It is reported that A-listers Beyoncé and Jay Z have made a $120m offer for a California mansion which is part of the property portfolio of Irish developer and estate agent Tyrone McKillen.
McKillen - the son of Belfast-born property magnate Paddy McKillen - has the eight-bedroom, 11-bathroom residence on Bel Air's Cuesta Way on the market for $135m. It has been designed by an in-demand Irish architect, Paul McClean.

Los Angeles real estate news website the Real Deal reports that if Beyoncé and Jay Z's bid is accepted, it will break the record for the most expensive home in Los Angeles and its environs. It says McClean designed at least three of the 10 most expensive homes sold in Los Angeles last year.
Dublin-born McKillen's 30,000-square-foot Bel Air property consists of six structures and boasts four swimming pools, a basketball court, a recording studio and a spa. He is also the agent on the property through the real estate company Hilton & Hyland.

"It's got beautiful scale, beautiful volume," said Jeff Hyland of Hilton & Hyland.
Hyland told the website that it had taken McKillen and his company McKillen Developments about four years to finish the property. The site was purchased for $15m in 2013, when a 9,400-square-foot house was on the grounds.
"They tore it all down [and] did the existing house a favour," Hyland said.

But even if Beyoncé and Jay Z's offer is accepted, Hyland added that the record would not last long as "the bar keeps getting raised" for mega-properties.
"From now on, every time there's a major high-end sale, it will break the existing record," he said.
It is reported that this is the third time Beyoncé and Jay Z have bid for a home in the Los Angeles area since 2014. The music moguls need a bigger house, having announced in February that they have twins on the way to join big sister Blue Ivy.
