London Broncos chief executive Gus Mackay says the Super League outfit are looking for the right venue for when they leave The Stoop.
Last week the club announced they would stay in south-west London next season.
He told BBC London 94.9: "We will continue to work with venues that want us to share their ground.
"It's a long and difficult process but hopefully in the next 12 months we can come to a conclusion and find the right place for us."
He added: "We are looking for a partner that can take us on board and work with us.
"There are a number of venues in and around London that would be keen to host us. To put those deals together does take time.
"We felt it would be best to stay another year at The Stoop to give us a little bit more time to try and find a venue that will fit where we need to be for rugby league.
"The deal on the table was for only one year.
"If we could have done a two-year deal, we would have done."
As was the case last season, the Broncos will play two of their home games away from The Stoop in 2013.
"Doing the two games on the road allows us to do some market testing," Mackay continued.
"We did Leyton Orient and Gillingham last year and in particular the Gillingham one worked very for us.
"I am sure we will go back to Gillingham for one of them but we are open for options and seeing what else is out there for the other game."
