XT Phayathai
About the project XT Phayathai
XT Phayathai stands on Sri Ayutthaya Road in Ratchathewi — central Bangkok, where BTS Phaya Thai meets the Airport Rail Link. Two towers of forty-one and thirty-seven storeys on three rai, one thousand four hundred and thirty-five apartments.
The mix covers both the studio format and the family one: one-bedrooms of 25.25–49.75 sq m, two-bedrooms of 61–101. An upper bound above a hundred metres in a building by the station is unusual — land like this normally goes entirely to small lots for letting.
The shared part is urban: a pool, a gym, a library, co-working, a function room and a garden, round-the-clock security and CCTV, an EV charging station. The project was built jointly with Japan's Tokyu Corporation, a partnership Sansiri has run since 2014.
The building is finished and occupied. Per the developer's annual report, at the end of 2024 construction stood at 97% and 87% of the apartments were sold; the project value is 9.5 billion baht.

Where the developer contradicts itself
- Apartment count: the developer's catalogue and project page state 1,435, the 2024 annual report 1,436. The catalogue figure is printed.
- The brochure has no text layer at all, so the card gives no title deed number, mortgage status or construction dates. The figures come from the developer's project page and annual report.

How many apartments are there in XT Phayathai?

Where is XT Phayathai located?
XT Phayathai is located in Ratchathewi, Bangkok, Thailand.
Who is the developer of XT Phayathai?
The developer of XT Phayathai is Sansiri.
Can a foreigner own an apartment in XT Phayathai?
Yes, within the foreign quota: under the Condominium Act B.E. 2522 foreigners may hold up to 49% of a building's total saleable floor area, and the Land Office checks the ratio at the moment of transfer. How much of the quota XT Phayathai has left is not published anywhere — ask the building's juristic person for a certificate before the deposit and again before the transfer.
Can XT Phayathai be bought on a leasehold?
Beyond the 49% foreign quota apartments in Thailand are sold on a leasehold — a lease right of up to 30 years registered at the Land Office. Renewal is a clause in the contract, not a guarantee given by the law, and it is registered anew each time. Whether a leasehold is available in XT Phayathai right now, and on what terms, is a question for the developer.
Do I have to come to Thailand for the deal?
Not necessarily: the transfer can be done by a representative under a power of attorney certified at a Thai consulate. Money for a foreign-quota purchase must arrive in Thailand in foreign currency through a Thai bank — the bank's certificate of that transfer is required at the Land Office (Condominium Act, section 19).
What is paid on top of the price of an apartment?
The transfer is paid for at the Land Office, and the building charges a common area fee monthly and a one-off sinking fund payment. The rates for XT Phayathai are on this page where the developer publishes them; taxes and the transfer fee depend on the seller and on how long the unit has been owned.
