<P> In an episode of Coronation Street in 2010 an editing error meant viewers could see "outside" via No. 5's (Fiz and John Stapes' house) kitchen window showing what would be a "supporting" wall (quite possibly the painted brick wall backdrop) leaning against the studio walls . In another episode where Graham Proctor announced his relationship to Tina McIntyre's ex, David Platt, a brief shot of the Platts' kitchen showed no ceiling above it . It is not the first time such errors have occurred: in one episode where Alan Bradley attacked Rita Fairclough, viewers could see a studio light in what should be No. 7's backyard . </P> <P> Furthermore, the layouts of the interior sets would be unfeasible in the exterior sets . For example, the two windows by the fireplace in the Rover's interior set don't exist on the outdoor set; the stairs to the living quarters of the Rovers have changed from right to left to left to right, the toilets would be in Ken Barlow's house and the back room would be in the middle of Rosamund Street . </P> <P> Whilst filming takes place on the interior sets, any actors appearing to walk outside (i.e. back onto the Street from The Kabin) have to stand around and remain quiet until filming has finished . This fact was revealed in the 15 May issue of TV Times magazine . </P> <P> Whereas The Rovers Return was previously an empty shell on the backlot at Granada Studios a partial interior has been constructed within the new pub at the drama serial's new home over at Trafford Wharf . This was shown on screen by actor Simon Gregson (who plays Steve McDonald) during the ITV programme "Coronation Street: A Moving Story", documenting the two - year process of constructing the new set build . </P>
