A tile-shaped building element with recesses for forming ducts for through-feed of lines and the like, wherein at least one tube-like duct is arranged between the top surface and the bottom surface of the tile, preferably in the sectional surface between at least two sections of the tile-shaped building element lying one above the other, whereby the advantage is gained that more height levels of lines can be present and wherein niche-like recesses can be arranged in the or each side face of the tile-shaped building element for receiving a separate element (35) supporting the upper section (36). |
