House with Chimaeras
Due to the steep slope on which the building is situated, it had to be specially designed out of concrete to fit into its foundations correctly. From the front, the building appears to have only three floors. However, from the rear, all of its six floors can be seen. One part of the building's foundation was made of concrete piles, and the other as a continuous foundation. Usually, these two approaches do not mix well but Horodecki somehow succeeded in overcoming this technical problem.
Foundation (United States law)
The Tax Reform Act of 1969 defined the fundamental social contract offered to private foundations. In exchange for exemption from paying most taxes and for limited tax benefits being offered to donors, a private foundation must (a) pay out at least 5% of the value of its endowment each year, none of which may be to the private benefit of any individual; (b) not own or operate significant for-profit businesses; (c) file detailed public annual reports and conduct annual audits in the same manner as a for-profit corporation; (d) meet a suite of additional accounting requirements unique to nonprofits.
