Branded residences in Thailand: the premium and the promise

In Phuket, a condominium carrying a hotel brand was selling for THB 181,000 per square metre (€4,717) in May 2025, against THB 141,000 (€3,674) for an equivalent unbranded unit. A 28% gap, measured by C9 Hotelworks in the same market on the same date. For a villa, the gap approaches double. So the question is not whether the brand commands a price — it does, and the figure is known. It is what the brand actually buys, and what it does not.

How big is this market really, and where does the figure come from?

The benchmark figure circulates widely and badly. It appears on agency websites without attribution, as "according to the latest industry studies". Its source is identifiable: C9 Hotelworks, the Phuket-based consultancy led by Bill Barnett, published its Asia Branded Residences Market Review 2026 on 16 June 2026, covering fourteen Asian countries.

Thailand accounts for THB 205.3 billion, or €5.35 billion: the value, at asking prices, of the supply launched — 13,124 units across 63 properties — not a sales volume, nor the value of delivered stock. It is up 13.3% year on year, as new projects come to market. Measured against Asia — 50,025 units and around THB 1.3 trillion, up 30.3% — Thailand's share of units launched reaches 26%, the highest on the continent.

The internal breakdown is more telling than the total. Bangkok has 5,031 units, Phuket 3,465. Koh Samui, outside branded residences in the strict sense, had 3,055 luxury holiday villas in 2025, up 37% year on year — a different scope and a different year, which cannot be added to the figures above. Hua Hin and Pattaya have destination-led supply whose volumes are not published. At the top end, Thailand fields 30 "luxury"-tier projects, against 18 in Vietnam and 13 in South Korea.

One structural detail deserves every buyer's attention: 22% of Thai supply — 3,008 units — are so-called standalone residences, carrying a brand that is not a hotel brand. The remaining 78% are attached to a hotel operating on site. The difference is not cosmetic: it determines who runs the service, who manages the rental programme, and what happens if the brand walks away.

What the 28% premium buys, and what it does not

This is the hardest figure to establish and the most useful. Only one public measurement exists, and it covers Phuket.

Three readings follow. First: the gap between primary (THB 139,000) and secondary (THB 100,000) is 39%. Part of the premium paid at launch is not recovered on resale. Second: the villa premium is of a different order from the condominium premium, because it is compared with a very low villa median (THB 70,000) that lumps together very different products. Third, and most important: no public source publishes the premium project by project, nor the rental yields actually paid out by Thai branded residences. The price gap is documented; the extra income that would justify it is not.

These figures date from May 2025. No public update of C9's residential report has been found for 2026. Quoting them without a date would be a mistake.

Where pricing power has moved

Hotels lead residential, and their 2025 figures tell of a clear shift. C9's Thailand Hotel Investment Guide (February 2026) measures, for 2025, occupancy up 0.3% in the South — Phuket, Samui, Krabi — with the average daily rate up 20.4%. Over the same period, the Central region and the North see occupancy fall 4.6%, with rates up 5.6%.

The beach-by-beach detail in Phuket is sharper still. In 2025, occupancy fell 6% across the island while the average rate rose 5%. But Kamala saw its occupancy fall 24% and still charges 40% more than Bang Tao. Surin's occupancy fell 9% while its average rate rose 21%. The market is selling fewer nights, at higher prices, to a different clientele.

This is not happening in a mechanically expanding market. Phuket airport handled 8.8 million passengers in 2025; over the first five months of 2026, traffic was flat at 3,919,885 passengers, −0.1%, with April down 9.1%. The hotel pipeline counts 41 announced or planned projects between 2026 and 2030, around 30% of them in Bang Tao and Cherngtalay; the island's total supply was expected, according to C9, to exceed 100,000 keys as early as 2026.

C9 frames the risk precisely: the issue is not arrival volumes but "the contraction in average length of stay combined with a rotation of source markets towards lower-spending visitors per night". For anyone buying a property whose return depends on short-term rental, that is the sentence to remember from the whole year.

Why wellness cannot be declared, only certified

The global wellness real estate market reached USD 876 billion in 2025 and is expected to double by 2030, according to the Global Wellness Institute (press release of 12 May 2026). It grew 23% between 2024 and 2025, while global construction grew 3%. Asia-Pacific has become the world's largest region for this segment, at USD 350 billion, ahead of North America (274) and Europe (205).

The Global Wellness Institute publishes no country figure for Thailand in its accessible releases. It says its detailed data will be presented at the Global Wellness Summit, to be held from 10 to 13 November 2026 at Angsana Laguna Phuket — the twentieth edition, and the first in Thailand. Any Thai market share quoted before then is, for now, unverifiable.

Until then, the only reading grid that holds is verifiability. Three levels, to be told apart:

The WellEra project in Bangkok, led by BDMS with Capella, illustrates the second level: it says it is targeting LEED Gold, three-star Fitwel and WELL Platinum. Targeting is not obtaining, and opening is scheduled for 2030. The grid applies to the rest of the purchase too: ask for the document, not the claim.

Two models of medical backing, two degrees of solidity

WellEra, Bangkok. Presented on 19 June 2026 by BDMS Wellness Clinic, the announced investment exceeds THB 29 billion (€756 million, or USD 865 million) on a site of more than 200,000 m² on Sarasin Road, opposite Lumphini Park. The programme combines four components: the BDMS clinic, Capella Residences (262 units, 45 floors), a 168-room Urban Wellness Retreat, and retail. Architect: Kohn Pedersen Fox. Opening announced for 2030. The BDMS group posted THB 113.272 billion in revenue in 2025, around 12% of it from wellness. The developer's strength is documented here; the programme's ownership structure is not — the release does not specify it, and it is a question to ask before any commitment.

Tri Vananda × Clinique La Prairie, Phuket. The Swiss operator announces on its website an opening in November 2026, with 40 private pool villas (Royal Villa of around 400 m², Grand Villa 160 m², Signature Villa 120 m²). It is Clinique La Prairie's first location in Southeast Asia. Conflicting timelines circulate — some publications say 2027; the most authoritative source remains the operator. The prices relayed by agencies have not been confirmed by the developer.

The Thai medical ecosystem behind these projects is real and quantified: according to the Tourism Authority of Thailand, which estimated it in October 2025, before the year closed, medical tourism was expected to generate around THB 125 billion in revenue in 2025, from nearly 580,000 foreign patients — 1.74% of international arrivals — with costs 30 to 70% below Western prices and more than 500 facilities equipped for international patients. Note that the target announced for 2026 is identical to that 2025 estimate. It is not a growth target.

The air you are buying

It is the most concrete wellness argument and the least used, because it can be measured.

For Phuket and Koh Samui, no 2025 annual average is published by a source with an identifiable method: the figures in circulation come from a publisher that names neither its primary source nor its stations. We do not quote them. The official data exist — the Pollution Control Department's Air4Thai network — and that is what to consult for a specific address.

The annual average does not tell the whole story, though. The burning season runs from February to April, peaking in March. Chiang Mai appeared among the world's ten most polluted cities three times in 2026: on 4 and 27 March, then on 16 April, when the index exceeded 150. Conversely, the pollution control agency declared Bangkok out of the critical phase on 11 March 2026. No verified 2025 annual average exists for Bangkok — so we will not quote one.

For a buyer planning three or four months a year in Thailand, the calendar of presence matters more than the annual average. It is not a comfort detail: it is a destination-selection criterion, and it can be documented.

When we model Isabelle and Marc's case

The risk the market names, and the one it keeps quiet

Bill Barnett summed up the first in one sentence, in August 2026: "You can't stay there if you can't get there." He points to the infrastructure gap with regional competitors — Vietnam, and Phu Quoc in particular — on top of rising land and construction costs.

He states the second differently: "Brand standards, operating structures, service delivery and asset management now have to be built in from day one." In other words, a brand applied late to a project designed without it does not hold. Phuket developers' margins, as C9 described them at the end of 2025, sit in the low double digits net, up to around 20% for the best projects, with gross margins frequently above 30%. The margin exists to fund a real standard. It also exists to fund a label.

What you can do now

Before any viewing, ask for three documents, not three arguments.

The brand licence agreement: its term, its termination conditions, and what happens to the project if the operator withdraws. The certificate for the announced certification — WELL, Fitwel, LEED, TREES — with its level and date of award; without it, you are in declared territory. And the statement of actual service charges for the operator's nearest project already delivered, not the projection for the one being sold to you.

For the air, one simple rule: overlay your expected calendar of presence on the February-April burning season before choosing the destination. It takes ten minutes and sometimes decides everything.
