A conventional house addition is a multi-room structure that is built onto the side of a house and which is permanently open to the main house. When built well enough, a house addition essentially blends into and becomes the house itself.
A house addition can have many types of areas: great room, dining room, family room, bathroom, guest bedroom, or master bedroom. Rarely is a kitchen added to the addition, unless the addition is intended to be an apartment.
Though expensive, with costs rarely dipping below five figures in any market, full-size house additions typically return high value in relation to their building cost. The process of adding a conventional addition to your house is long and arduous. Often it helps to consider that you are basically building a mini-house, complete with all of the trappings of a house-build, good or bad: architect, contractor, permits, wiring, HVAC, plumbing, change orders, and more.
