Last month, The Observer reported on developer Harry Macklowe's recent buying spree.

In addition to purchasing a townhouse at 53 East 77th Street for $15.75 million, Mr. Macklowe reportedly plans hotel and luxury condominium developments in the East 50's.

Now, Peter Slatin reports that Mr. Macklowe has just purchased two units at The Plaza. Perhaps, not as a coincidence, the luxurious apartments face the General Motors Building, a skyscraper across Fifth Avenue that Mr. Macklowe bought for $1.4 billion a few years back.

As with the townhouse purchase, Macklowe Properties is not saying a word about the company's plans.
