The Monument Sathonis a 185-residence freehold condominium on Sathon Soi 10 in Bangkok, developed by Sansiri and Nomura Real Estate (Thailand) in a THB 4.5 billion joint venture, with homes from 39 to 303 square metres priced from about THB 9.9 million to THB 150 million. It is the first project the two firms have built together, and the third in Sansiri’s Monument series.
The partnership
A Thai developer and a Japanese partner, and what each brings.
Read the full explanation
Sansiri holds 55 per cent and Nomura Real Estate (Thailand) 45 per cent. For Nomura, one of Japan’s largest developers, it is a first tie-up with Sansiri. Japanese capital in Thai luxury residential is not new, but it tends to arrive where the buyer is expected to hold rather than trade, and it brings an expectation about build quality and after-sales management that Thai buyers have learned to read as a signal.
The building
- 29 storeys above three basement levels, on a site of about 2,834 square metres
- 185 residences, one to three bedrooms, from 39 to 202 square metres
- Two penthouses, of 240 and 303 square metres
- More than 100 per cent conventional parking, rather than stackers
- Close to one rai of green space within the plot
- Freehold, and pets are welcome
The stated concept is “Monument of Nature and Heritage”, built around the greenery, the history of Sathon Soi 10, and a design intended to age slowly. The parking detail is worth noticing: conventional parking at over 100 per cent of unit count is expensive to build and is one of the quieter marks of a project aimed at owners rather than investors.
What the renders show
Computer images, not photographs. What they do and do not commit anyone to.
Read the full explanation
The released renders spend most of their attention on the shared floors rather than the apartments, which is itself a decision worth reading. A building of 185 homes cannot spread its budget thinly across a thousand residents; it can make a small number of rooms properly good.
Two of the renders answer the question of who the building is for more clearly than any brochure line. There is a children’s play garden at ground level, and a lounge with a dog asleep in it. Sathorn has plenty of buildings sold to people who will never live in them. This one is being drawn for people who will.
Inside the residences
Sizes, layouts and what is actually included.
Read the full explanation
The interior renders show pale timber, veined stone and full-height glass, with the living and dining rooms held in one lateral space rather than divided. Note what is not shown: no floor plans, no room dimensions, and no indication of which of the 39 to 202 square metre homes is being drawn. Treat these as the intended character of the building, not as a specification.
The location
Sathorn, and what that means for a daily commute.
Read the full explanation
Sathon Soi 10 sits in Bang Rak, about 80 metres from BTS Saint Louis on the Silom line and roughly 500 metres from Silom Road. The blocks around it hold the densest concentration of Grade A office space in Bangkok, including Empire Tower, Sathorn Square, AIA Sathorn Tower, Park Silom and Central Park Offices, along with more than ten embassies, BNH and Saint Louis hospitals, and schools including Bangkok Christian College and Assumption College.
That mix is the argument for Sathorn. It is the part of Bangkok where the person who buys the residence is most likely to also work within walking distance of it, which supports both resale and rental in a way a purely residential address does not.
How it reads against the market
Against what else is asking nearby, which is the only comparison worth making.
Read the full explanation
Sathorn has limited new supply and very few sites of this size left, which is the reason a 2,834 square metre plot supports a THB 4.5 billion project. The Monument series has form here: The Monument Thong Lo established the line, and The Monument Sanampao sold out quickly.
The entry price of about THB 9.9 million buys the smallest 39 square metre home. Buyers comparing this against the park-axis corridors should hold the size constant rather than the headline, because a 39 square metre entry at Sathorn and a 57 square metre entry at Dusit Central Park are not the same purchase. Our breakdown of buying costs covers what sits on top of the price in either case.
For a foreign buyer
Tenure, quota and the questions to settle before committing.
Read the full explanation
The project is freehold, so a foreign buyer can own outright within the building’s 49 per cent foreign quota. Funds must be remitted into Thailand in foreign currency so the receiving bank can issue the Foreign Exchange Transaction form used at transfer. What foreigners can and cannot own sets out the rules as they stand.
