The roofs
The roofs of the House of the Owls use a variety of architectonic solutions, whose unifiying element is the grey colour of the roof surface that mantles the house. Originally slate was used, then in the years 1915-17 the architect Fasolo replaces them with a new material, asbestos, which itself was then removed and replaced with slate, as part as the restoration works following the fire in 1991.
In contrast to the grey tones of most of the roofing, some of the canopies and parts of the roof are covered with tiles made from glazed terracotta, in vivid colours including bold contrasts of turquoise and bordeaux, yellow and green, blue and green, pink and turquoise, with the joining tiles decorated with acanthus leaves.
