In early September 2015, the Romanian superior chamber of Parliament adopted the legislative proposal Law 252/2015 amending and supplementing the Law no. 50/1991 authorizing the construction works, the project now being in the Chamber of Deputies committees. The main amendments relate to the way of the authorizing of intervention in protected areas. Under the proposed legislation, will be established a separation of monument buildings in protected areas due to differences concerning "the nature of the building." According to representatives of the Bucharest Territorial Branch of Romanian Architects Order (OAR Bucharest), the proposal omits, however, some elements which link all the articles which refer to interventions in historic areas, creating dysfunctions at procedural level.
