The statistics on renovation building describe the renovation activity of building construction annually. The data concerning the value of renovation building are obtained from the financial statements of hou-sing corporations and the largest construction companies. The renovation building of housing corpora-tions is divided into two parts: renovation building of housing companies and renovation building of state-subsidised rental dwellings. The statistics on the renovation building of construction com-panies cover the renovation activity of construction companies employing at least 10 persons. The statistics also contain information about the targets of renovation buildings.
