The Monument Sathon.

A freehold condominium on Sathorn Soi 10 in Bang Rak, Bangkok, of 185 residences across 29 storeys above three basement levels, on a site of about 2,834 square metres. It is the third in Sansiri's Monument series, after The Monument Thong Lo and The Monument Sanampao, and the first built as a joint venture: Sansiri holds 55 per cent and Nomura Real Estate (Thailand) 45 per cent, in a development valued at THB 4.5 billion.

The developer published a range of about THB 9.9 million to THB 150 million in August 2026. Residences run from 39 square metres for a one-bedroom to 202 square metres for a three-bedroom, with two penthouses of 240 and 303 square metres. Launch pricing moves as floors and views are released, so the figure that matters is always the one confirmed for a specific unit. Ask us for the current price list.

Yes. The project is freehold, so a foreign buyer can own a residence outright within the building's 49 per cent foreign quota, the same rule that applies to any Thai condominium. Purchase funds must be remitted into Thailand in foreign currency so the bank can issue the Foreign Exchange Transaction form used at transfer. This is general information rather than legal advice, and our guide to what foreigners can own in Thailand sets out the detail.

The developer's sales materials state handover in the first quarter of 2030, as of August 2026. A date that far out can move, so we pass on whatever the sales team currently confirms rather than treating it as fixed.

Per the developer's sales materials as of August 2026: a booking fee of THB 200,000 for a one-bedroom, THB 300,000 for a two-bedroom, THB 500,000 for a three-bedroom and THB 1,000,000 for a penthouse; a contract payment of 30 per cent within 15 days of booking; and the balance at handover, stated as the first quarter of 2030. The common fee is THB 95 per square metre per month for the first two years, then THB 110, and the sinking fund is a one-time THB 800 per square metre. Terms can change between phases, so confirm the current ones against your reservation papers.

Yes. All 31 plan types are listed on this page with sizes and aspects, and we hold the developer's plan drawings for each. Use the request form under the table and a person sends them, usually within the day, along with which floors each plan is currently available on.

The Monument Sathon is available through Embark's developer network. We arrange viewings at the sales gallery, send the current price list and the layouts still available, confirm the ownership structure, and give an honest read on how a new launch prices against the completed buildings around it. We also advise on resale and rental across the Sathorn and Silom market, so the comparison is drawn from buildings we transact in.
