Executives at the BBC are in talks over a whopping £15 million redesign.
A spot for the Islamic place of worship has been earmarked on a street leading to Albert Square, according to the Sun.
The religious building has reportedly been described as a “prominent place of worship” for the soap’s Muslim characters.
The move will trigger questions from some fans because there is no church on set.
Born-again Christian Dot Cotton currently has to hold religious meetings in Walford Community Centre.
An insider said: “The new set will be as authentic as East London today, so will including a mosque.”
The Islamic call to prayer will also be heard on the show, according to reports.
The BBC said: “The new set will better reflect the East End on screen as well as increase the potential for storylines.”
The Masoods — dad Ahmed, daughter Shabnam and son Tamwar — are the only Muslim family in the programme.
An insider also said a plot meeting about a lead character being radicalised by Muslim fanatics was “on the horizon”.
They added: “It’s been considered and discussed.
“The soap wants to be up to date and timely.
“It is a realistic storyline for an East London community.”
But an EastEnders spokeswoman said: “There are no current plans for a radicalisation storyline.”
