offset the facade and ceiling - and in some particular cases, floors - to create interiors within interiors; secondary envelopes that protect the interior space from the outside environment.
