The house in the three photos below is approximately 1500 square feet. It includes a kitchen, great room, mud room with laundry, bathroom and a home office on the first floor. On the second floor is a large exercise/TV room, a small bedroom with sleeping loft, a medium bedroom, and a second bathroom. In the basement is a full woodworking shop and a root cellar.
Later additions were an elliptical window in the gable end, two south facing dormers, a sunroom/greenhouse/woodshed and a deck out back.
This house can be heated through a tough New England winter with one tank of oil and one cord of wood. Bigger isn't always better!
I built many houses throughout Franklin and Hampshire counties as a lead carpenter for several different builders in the 80's and 90's. Below are a couple examples.
