Costs more to build out. As you said, there are all kinds of other factors, but the same square footage in two stories will cost less to build than in one. Most homes with traditional foundations can sustain a second floor addition without additional support.
Consequently, a larger home may have a lower square footage cost than a smaller home. Also, it usually costs less to build a two-story home when compared to a one-story home that has the same square footage. This is because a two-story home will have a smaller roof and foundation.Plumbing and ventilation are more compact in two-story homes.onsequently, a larger home may have a lower square footage cost than a smaller home.
