The first mention of a prefabricated building was in 1160 to 1170 by Wace as confirmed by Pierre Bouet. In the special May/June 2015 edition of the French magazine "Historia", he spoke of a castle transported by Normans in 'kit' form. According to Bouet, Wace's epic poem Roman de Rou, verses 6,516–6,526, states: "They took out of the ship beams of wood and dragged them to the ground. Then the Count (Earl) who brought them, (the beams) already pierced and planed, carved and trimmed, the pegs (raw-plugs/dowels) already trimmed and transported in barrels, erected a castle, had a moat dug around it and thus had constructed a big fortress during the night."
