Prefab are building manufactured offsite in controlled environment. That way the building process won’t be delayed or affected by factors that would come into play on the actual site where the building is to be constructed. Different parts of the house are manufactured in standard sections offsite and once complete are assembled and constructed at the site. They are easy and less time consuming to build and dismantle.
Prefabs in Nepal have been a thing going back as early as the early 90s. The concept and services were there and a few companies were built around the concept however the trend failed to gain any popularity for a long while. It was only through a tragedy that the prospects of Prefabs were truly considered when the nation was struck with two massive scale earthquakes in the April of 2015. The infrastructures were in ruins and the people needed a quick and cheaper substitute immediately following the event.
That’s where people remembered the Prefab homes. Yes, they were doing slow business despite the occasional attempts to popularize the concept from really early on, but the demand for Prefab homes skyrocketed following the earthquakes. Companies like Prefab House Nepal, Himalayan pre-fab, Interior Point Nepal and many more started offering the service. People were homeless and in desperate need for shelter and prefabs fit the criteria pretty well. They are earthquake resistant, strong, easy and faster to build, costs a lot less and much more.
They gained more popularity in the rural areas of Nepal, especially Prefab School as lots of them were built as immediate substitutes. Before the earthquake prefab homes were mostly used in project based constructions like hydropower stations, organizational buildings or to make villas and such. People, especially in the urban capitals were skeptic about legitimacy of these homes over safety and security concerns and the fact that the capital especially was an earthquake prone zone. Not many were aware of the fact that Prefabs are designed to withstand earthquake shockwave or that using Expanded Polystyrene (EPS) in the construction materials makes prefabs fire and water –proof. Plus with the right materials and expenditure they can be luxurious dwelling place too. I mean we did mention them being used to make villas did we not?
The lifespan of Prefab homes can go from anywhere between 25 to a 100 years depending on what materials were used and what kind of elements it faces on site. However they’re warranted usually from 15 to 35 years. And if you think they’re small then well they can be made up to 3 stories high.
