The first step in house construction is planning and designing the house. This involves working with architects and designers to create blueprints, floor plans, and specifications for the house. During this stage, factors like the size of the house, layout, architectural style, and budget are determined.

The foundation is the base of the house that supports the entire structure. There are different types of foundations, such as slab foundations, crawl space foundations, and basement foundations. The choice of foundation depends on factors like soil conditions and local building codes.
