To maintain the original square footage of a building plan, you must increase the overall dimensions of the house, which also impacts the design of the roof and foundation.

In general, most interior walls are 4–inch–thick studs, or two 2–inch by 4–inch pieces of lumber placed side by side.
These studs are usually spaced 16 or 24 inches apart, and the space between them is filled with insulation and drywall.
Exterior walls can be thicker, depending on the climate, the type of material used, and the building code. For example, in areas with extreme cold, exterior walls may be up to 8–inches thick, with extra insulation, while in areas with milder climates, they may be as thin as 4–inches.
The purpose of a wall also affects the thickness. For example, load–bearing walls, which support the weight of the structure above them, are generally thicker than non–load–bearing walls. Walls that are designed to provide soundproofing or fireproofing may also be
