Koh Samui is for sell. People from Koh Samui sell land and plots from beach and mountains. There is a lot of choice and prices very low still. Some beach plots can be very expensive example in Chaweng beach but average price still excellent for investment.

Chaweng beach have multiple construction works going all the time. Much investment people from China and other Asian countries roll in Koh Samui and make beautiful hotels and apartments around.  if you plan construction Chaweng beach or Chaweng Mountain be ready to pay 30 times normal price plots. Building will be same price in Samui, no matter area.

We ourselves recommended investment south side island where still very low cost plots and very beautiful sunset.

Only the soil itself can bring the price of the building to the clouds. If you want to know about a possible square meter price then send a picture of the building and please to tell what kind of interior will be and what kind of ground the plot is. We always make pricing with the architect and the engineer.



Let us take an example of building the steps; we are use to in Europe use multiple constructor for one project. In Thailand and especially Koh Samui construction companies do buildings from the beginning to the end. Not like base for other company and next company continued. Reasons are because construction company must be able to provide a guarantee for the construction.

Construction price in Koh Samui

We always pricing all construction in Koh Samui works on a case-by-case basis. We get constantly questioning how much the square price is. The question is in that sense peculiar because how can we know what kind of materials the customer wants the construction to do. For this reason, we do not leave a scar on what would be a standard square price. Most spectacular villa construction could square the price to rise nearly 50,000 baht. The best and easiest way is the first at all order our architectural service with complete bill of quantities, so we get a very accurate quote and price list for you.

preparing properly is half the job
