Foundation (engineering)
A foundation is the element of a structure which connects it to the ground, and transfers loads from the structure to the ground. Foundations are generally considered either shallow or deep. Foundation engineering is the application of soil mechanics and rock mechanics (Geotechnical engineering) in the design of foundation elements of structures.
Bungalow
On a per unit area basis (e.g. per square meter or per square foot), bungalows are more expensive to construct than two-story houses, because a larger foundation and roof area is required for the same living area. The larger foundation will often translate into larger lot size requirements, as well. Due to this, bungalows are typically fully detached from other buildings and do not share a common foundation or party wall: if the homeowner can afford the extra expense of a bungalow relative to a two-story house, they can typically afford to be fully detached as well.
