Lend Lease has secured $2 billion in funding for its Barangaroo development on Sydney Harbour.

The construction and development company had secured commitments from several cornerstone investors for the development of the first two towers at the Barangaroo site, Lend Lease said on Monday.

That included $1 billion from the Canada Pension Plan Investment Board, and $500 million from the Australian Prime Property Fund, Lend Lease said in a statement.

Lend Lease will also invest up to $500 million in the project, it said.

Westpac and KPMG have already signed large tenant agreements for Barangaroo’s first two office towers, the first of which is scheduled for completion in 2015.

There had been strong investor interest in the site’s third planned office tower, Lend Lease said.
