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.
Extraordinary assumptions and hypothetical conditions
A lender may be considering making a loan to finance the construction of a house and may need to know the value of the collateral that will result. The subject property is a vacant lot, but the client needs to know what the value of the lot is or would be or will be with a house (of certain described physical characteristics) constructed on it. For purposes of discussion, we will assume that everybody expects the construction of the house to take about six months.
