But wait, there's more.

Microsoft this morning announced an even broader expansion of its Puget Sound real estate holdings. In addition to the west campus expansion, detailed in Sunday's stories, the company gave shape to its leased property portfolio.

Microsoft intends to lease 21 additional sites in Bellevue, Issaquah, Redmond and Seattle, "which will provide a combined total of 5.5 million square feet and the capacity to house approximately 19,000 people," according to a press release issued this morning.

It was unclear how much of that includes already announced sites in Bellevue, where Microsoft has locked up about 1.6 million square feet of top-end space in Lincoln Square, Advanta and Bravern. The company also detailed its footprint in downtown Seattle earlier this year. Also, the tenant for a 1.5 million space Paul Allen's Vulcan development group is building in South Lake Union has yet to be officially confirmed, though it's widely believed to be Amazon.com. (When I asked Microsoft real estate boss Chris Owens about this recently, he had no comment.)

The company also is planning additional new construction at the Redmond campus, including two new buildings on the Safeco campus it acquired in 2006 and additional new construction on the 26-acre parcel adjacent to its RedWest campus it bought from Nintendo for $42 million. The timing and size of these developments were not disclosed.

The company provided updated figures for its work force. Locally, it now counts more 36,000 workers, out of more than 82,000 globally.
