Financial Tribune - Homes built in Iran not only have a very short lifespan, but the environmental impact of their building materials is also harmful 

Loans worth 1,700 million rials ($13,000) will be granted to home builders who choose to use non-traditional construction methods based on new technologies this year (March 2019-20).

This marks a 54% growth in value compared with the loans offered to builders last year, a statement by the Central Bank of Iran reads.

Almost all residential units in Iran are built using conventional site-built construction methods.

“The average lifespan of homes in Iran hardly exceeds 25-30 years,” according to Fardin Yazdani, a housing expert and the official in charge of Comprehensive Housing Plan of the Ministry of Roads and Urban Development, while industrially built homes can last for up to 100 years.

Prefab technologies can be used to build homes quickly and cost-effectively, especially as traditional construction costs continue to rise, the Persian-language daily Shahrvand quoted the official as saying.

Noting that modular homes offer many advantages over site-built homes, Yazdani said the use of prefabricated components in home building, those manufactured off-site in advance, usually in standard sections that can be easily shipped and assembled, will improve the quality of buildings and help control the costs.
