Method of constructing building foundation having wall structural element embedded in second foundation element located on top of first foundation element

A method for providing a finished foundation for a building, said finished foundation comprising at least one wall structural element embedded into said finished foundation, said method comprising the steps of:

• a. providing a perimeter channel defining the perimeter of the building, said perimeter having an interior portion and an exterior portion;
• b. providing a first foundation element in said perimeter channel;
• c. providing said at least one wall structural element, said wall structural element comprising a front side facing said exterior portion and a back side facing said interior portion, and a retaining flange permanently secured to the wall structural element, said retaining flange extending along substantially the entire length of the front side of said wall structural element and secured to the front side of said wall structural element, where a portion of said retaining flange extends in a horizontal direction away from the front of the wall structural element;
• d. securing the at least one wall structural element to said first foundation element such that the retaining flange faces the exterior portion;
• e. providing a second foundation element to secure the at least one wall structural element in said perimeter channel, said second foundation element being retained within the perimeter channel and the boundary of the second foundation element being defined by the retaining flange, said second foundation element having a first portion and a second portion, the height of the second portion being less than the height of the first portion and at least part of the second portion extending beyond the front side of the wall structural element;
• said method further comprising:
• f. providing at least one interior channel defining at least one interior wall of the building to receive at least one interior wall structural element embedded into the finished foundation, said at least one interior channel located in the interior portion,
• said method farther comprising
• g. providing a first foundation element in said interior channel;
• and
• h. proving at least one interior wall structural element;
• i. securing the at least one interior wall structural element to said first foundation element;
• j farther securing the at least one interior wall structural element to the first foundation element by providing a second foundation element to secure the at least one wall structural element in said perimeter channel, said second foundation element being retained within the interior portion by said retaining flange.
