Exceptional villas: Phuket versus Samui

Asking prices of villa units for sale on 24 September 2026, not transaction prices. Fly over the two islands: to the west, Phuket's wooded capes drop into the Andaman Sea; to the east, Samui raises its central massif in the Gulf of Thailand. We track 616 villa developments for sale in Phuket and 208 in Samui. The real gap shows at the top: in Phuket, 164 villas ask one hundred million baht or more, spread across 51 developments. In Samui there are 13, in 7 developments. At two hundred million baht or more, the count is 37 on one side and 3 on the other.

At the end of Cape Yamu, 316 metres from its tip, The Cape Residences was completed in 2015 by Campbell Kane. 7 of its villas are for sale, at a median asking price of THB 302.2 million (€7.88 million): the highest on either island.

Medians of 9, 4 and 4 villas for sale; coastal distance as the crow flies. Further south, the coast road hugs the hills between Kamala and Patong.

Median of only 2 villas for sale. Across the peninsula, Samui comes into view, its central massif behind.

Medians per development, from 2 to 9 villas for sale each: an order of magnitude, not a valuation. Line up the ten developments by price. In Phuket, the five ask between THB 182 and 302.2 million per villa at the median; in Samui, between 80 and 250 million. From second to fifth rank, a Phuket villa is worth 1.9 to 2.4 times its Samui counterpart. 4 of Samui's five developments ask less than Phuket's fifth. A single address breaks the rule, The Estates Samui, which Phuket's first exceeds by only 21%.

Asking prices. Each island's square metre is the median of the medians of 616 and 208 developments; size, plot and price are medians per villa for sale. Per square metre, the ten developments intermingle. One hundred million baht buys between 188 and 907 m² among Phuket's five, and between 390 and 1,495 m² among Samui's. Across all villas for sale, the median square metre is THB 79,020 (€2,059) in Phuket and THB 68,054 (€1,773) in Samui: only 14% less. The difference lies in the size of the house: the median villa for sale asks THB 29.8 million (€0.78 million) in Phuket for 370 m² on a 478 m² plot, and THB 14 million (€0.36 million) in Samui for 243 m² on 378 m².

Market facts, not advice: none of these lines says what a villa will earn or what it will be worth. Buyers seeking the top of the market, a major international airport and a berth for their boat find in Phuket 164 villas at one hundred million baht or more, and established estates from Cape Yamu to the Kamala coast road. Those who prefer a smaller island, the airport a few minutes away and rarer addresses find in Samui comparable homes for roughly half the price, rank for rank: 1,200 m² at Sanh Kiri Kham for THB 80 million, while Cape Amarin asks 182 million for 1,474 m². In between, The Estates Samui is a reminder that the island, too, can reach Phuket's prices.
