 The second series of Inside No. 9 was filmed from the end of 2014 into early 2015 . " Nana 's Party " was filmed in January , and was the final episode of the second series to be filmed . The writers saw a number of houses before selecting the one used in the episode ; they wanted an open plan home to allow for easy movement between rooms . The one chosen was close to Twickenham Studios . A " deckhouse " was added to the house 's garden ; despite there already being two sheds , neither would have been visible on @-@ screen . A new one was thus added . The executive producer Adam Tandy suggested that deckhouse would be preferable to shed , as the latter term suggested the site of something awful . Scenes in a bedroom used the room mostly as the production team found it . The room featured a number of books not seen on @-@ screen , which reminded Shearsmith of a script ( in the end not used for Inside No. 9 's second series ) of an episode set in a library . The front room had a buffet , including a prawn ring ; by the third day of filming , this had begun to smell , and needed to be removed .
