L'invention concerne une unité de construction permettant de construire des structures, qui comprend: un élément allongé non normalisé, tel qu'une tige de bambou ou toute autre tige végétale, et au moins un connecteur, couplé inamovible à une partie de bord de l'élément allongé. Chaque connecteur est couplé à une partie de bord respective de l'élément allongé par moulage sur celle-ci, pendant le procédé de moulage du connecteur respectif. Ce connecteur permet de normaliser le bord de liaison de l'unité de construction, en permettant de fixer celui-ci à un autre connecteur pouvant être fixé de manière amovible et normalisée.
