Schools, offices as well as mega projects are still the top users of prefab houses but slowly almost every locality in Kathmandu seems to be having a prefab house or even a room added to the already existing house.
A prefab house simple which is a one storey 3BHK house made in 700 sqft of land can cost around 20-22 lakh as per calculations done by Aiden Engineering (http://www.aidenengineering.com). Besides it being affordable this house can be build within 2 months which is less than half of the time needed for traditional homes of the same size.
