The joint venture has agreed to purchase Perth office tower, 140 St Georges Terrace, with settlement anticipated for late June.
Primewest said it is the first joint venture between the entities and the first deal announced by Primewest since its proposed $600 million merger with Australian property group Centuria Capital.
Primewest Executive Chairman John Bond said the company was delighted to be establishing a relationship with BlackRock.
“140 St Georges Terrace is a high quality, 30,000 square metre A-grade office building at the epicentre of Perth’s CBD on the corner of St Georges Terrace and William Street,” Mr Bond said.
“A significant amount has been spent on capital upgrades in recent years and we see further value creation opportunities for the asset given our on the ground team, pro-active management approach and in-depth Perth market knowledge.
“This will be further enhanced by BlackRock’s significant global reach, experience and vision.” Mr Bond said the joint venture would immediately aim to further enhance the asset as Perth’s premier A-Grade office address with a new strategic management and leasing campaign.
He said 140 St Georges Terrace had been a high profile, gateway building in the Perth CBD for more than 40 years and would continue its pedigree and presence.
Primewest will provide project services, property management and leasing services to the JV and will provide a co-investment stake consistent with other institutional real estate mandates.
