The Traditional New England Saltbox has long been considered one of the most attractive designs in Colonial New England architecture.
Adding a single-story lean-to shed to the back of a one-and -one-half or two-story, one-room deep house was the most practical method of gaining more space.
The resulting shape of this new house was that of a medieval saltbox, hence it's name. By 1680, the Saltbox Style had become so popular that houses were being built with the lean-to as part of the original construction, with the roof line unbroken from the ridge to the rear wall.
The saltbox is the original passive solar house design in New England. A very energy efficient house can easily be designed using stress skin panels and efficient modern heating units.
