What is a knock-down house, and how is it different from a container house?
Contents
In short
- A knock-down house has its rooms or parts made in a factory, then delivered and placed or assembled on site.
- In Thailand, "knock-down house" and "container house" are often used for the same thing, so ask the seller what the frame and walls are made of.
- Before you buy, get clear answers on the internal size, whether the price includes delivery, and how to prepare the site.
What is a knock-down house?
"Knock-down" describes something that can be taken apart and put back together. A knock-down house is a house or room made in a factory, either as a complete unit or as parts, then delivered and placed or assembled on site, instead of being built brick by brick on the land.
Because most of the work is done in the factory, the time spent on site is usually shorter than for a brick house, and in many cases the house can be lifted and moved somewhere else later.
