Making a house should be done just after you finish your profiles and journals! Need a place for the poppets to live, don't we? It is preferred that every house has at least one picture, but it's not really necessary. Just looks a tad prettier that way. What IS required, however, is a resident list. Simply make a small list at the end, beginning, wherever you see fit, listing who is currently staying there and the official owner of the building, if there is one. Be sure to include a description, however brief, of how the house looks.
