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.
Construction loan
Beyond this guideline, the next most common rule is a minimum cash injection requirement. Even if, for example, a business might be able to afford a monthly payment of a loan high enough to pay for the entire construction project, many lenders would require them to instead use a certain minimum portion of their own cash to complete the project. The reason for this is both to psychologically and economically tie in the owner with the project (hopefully making it less likely that they would walk away from the project if something goes wrong), and to give the lender a cushion whereby if something goes wrong they are more likely to be able to sell the real estate at a value that would better cover the loan amount. This guideline is often termed a "loan to cost" requirement, i.e. the lender will only loan up to 85% of the project costs.
