Sichon · Gulf of Thailand
Sichon or Samui? The mainland case.
Koh Samui has run out of large beachfront land. The coast opposite it has not. What a resort developer gets on each side of the water between them.
Side by side
The same sea, a different starting point.
| Koh Samui | Sichon (mainland) | |
|---|---|---|
| Contiguous beachfront land | Large parcels effectively gone; assembly of multiple small titles | 241 rai on 33 Chanote titles, 1,014 m of beach, one owner |
| Land cost | Among the highest per rai in Thailand outside Phuket | A fraction of island cost; rent on lease rather than purchase |
| Air access | Single private airport, 2,100 m runway inside a fixed boundary; an improvement project from Q2 2026 lifts design capacity to about 6 m passengers by 2027; premium fares | Nakhon Si Thammarat, ~60 km, new terminal built for 4 m passengers but domestic routes only today and a 2,100 m runway, with an extension to 2,600 m programmed; Surat Thani ~100 km |
| Sea access | — | ~45 min by speedboat to Samui; Don Sak ferry pier 30–40 min |
| Building rules | Strict island height and coastal limits, tight water supply | Provincial rural zone permitting tourism; 12 m coastal setback; groundwater subject to approval |
| Brands present | Saturated: Four Seasons, Banyan Tree, Ritz-Carlton, Conrad, W and more | Banyan Tree Residences Sichon (villas THB 65–85 m); Aava, Racha Kiri in Khanom; otherwise open |
| Guest profile | Established international resort market, high seasonality | Overflow from Samui, Thai domestic, emerging international; a destination to make |
| Incentives | None specific | BOI eight-year tax holiday for tourism investment in second-tier provinces |
| Infrastructure on the table | Capacity added inside a fixed boundary; no room to extend the runway | Proposed Samui–Khanom bridge, THB 74.044bn, opening 2033–34 if approved; NST airport already delivered |

What the numbers next door say
Banyan Tree's arrival in Sichon with around fifteen villas, from THB 65 million and from THB 85 million, well below equivalent island product, is the clearest signal that the mainland coast is being priced as the next tier. A 2015 desktop feasibility by an international hotel advisor, for a 350-key resort on this very site modelled a 16–17% unleveraged internal rate of return at the land values of the time; the study is in the data room. The site's scale allows a first phase of 6–15 hectares to open while the balance stays under the palms, an option Samui simply cannot offer.
What Samui still has
Brand recognition, an established international guest base, a mature villa resale market and a service workforce. A developer whose model depends on day-one rate parity with a Four Seasons should be on the island. A developer whose model depends on land cost, scale, phasing and a rising tide should look across the water.
Questions we are asked
Why develop on the mainland instead of Koh Samui?
Samui's single airport sits inside a fixed boundary on a 2,100 m runway; an improvement project from Q2 2026 lifts design capacity to about 6 m passengers by 2027, but the land around it does not grow. Beachfront there costs several times the mainland price, and large contiguous beachfront parcels no longer exist on the island. Sichon offers a kilometre of beach on one title group, facing Samui across the Gulf, with two mainland airports that have room to expand.
How far is Sichon from Koh Samui?
About 40 km across the Gulf to the nearest point of the island and about 55 km to Nathon, roughly 45 minutes by speedboat. The Don Sak ferry pier is about 50 km by road.
What is the Samui bridge?
A proposed road bridge from Koh Samui to the mainland at Khanom, the district adjoining Sichon. The Expressway Authority's February 2026 study puts it at THB 74.044bn, landing at Thong Nian in Khanom. Construction is reported for 2028–29 and opening for 2033–34. It has not reached Cabinet.
Which brands are near Sichon?
Banyan Tree Residences Sichon is in the district; Aava Resort and Racha Kiri are in Greater Khanom. The coast is otherwise undeveloped.
