The company posted a pre-tax profit of Â£539.7m for the year to the end of April, up 42% on the previous year.

But Berkeley warned of upcoming potential uncertainty amid plans for a referendum on Britain's membership of the European Union.
"We welcome the stability in central government following the general election and the commitment to increase housing supply, but political uncertainty remains with the London mayoral election and referendum on Britain's relationship with Europe on the horizon," said chairman Tony Pidgley.
The company supports the UK's membership of the EU.
It said that staying in the EU is "the best way for London to remain a world city".
