One of the grounds for demolition or reconstruction of the buildings from 19th and early 20th centuries in Moscow are wooden bearing structures, beams and girders; although in West Europe frame houses and other edifices with wooden bearing structures are preserved from much older times. There is information that architectural monuments are sometimes destroyed intentionally: Architecture and Construction of Moscow, 2005, Issue 1, p. 14; https://www.asm.rusk.ru/05/asm1/asm1_3.htm (in Russian). Another example: in the house Klimentovski pereulok 6 (completed in 1912) a puddle of benzene, poured out of a moped placed inside the house near the entrance, was found on the floor in the staircase on 2 October 2009; it was noticed by inhabitants, and the fire brigade was called. The back stairs in the same house is obstructed by old furniture and inflammable garbage; no measures are taken by the house management.
