House Design

The most basic part of the house design plan is the foundation. The foundation wall is actually attached to the footings or footer. You will put the footings in first and the size of the footings and how deep they are to be dug really depends on the frost level and the type of soil. The footings need to be deeper in the ground than the frost layer or the frost can expand under the foundation and push it up in places and make it uneven.

The dimension of the footings will be determined by the building inspector. The foundation wall will be attached to the footings by either pouring them together, or by pouring them separately, but joined together with rebar.
The hardest part of the house design plan is the foundation and the hardest part of that is the excavation.
