The house that hosted each time the project’s head or the chief engineer was special because of its construction’s quality and its view. This rectangular-shaped residence consisted of two floors and a large and verdant garden. Thanks to its architecture, two families could live there, occupying one floor each. The upper floor had a small terrace overlooking the lake. In its interior, there was a large hall lined with red and white tiles. A wide wooden imperial staircase led to the upper floor, while on the ground floor there was the kitchen, a small bathroom, and a room, as well as the hallway.
