Abstract: A method of constructing a wall is shown in which vertical columns are erected by stacking a series of precast concrete elements. The elements are spaced-apart by temporary end members to define an upright passage within the column. Concrete is poured within the passage to fill the column interior. After the concrete hardens, the end members are removed to provide oppositely arranged, vertically extending recesses on the column exteriors. The distance between two completed columns is spanned by sliding a precast panel within two of the columns vertical recesses.
