Many have the custom to recite Hallel in the synagogue on the first night(s) of Pesach, at the end of Arvit. (Discussed, for example, in this question and its answer.)
Is this custom only to be observed in a synagogue setting? Can / should an individual praying alone (for whatever reason) also recite this Hallel after praying Arvit, before beginning his seder? If yes, does he make a blessing (assuming that he would ordinarily recite a blessing on a recitation in the synagogue)?
