Typical country homes have a front porch, dormer(s), and a roof ridge that runs parallel to the street. The most notable characteristic is a large front porch with an open rail. "Dog-house" dormers are frequently on the roof. The exterior material is usually clapboard siding. Regardless of the size of the home, they appear to be small and quaint. Historical country homes had a fireplace on either side of the home to function as the heat source. The historical country home also had a "dog trot" hallway, which was one main hallway that runs through the middle of the house, also known as a double loaded hallway. During warmer months, the front and rear doors can be opened to allow a breeze to come through and cool the house.
