I'm very interested in how you get on with this. My dream's to build a house but it's just not possible in the UK as it has some of the strictest planning laws in the world. Not only that but in the cities, it's hard to find space and if you do, it's far too expensive whereas the countryside is incredibly cheap but impossible to get planning permission unless you work the land. No amount of coffee money could get you planning permission to build a dream home in the countryside in the UK.
As much as I love the idea of shipping containers for cheap and quick buildings, I don't see them working that well in Vietnam. Structurally, they are quite weak when cut up and the amount of material you need reinforcing it, you might as well not have bothered. See it makes sense in a country that's expensive to build but not in Vietnam. I don't know where everyone is getting the 40,000 USD figure. I've been looking at this stunning 2 storey that was designed by architects, total costs including construction material, labour and the furnishing came up to 21,800 USD and this is in Hanoi, 2016 where I assume construction costs are highest. The cost of a shipping container in the UK is about 5000 GBP for the largest one. You'd need a few of those so the maths just doesn't work.

One thing to bear in mind is the value of your place if and when you want to sell it. Recycling shipping containers is not perceived as the same cool hipster place to live in these parts of the world. In China, only the poorest in society live in shipping containers. I've seen rural migrant workers live in them on construction sites outside Shanghai. Ironically, they are living in them on construction sites where they work on luxury condos and townhouses for the rich. I don't know about Vietnam, but I did tell my GF I wanted to do something like this and she said only poor migrant workers live in shipping containers. She couldn't understand why someone would build a house using them.

Me, I personally love it. One of my favourite Grand Designs is this shipping container home. You might get a few tips from watching it.

I'd like to know if it's possible to get Cross Laminated Timber prefabs manufactured in Vietnam and whether it's suitable for tropical climates. I know it they use it now in Singapore and Japan but I doubt it's available in Vietnam yet.
Goodluck to you and show us how you get on.
