NEW YORK, NY--(Marketwire - Jun 5, 2012) - Brookfield Office Properties Inc. (NYSE: [ BPO ]) (TSX: [ BPO ]) today announced that it has acquired two office towers, Metropolitan Park East & West, in the Seattle central business district for $210 million. Brookfield bought the 700,000-square-foot Class A office campus using available cash resources and an acquisition financing facility totaling $126 million.

"The Seattle market has demonstrated strong fundamentals with positive absorption over the past 18 months. The region is a leading tech and science center with a highly skilled work force. Metropolitan Park fits our strategy of owning premier assets in the best-located areas of the top urban markets and presents an opportunity to add diversification to our tenant base within the high-growth technology and social media sectors," said Dennis Friedrich, president and global chief investment officer of Brookfield Office Properties.

Metropolitan Park's two towers, located at 1730 Minor Avenue and 1100 Olive Way, are 20 and 18 stories respectively, and have a combined 867 parking spaces. Both have unobstructed views of Lake Union, the Cascades and Olympic Mountains.

Located adjacent to Interstate 5 and South Lake Union submarkets, the towers are situated in the region's largest concentration of technology and life science companies. The towers are within walking distance of the Pine Street retail center and Convention Place Station, the region's major transit hub for rail and bus travel.

The buildings are a combined 85% leased. Metropolitan Park is home to a number of high-tech tenants, in addition to large offices for Swedish Health Services and the Virginia Mason Medical Center.
