The canon house stands in a very exceptional location on the hill of Petrov in the closest neighborhood of the Brno Cathedral. It is part of a national cultural monument and is structurally linked to neighboring buildings.
During the conceptual considerations of the restoration of this U-shaped building, we were guided by the former historical use of the building. The house functioned as a canon's residence with the necessary facilities (kitchen, stables, warehouses, staff, etc.). The proposed use returns to such functions and transforms them into a contemporary standard and comfort. On the main living floor, which functioned as a piano nobile, there is again a representative apartment. More are added on all floors. In order to harmonize these necessary functions with the structure of the house, several necessary inserted elements were created. These are conceptually and materially different from historical constructions. At the same time, it can be said that the ground floor and first floor respect the historical character of the building, while the attic is a newly designed structure where contemporary architectural principles are applied.
The characteristic inserted element is the new house boarding. It connects both the rooms in this house and the neighboring houses (which was also the case earlier, as it turned out). Due to the different height levels, leveling steps had to be placed on the boarding. These stairs spread along its entire length as the so-called horse stairs. Subtle tectonics could be recognized in the exterior due to the fact that the pavilion space is unheated. The delicacy and truthfulness of the resulting structure echoes the earthiness of the original historic house.

The disposition adjustments fully respect the existing structures and positions of the windows. New constructions are designed only in necessary cases. The main intervention was the modification of the vertical communication in the entrance area and the installation of an elevator. Next, dismantling of the existing roof and replacing it with a new wood-steel structure enabling the use of the attic. As part of the modifications, the static problems of the ceilings above the 2nd floor and the overall strengthening of the building were solved.
A distinctive new element is the construction of the glazed boarding. It is suspended from above on steel rods from the truss structure and below it is supported by steel beams anchored to the facade of the building.
