An old farmhouse was to be renovated and fitted with modern facilities. We decided to preserve the building’s authentic features, such as the natural stone walls, timber roof trusses, and tiled roofs. For vertical circulation, we designed a staircase between two reinforced concrete slabs that extends across all floors. The attic was converted into bedrooms arranged around the new staircase. The façades and roofs were left in their original state in order to retain the charm of the historic building.
