A foyer is the formal entryway or transitional space that connects a home’s front door directly to its main living areas. It acts as the "first impression" zone of a house, designed to welcome guests, set the stylistic tone for the rest of the interior, and provide a functional staging area for removing coats, shoes, and bags.

Architecturally, a foyer can range from a grand, double-height grand entrance with a sweeping staircase to a small, defined vestibule or dedicated wall niche in a modern apartment.
