Abstract: This invention relates to a prefabricated element (1) for a dwelling unit that is notable in that it comprises: a vertical wall (2) of approximately constant thickness comprising a front face (3), a rear face (4) and a peripheral face (5); a first lip (6) along each horizontal edge of said front face (3); a second lip (7) down each vertical edge of said front face (3); first and second ribs (8, 9) forming with the first and second lips (6, 7) a grid of cells (10) suitable for filling with insulating materials (11) and accepting an interior trim (14) to mask the entire grid; a peripheral edging (23) creating at least one bearing face and a barrier buffer; and at least first and second fixing members (20, 21) for connecting the prefabricated elements (1) to each other.
