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.
Richmond District, San Francisco
To lure home buyers with promises of large houses while keeping prices low, homes were built with large basements (basements are an unusual feature in California because its weather permits shallower foundations) with the intention that the buyers could convert the basements into living space at their own volition. This essentially marketed a house as two stories, with the first story (basement) unfinished. This decision would prove to be ingenious as the 20th century evolved, as many basements were converted to garages. Some were converted with garages in the front and in-law units in the back.
