After making an apprenticeship as carpenters in a journeymen school, M. René and Rémy COLLADELLO went touring in France and acquired expertise. After that, Rémy created his first firm in Lyon in 1956, a firm of traditional frame. But mister COLLADELLO became aware of the many advantages of glued laminated timber and decided to make manufacture and laying of this sort of timber in 1959. In 1960, he was joined by his brother, René, and they created the COLLADELLO FRERES company settled in Grésieu-La-Varenne (69) for more manufacturing. After that, they were joined by their two other brothers : Henri and Yvan.

In order to have a place more adaptable for transports of exceptional convoys, the company was transferred to Bourg-de-Péage (26) in 1979. The firm progressively stopped laying in 1984-1985 in order to make furniture only.

Now, the firm is still directed by mister Rémy COLLADELLO, seconded by his son Philippe.
