In constructing a home, a plurality of upwardly opening U-shaped channel members are installed onto a floor structure. Wall sections are then set into the plurality of U-shaped channel members. The result is that the U-channel members locate the wall sections. Each wall section may be pre-fabricated with lines for service (e.g. electrical lines or plumbing conduit) running through it. After the wall sections are set in place the lines for service may be , interconnected. Cut-outs may be provided at the sides of the wall sections to provide access to the lines for service to allow their interconnection.
