The Londoners, who were effectively homeless after leaving the Twickenham Stoop at the end of the 2013 season, averted the possibility of going into administration by clinching a two-year ground-share agreement with Barnet FC.
In addition to playing their home games at the £26million development at The Hive, the Broncos will switch their training to Barnet's former ground, Underhill.
The next step for Rea will be to assemble a squad ready for their opening match of the 2014 Super League season at Widnes on February 16 after watching 16 of last year's squad leave the club.
Rea is thought to have drawn up a list of targets and is set to announce the appointment of former St Helens and Great Britain scrum-half Sean Long as his assistant.
The club are expected to receive special dispensation to exceed the overseas quota and will make use of the loan system to borrow players to get them up and running.
It would be no surprise if the Broncos were to recruit from Bradford, who have made it known they are prepared to sell players to relieve the financial pressure on their club.
Friday's announcement was the culmination of six months of talks which followed speculation that Broncos' long-term chairman and benefactor David Hughes was looking to wind down his commitment to the club.
Hughes is set to remain in charge of the Londoners during the 2014 season, with Barnet chairman Kleanthous expected to assume control for 2015.
Hughes said: "Our focus has always been to ensure we made the right decision going forward.
"Over the last 10 days, we have worked closely with the Rugby Football League and Barnet chairman Tony Kleanthous to avoid administration and secure the future of the Broncos.
"I believe this is the right decision, not only for the club, but also for the future of rugby league in London."
