Alternativa did not start as a panel factory. It started as a metal trader — and every hall and every line that followed was a step from reselling towards making things ourselves.

Metal, four generations back

The work of the Lemeš family goes back over 120 years, through four generations. In its earliest days Alternativa sold secondary raw materials and metal goods, from rented premises in Ilidža.
