I really like this name. It has the trendy -iah ending like Josiah etc., as well as great nickname potential (Ben, Benny). The Naya ending could sound feminine in some circles, but I don’t think that makes it a feminine name.
Though the translation given for this name is a correct translation. The normal translation for this name is 'son of G-d'.This is because in Hebrew the words for 'son' ['ben'] and 'builder' ['bone'] are very similar due to the concept that the children are the builders of the future.
