Outdoor Spaces
> DECK From shipbuilding: an open, outdoor area with a floor, often wood. A pergola-roof or awning may offer partial coverage. A deck is usually at or near grade (ground level) and thus does not require a railing. (Raised and second-level decks do.) A deck is most often connected to the house, although a raised, floored platform in the yard may be considered a deck. Also: porch flooring is called a deck or decking.
> PATIO From a Spanish word for courtyard, a paved area accessible from the house, at ground level and with neither railings nor roof. The paving may be flagstone, cobble, brick, concrete, tile, or packed gravel.
> PORCH A roofed shelter attached to the house, with a door to the interior. Near-grade porches don’t necessarily have railings, but most old-house porches do include a balustrade or shingled knee-wall as part of the enclosure. Porch variants include portico, piazza, loggia, arcade, gallery, and verandah.
> STOOP From the Dutch stoep (step), it comprises the stair-steps and landing in front of an entry door.
