Decks are a mainstay of American residential architecture, especially since the introduction of pressuretreated lumber. Unfortunately, decks are often added as an afterthought and many of them end up looking like a tacked-on appendage. Even though the deck is usually behind the house, protected from street view, the design goal should still be to create a natural-looking, integrated extension of the house — essentially an outdoor room. Location, Location, Location An appealing setting for a deck is important, whether you choose the location for sun, shade, quiet, privacy, or a lovely view. The deck should also relate to a room (or rooms) where it makes practical sense and will be used — off a kitchen, breakfast area, or family room.
