It concerns the project in Vasilis Street 2 and Ap.Pavlos in Thiseio. All studies and work had to be done, with absolute respect to the suggestions of the newer monuments authority. The cleaning of the marble hammered elements, from dirt, as well as fire debris were factors, which made the maintenance extremely demanding and time-consuming. Several exterior decorative elements, which had been arbitrarily added and altered the character of the building, were removed. Another interesting challenge was the design and construction of the external windows and railings, which are compatible with the character of the building.
