ON-A presents the Green Nest House at the Ecoconstruïm 2023 Fair. In the framework of the first Maresme Ecoconstruim Fair (27/4/2023), we had the opportunity to present the Green Nest House, a house designed by ON-A, that is sold through our own website (www.greennesthouse.com) and that we are currently launching in three sizes - S, M, and L, with 2, 3 and 4 bedrooms, respectively.
