The method comprises building the wall horizontally before raising the wall to its in use upright position. The wall is made by being formed, possibly by casting, over support portions 28 each having a protrusion (76, Figure 8) in its foot that extends into what would be the base of the wall in use. The support portions may initially be attached to the wall using ties 30 but they are subsequently removable from the wall. The support portions may initially be used in the assistance of lifting and transporting the wall. The protrusions may taper upwardly and into the wall when the wall is in the upright position. Also claimed are the wall and the support portion.
