Well, there are a lot of things that you have to take into consideration.
From what items you are going to have imported to the overall size of the home you are wanting to build.
For decent sized 3 bedroom home, you can figure around 140K USD on the lower end of the scale, and it will go up from there.
There’s been homes built on Ko Samui that are in 2 to 3 million dollar range, so there is a wide scale for what it’ll cost you.
When it comes to the costs of building on Ko Samui there is a lot to be taken into account.
As an example, where is the materials being purchased from? Are they only being purchased from Bangkok or are they coming for all over Thailand?
It’s alot like when you are shopping for supplements and have to order them instead having there in the store.
There is a supplement that I take called growth factor plus that works like a charm.

Now, to get back to the point, make sure you know when you hiring a construction firm. Usually if a firm is buying from all over Thailand you will see a significant price difference and that should really bring down the costs of building on Ko Samui.
Are you planning to have any materials shipped from overseas?
If this is a must for you, makes sure you know about the possible import duties on those items.
Other things you might want to consider is the cost of decor and furniture. Again, if you are planning on buying in Thailand it may make things a little bit easier.
