Koh Samui is an absolutely gorgeous place to settle down, and the beauty and the beaches of the area make it a place in high demand. Unsurprisingly, many people clamor for plots on the island, particularly those on the beachside, and as a result, the prices are rather high. Prime beachfront locations can cost as much as $4 million, while less in demand regions further away from the shore is only about $500,000. Island real estate is in ridiculously high demand, and it shows in the pricing of these premium plots.

However, it is important to know that the straight-up purchase of land on Koh Samui is difficult. Most land is owned by the residents, and it is a very popular scheme to lease the land from the owner rather than purchase it outright. Prices for the actual construction vary between companies, and it is important to search around extensively for the company that works best for you.

How Long Does Construction Take?

Foreigners cannot own land, but they can own the structure they build on top of it. The land must either be leased or purchased by a Thai establishment. The first thing that needs to be done on Koh Samui when intending to build a structure is to obtain a building permit, which takes at least 45 days to have processed. Following that, there are numerous other steps that need to be taken, but these are best handled by your builder, who can expedite the process with their good relations with the people of the area.

Actual construction of a building is, of course, dependent on the contractor you decide on, and how readily available the funds are for construction. It is also a good idea to have a lawyer verify all legal documents to prevent any issues or scams down the line. The land on Koh Samui is too expensive to be scammed out of it.

Koh Samui is an absolutely gorgeous spot for both tourists and foreigners looking for spots for business investment or a place to settle down during the holidays or permanently. Due to the high demand of the land for real estate and the efforts of the government to avoid wild encroachment of the beautiful island with new buildings, a lot of hoops must be jumped through to finally be ready to build on Koh Samui. However, if you follow all the building regulations shown above, and do business with a reliable contractor, your dream house on the island will soon be a reality.
