In part 9 we talk about the O Soutiño house, the first house built with Ubuild. The elaboration of the project, the dialogue with Manuel and Silvia, knowing their wishes and illusions. To know the terrain well to get the most out of it and enrich the project. The manufacture of the construction elements, the moment of truth, where something new has to be definitively materialized that has not been done until now. The moment for which so much has been fought has finally arrived! You have to work very hard so that everything goes well.
