Winner of the ABCEM 2010 Award from the Brazilian Association of Metal Construction, Casa EC stands out with its upper volume made of steel structure. Located in a privileged spot with views of a lake and the Serra Geral, Casa EC was designed for a couple and their three young children who enjoy hosting friends. While the main living areas are situated on the upper floor, including the kitchen of the old house, reproduced at the client's request, the garage and party room are connected to the existing pool on the ground floor, emphasizing the social aspect of the house. In the entrance hall, a metal staircase with independent structure steps connects the two levels.
