As a follow-up to the letter by Maxine Clark (Chronicle Letters, June 30), the Academy of Art University does indeed seem to be taking over many buildings. We have such buildings as the former First Congregational Church at Post at Mason, the Copenhagen furniture store on Van Ness, and an apartment building near Bush and Leavenworth now under the AAU banner to name a few. What next? City Hall? One final question: Are they in the business of teaching art classes or of becoming one of the biggest landholders in San Francisco???
