Abstract

La présente invention concerne un système de construction à composants complets écologiques qui est transportable par une personne et peut être construit sans nécessiter d'équipement de levage lourd. Le système comprend une pluralité de panneaux, ou d'assises, extérieurs et intérieurs qui sont interconnectables pour fournir des murs de hauteurs variables, des composants de plafond/de revêtement de plancher, et des composants de toiture. Avantageusement, les assises de panneaux intérieurs et extérieurs, les composants de plafond/de revêtement de plancher, et les composants de toiture sont fabriqués préalablement pour comprendre une pluralité de goujons qui sont prévus pour fournir une surface de fixation pour fixer des panneaux de plafond, des panneaux muraux, et analogues, et pour acheminer des conduites utilitaires.
