depends on how old, and what type of building it is, putting fresh concrete slabs on takhte jamshid is not acceptable,and its happened, and if any where else in the world they do that on ancient buidlings its incorrectHey not sure if you guys realize that when renovations are done are realllly old buildings, they purposly do different shades of color so people know what old was and what new is. Common practice around the world. I saw this in germany as well.
thats different to 16th century churches and mosques or 19th century apartments
