Widen by Sansiri
About the project Widen by Sansiri
Widen occupies two rai in Thung Maha Mek — Sathon, Bangkok's business centre, where no free land is left and two rai counts as a large plot for a condominium.
Two hundred and fifteen apartments on two rai is a central-district density, and here it is not a drawback but the condition of the address: in Sathon you pay not for the land around the building but for the building standing exactly here.
🔴 The developer named in the document is Siri TK Seven (reg. no. 0105566076792), a separate company rather than Sansiri PLC itself. Such a structure is common on Bangkok projects, but obligations are carried by the legal entity named in the document.
Construction began in July 2025 and handover is stated for February 2028. As of the brochure's date the land is mortgaged.
One building, thirty-four storeys, two hundred and fifteen apartments. Parking is stated at 105% — one space per apartment with a margin, which matters more in Sathorn than it sounds: parking is scarce here and its absence shows up in the resale price.
The mix runs from a 45.25 sq m one-bedroom to three-bedroom units of 143.75–209.75 sq m, with two-bedroom units of 63.75–90.75 sq m and a separate '2 bedroom plus' type of 88.50 sq m in between. The upper end is no longer an investment lot but an apartment to raise a family in, downtown.
The shared spaces sit on two levels: below, a garden with an outdoor lounge, a putting green and a pet garden; above, a sky garden, a pool facing Bang Krachao, a sauna and steam room, a meeting room and working rooms. Bang Krachao is Bangkok's green lung across the bend of the river; a view of it from the centre sells for more than a view of the city.

Where the developer contradicts itself
- The developer named in the document is Siri TK Seven (0105566076792), not Sansiri PLC (0107538000665). Both are printed: the brand sells, the company named in the document carries the obligations.
- The number of apartments (215) comes from the project page. The brochure publishes no layouts or unit areas — the passport carries none.
- The card has no photographs: Sansiri's brochures carry a shared corporate photo set, and a frame appearing in more than one brochure is not taken into a gallery. A photograph of another house passed off as this one is the very defect that cost 93 cards in August.

Who is the developer of Widen by Sansiri?

Can a foreigner own an apartment in Widen by Sansiri?
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 Widen by Sansiri has left is not published anywhere — ask the building's juristic person for a certificate before the deposit and again before the transfer.
Can Widen by Sansiri 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 Widen by Sansiri 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 Widen by Sansiri 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.
