Claim:
A building element in the form of hollow brick comprising: a structure formed of a frangible material, said structure comprising: a plane major face and dovetailed projections on an opposite major face for slotting together with similar building elements for the construction of masonry structures, internal through cavities for housing of operative connections of distribution systems; and said through cavities arranged according to an array parallel to said plane major face and in that said plane major face is formed with references thereon for identification from outside of said structure a location for each of said through cavities; a first reference of said references on said plane major face identifying a first through cavity of said through cavities, said plane major face being configured to be broken at a location of said first reference to allow a removal of a first portion of said plane major face to allow access to said first through cavity from outside said structure; said first through cavity is bounded by at least one inner frangible partition wall, said at least one inner frangible partition wall being continuous such that said first cavity avoids communication through said at least one inner frangible partition wall with a second through cavity of said cavities or with said outside of said structure.
