There are three basic forms of cure porch: attached, engaged, and inset. An attached cure porch is a structurally separate porch adjoining an exterior wall, covered by its own roof. An inset porch is built into the house itself, under a main roof; in cases where it is not entirely open, it is a porch only by virtue of the number of windows and, usually, by provision for drainage of any rainwater that enters. An engaged porch is an intermediate design— the porch is integrated into the core building, with a roof extending back over the core.
Another distinction is that between sitting out and sleeping porches. The former were smaller, designed for "sitting out" in the fresh air during the day. The latter were typically attached to a bedroom by a door with no sill wide enough to roll a bed through; the ideal sleeping porch was large enough that a bed could be turned around in it.
