The Sun reports that the Weatherfield-based soap, which is due to move to Salford Quays sometime next year, will cover the lives of families in Rosamund Street and Viaduct Street.
A Corrie insider said: "The producers plan to bring Rosamund Street and Viaduct Street into things a bit more.
"Those streets have always been on the outskirts - people are referred to as coming from there but you never see much of them.
"Now they are going to become home for a lot of new faces who will hopefully be just as popular with viewers as the rest of the cast.
"The feeling is that we need fresh characters to spin the action about."
It was confirmed earlier this month that the relocation has been disrupted due to construction problems.
