I had a very enjoyable conversation with your highly respected architecture critic, Blair Kamin, but wanted to make the following points for clarification regarding Kamin's "'Donald calling..., A freewheeling conversation with the brash New Yorker who would bring the world's tallest building here. Sample: He'd turn the Hancock building upside down,'" (Tempo, Aug. 1): 1. The article is titled "'Donald calling . . .,'" therefore implying that I initiated the call to Kamin. Although that is fine with me, it should be pointed out to your readers that I was simply returning Kamin's call, something I suspect I will be doing for a long period of time. 2. Contrary to what your subtitle suggests, I never stated, in any way, shape or form, that the John Hancock Building should be turned "upside down." From the exterior, it has always been one of my favorite buildings in Chicago, but I did tell Kamin that having a slightly different size apartment on every floor, especially with room sizes getting smaller as the building gets higher, was both difficult and impractical. 3. With regard to the very nasty quotes about me by a certain Stanley Tigerman--this is the first time I have ever heard Tigerman's name and, until now, I thought I knew or have heard of everyone who is anyone in the real estate and design community. But I am sure that had I called Tigerman and asked for his involvement in our project, he would have given a glowing account of me. 4. Least important, I informed Kohn Pedersen Fox prior to Kamin's conversation with them that they would not be getting the job--hence their somewhat detached statement when asked whether or not they would be interested in being the architect of the project.
