This has puzzled me for a while (sad I know) but there always seem to be so many people living there and the house doesn't seem massive. At the moment we have Pat, Bianca/Tony, Children (4, not all sharing surely?) and Rickey... Also, when Denise, Kevin, Chlesea, Libby, Carly, Deano etc were there - how on earth did they all fit in?!!
Similarly, the flat above the Queen Vic must be like a tardis: until recently we had Phil/ Suzy, Peggy/ Archie, Sean/ Roxy, Billy (and Jay) and Ben - 5 bedrooms?
