A porch is an architectural feature relating to a floor-like platform structure attached to the front or back entrance of a residence. It is external to the walls of the main building proper, but may be enclosed by screen, latticework, broad windows, or other light frame walls extending from the main structure. The porch serves as a place to pause comfortably before entering or exiting.
When covered, it not only provides protection from sun or rain but may also form, in effect, an extra exterior room that may accommodate chairs, tables and other furniture, to be used as living space.
There are various styles of porches, all of which depend on the architectural tradition of its location. Verandas, for example, are usually quite large and may encompass the entire facade as well as the sides of a structure.
