The overall architectural design of the house is preserved. The extension is designed in the back of the plot and doesn´t appear in the main street view. The extension is a replica completion, connected to the ground floor, covered by a flat roof. Atics reproduces the structure of the original concrete balustrade. On the roof is a walk-in terrace with a large-format concrete tile surface, accessible from the floor. The extension is plastered in the same design as the existing family house.
