[Object] To provide a building material, a stacked body of building materials, and a building-material construction method capable of improving the construction properties while suppressing a design surface from being damaged. [Solution] A building material includes a substantially rectangular plate-shaped building material body 2 that includes a first face 2F and a design surface 3 within the first face 2F; and a protective sheet S1 that is affixed to the building material body 2 in a peelable manner. The design surface 3 includes a covered region C1 that is covered with the protective sheet S1 and thereby protected and an exposed region B1 that is not covered with the protective sheet S1 and that extends along a first design end portion 3D, which is an end portion of the design surface 3.

An example pre-assembled wall panel may include a panel frame which includes a plurality of studs connected to opposing end members, first and second wall boards connected to opposite first and second sides of the panel frame, a plurality of spacers attached to at least one of the first and second wall boards and configured to support a finish panel in a spaced relation from the at least one of the first and second wall boards; and a pipe disposed between the first and second wall boards and extending between the opposing end members, wherein the pipe includes a pipe diverter, and wherein a free end of the pipe diverter passes through an opening in the first wall board or the second wall board.
