Former Lendlease executive Tarun Gupta is moving fast to reshape Stockland Group, bringing in international third-party capital and dealing with the problematic retirement business that dogged his predecessors.

On Wednesday, Gupta announced three deals that will allow the company to accelerate the expansion of $4 billion in land lease residential projects, bring forward the development of a $765 million science and technology park, and generate $987 million in capital from pulling out of retirement living.
