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.
House-built engine
Such construction was also quicker to build on-site, as a pre-manufactured engine could be supplied by the engine maker in almost completed form. Skilled engine erectors were a rare resource, especially in remote mining areas, and the need to have them working on-site for long periods whilst a large house was constructed around the engine was often a cause of delays to an engine being completed. Even with adequate labour, masonry construction is a slower process than delivery of machinery alone. Where brick foundations were constructed, it was recommended that at least fifteen days were allowed before the weight of the engine was placed onto them.
