	Summary:
	The paper shows the general characteristics of restoration of national monument building on Andrassy Avenue. The article presents the renovation works of the buildings façade. The task is to develop materials, procedures and methods to be used during the restoration, and to determine it in case of using individual technology. Quote from restorer report: Hübner House was built in 1882-1884... the protruding terraces on the facades is rough limestone. The puppets are bodies of rotation. They are already badly damaged, weathered and cracked in their material. In several places, only the gypsum bark surrounding the puppet is present. The condition of the elbows is variable, in any case severely damaged and eroded. There are also larger deficiencies in several places. At their plinths, dirt accumulated on the stone slabs of the terraces clogged the carved spouts, so the moisture accumulated there accelerated the deterioration processes. Repairs with cement or lime materials can be seen in several places, but none of them could replace the original work, they are of substandard quality. In order to optimize the choice of building materials, the market supply was researched with the aim of building a time-resistant solution. We found a Hungarian gypsum patent, which is a moisture-resistant gypsum mixture, the tests of which are presented in detail.
