An attachment system and method for coupling a wall and a floor together during and/or after construction, and for facilitating final orientation of the wall and floor, includes first and second members coupled to the respective wall and floor and pivotal about a hinge member. The wall and floor, and thus the first and second members, pivot between an assembly position, and a final position. In the assembly position, the wall or the floor is assembled, and the first and second members are coupled to the respective wall and floor. In the final position, the wall and floor are finally oriented with respect to one another.
