CB Richard Ellis Investors recently purchased the 41-acre Northcreek Office Park in west Buckhead from the government of Kuwait for about $59 million.

The office park has four eight-story buildings. Northcreek Office Park, which is about 90 percent leased, is home of Sprint Nextel Corp.

An unusual aspect of the deal was that interested buyers were asked to submit bids in contract form instead of a nonbinding letter of intent.
