## Nang Linchi, the residential side of Sathon

WIDEN by Sansiri stands on Nang Linchi Road in Thung Maha Mek, Sathon district, a residential quarter of low-rise blocks and houses south of the [Sathorn and Silom](https://www.thailandpropertyinvestor.com/areas/bangkok/sathorn-silom) office towers. Market Place Nang Linchi and Villa Market are 100 metres away, Raintree International School 450 metres, St Andrews International School, Sathorn, 2.1 km and BNH Hospital 2 km. One Bangkok is 2.7 km away. There is no rail station on the road: BTS Chong Nonsi and MRT Lumphini are each about 7 minutes by car off-peak.

## The development

Sansiri, a developer listed on the Stock Exchange of Thailand, builds WIDEN with Tokyu as its joint-venture partner. One 34-storey tower of 215 homes stands on about 2 rai, with parking for about 105% of homes. Construction began in July 2025 and was 26% complete on 10 November 2026, with completion scheduled for February 2028.

## The homes

The mix leans to larger homes. One-bedrooms are 45.25 sqm with a separate kitchen. Two-bedrooms run from 63.75 to 90.75 sqm, and a two-bedroom plus of 88.5 sqm adds a multi-purpose room. Three-bedrooms of 143.75 sqm on floors 21 to 29 have a living terrace and a powder room. On floors 31 to 33, three sky residences of 186.5 to 209.75 sqm add a maid's room and a Thai kitchen. Prices start from THB 8.59 million and reach THB 49.9 million.

Facilities include a 25-metre infinity pool facing the Bang Krachao river bend, a garden with a putting green, a pet playground, a fitness suite with sauna and steam rooms, a sky lounge, a co-working space and a rooftop garden.

## Owning and letting

You hold the unit freehold in your own name within the 49% foreign quota, paying from abroad in foreign currency. Read [the foreign quota guide](https://www.thailandpropertyinvestor.com/guides/condominium-foreign-quota) and [sending money to Thailand](https://www.thailandpropertyinvestor.com/guides/sending-money-to-thailand). Ask us for the payment schedule and the service charges before you reserve. There is no rental programme: lets must run for 30 days or more. The [rental yield calculator](https://www.thailandpropertyinvestor.com/tools/rental-yield-calculator) shows what a yearly let returns after costs.


## Who it suits

WIDEN suits a family that wants space, parking and an international school within walking distance, a short drive from the Sathorn offices. The sky residences suit a household that would otherwise rent a house. It suits less well a buyer who wants to walk to the BTS every day; for that, compare [The Monument Sathon](https://www.thailandpropertyinvestor.com/developments/the-monument-sathon) on Sathorn Soi 10.

## Strengths

- Parking covers about 105% of homes, so a family can expect a space for each home, which is rare in central Bangkok towers.
- The unit mix leans to family sizes, with two-bedroom plus, three-bedroom and sky residence plans up to 209.75 sqm.
- Raintree International School is 450 metres away and St Andrews International School, Sathorn, 2.1 km.
- Construction started in July 2025 and stood at 26% on 10 November 2026, so the building is well under way.
- Sansiri is a listed developer with completed Bangkok towers to inspect.

## Considerations

- There is no BTS or MRT station on Nang Linchi Road. BTS Chong Nonsi and MRT Lumphini are each about 6 to 7 minutes by car off-peak, longer at rush hour.
- Completion is expected in February 2028. Until then your money is committed and the home earns nothing.
- Ask us for the payment schedule and the service charges, with the delivery terms of the contract, before you reserve. We send them in writing.
- The developer projects a rental yield of 5% to 7% for the area; this is a projection, not a guarantee. Model your income on a lower figure and test it with the rental yield calculator on a yearly let.
- The land and building are mortgaged to Kasikorn Bank during construction, which is normal for a Thai project. We confirm how your unit is released from the mortgage at transfer.

## Rental
