The two-story corner building bares resemblance to a collage type of construction. The ground-floor, the first-floor and the two facades that wrap them to have very little in common. Each is defined by its own structural system, with its specific materials, spatial and aesthetic attributes.

The ground floor resembles a cave like space, built entirely in arches and domes of bricks and stones. All introduced elements follow the same logic. New brick walls, new terracotta tiles on the floor and white patches scattered here and there to tie it all together.

Above, on the first floor, the same strategy. The existing wooden structure and wooden elements are complemented with more wooden beams, wooden pillars, wooden doors and their wooden frames, wooden baseboards, wooden handrails, etc. 

In both cases, the existing tectonics were brought to some degree of excess by repetition, and as a result, the distinction between original and new is made purposefully ambiguous and ultimately irrelevant. 
The two façades remained as found. White tiles and painted plaster.
