Irkutsk "pain point": 1-335 series – houses in seismic areas, demolition or renewal. Finding potential solutions on the example of Novo-Lenino district in Irkutsk

The paper examines a scenario for developing the housing sector using the Integrated Area Development Standard on the example of the Novo-Lenino district in Irkutsk. Most of the housing stock in the area comprises prefabricated housing of 1-335 series in critical condition and potentially life threatening. When applying an empiric method, the objectives were identified, and solutions were found that allow a strategy and methodology for managing a massive housing area to be developed. At first sight, the 1-335 series residential buildings look like ordinary prefabricated housing that has lasted for 50 years and will serve as much again. However, apart from the obsolescence, in half a century, the buildings have accumulated technical problems with load-bearing structures, facades (destruction of exterior panels because of atmospheric action) and civil engineering infrastructure. However, the most critical situation has arisen because these buildings do not meet the current requirements for seismic resistance; for Irkutsk, this factor amounts to 7–9 points. A number of problems related to the continued operation of such housing have arisen, which need to be addressed. One solution to this situation is a strategy for regenerating the housing sector. Replacing seismically unsuitable residential buildings with new housing estate will help create a comfortable space for living with modern architectural concepts. Legal arrangements need to be developed to ensure the feasibility of regeneration projects.
