The porch is an outdoor common area space, enclosed on three sides. Porch rooms in Orchard-Meadow and Warren Olney Halls consist of two small single rooms separated by a shared porch. In Ethel Moore Hall, porch rooms consist of one double room and a porch.

Porch rooms are primarily assigned to roommate (porchmate) pairs. If a porch room is half-occupied, the College may assign another resident to the space. In some cases a student resident may be offered the option of converting an Ethel Moore porch room to a "super single," for an additional fee.
