It is people who decided to give structure names either old or new model, house is house. People build their based on their financial budget, the shape, terrain or structure doesn't matter much.The model of the structure is like a fashion. When I was a teenager the bell bottom pants were in fashion. Wear it now and I would look weird. That goes the same for structures whether houses or buildings. The fashion in buildings here is the so called glass building that the structure is wrapped around by glasses that would reflect the sun's rays. For the houses the bungalow is in fashion but with a large roof to cover the terrace in the backyard or even in the front yard.
