For the wider area, see [Sukhumvit](https://www.thailandpropertyinvestor.com/areas/bangkok/sukhumvit) and [Thonglor and Ekkamai](https://www.thailandpropertyinvestor.com/areas/bangkok/thonglor-ekkamai).

## A Sansiri and Mitsui Fudosan tower

Sansiri is building XELF with Mitsui Fudosan Asia Development (Thailand), in a joint venture announced in August 2025 at a value of more than THB 5.32 billion. The project is one 37-storey residential tower with a basement and a separate commercial building on about 4 rai. The tower holds 946 homes. The environmental approval and building permit are granted. By 10 November 2026 the work was 13% complete, with completion scheduled for August 2028.

## The homes

There are two kinds of one-bedroom. Lofts of 23.75 to 38.75 sqm put the bed on a mezzanine above a double-height living room. Simplex units of 29 to 35.5 sqm are on one level, with the bedroom behind a door. Together they make up 794 of the 946 homes. A one-bedroom plus of 53.5 sqm adds a multi-purpose room and a second bathroom. Two-bedrooms come as 15 units of 48.25 sqm with one bathroom and 135 units of 55.5 to 56.25 sqm with two. Two three-bedrooms of 85.5 sqm sit on floors 36 and 37. Prices start from a promotional THB 3.59 million.

Facilities include a 30-metre pool with a children's pool and a leisure pool looking over Bang Krachao, a gym with a yoga room, a co-working lounge, a meeting room, a sky lounge and an entertainment room.

## Owning and letting

You hold the unit freehold in your own name, within the 49% foreign quota, with the money sent from abroad in foreign currency. Read [the foreign quota guide](https://www.thailandpropertyinvestor.com/guides/condominium-foreign-quota). Ask us for the payment schedule and the service charges before you reserve. Lets must run for 30 days or more; there is no rental programme. With so many small units in one tower, price your let against the building, not the street. The [rental yield calculator](https://www.thailandpropertyinvestor.com/tools/rental-yield-calculator) shows the return after costs.


## Who it suits

XELF suits a buyer who wants a low entry price close to Thonglor and the Rama 4 offices, either as a weekday base or as a unit to let to a professional on a yearly lease. The lofts suit a single owner who likes height and light. It does not suit a family who need space, or a buyer who wants a quiet building with few tenants. Our [off-plan buying guide](https://www.thailandpropertyinvestor.com/guides/off-plan-buying-process) explains how to judge a build due in 2028.

## Strengths

- BTS Thong Lo is 3 minutes by car and MRT Queen Sirikit Centre 5 minutes, with EmQuartier 5 minutes and One Bangkok 10 minutes, so tenants reach the main office districts quickly.
- The entry price, a promotional THB 3.59 million in November 2026, is low for a Thonglor and Rama 4 address.
- Most homes are one-bedrooms of 23.75 to 38.75 sqm (794 of 946), the size most corporate tenants in Bangkok rent.
- Sansiri, a listed developer, builds XELF with Mitsui Fudosan Asia Development (Thailand), and construction had reached 13% on 10 November 2026 with the environmental approval and building permit granted.
- The 30-metre pool looks over the green belt of Bang Krachao across the river, a rare open outlook for a city tower.

## Considerations

- The tower is not beside a station. BTS Thong Lo is 3 minutes by car or motorbike taxi; walk the route on a viewing before you rely on it.
- With 946 homes, most of them small one-bedrooms, many will be let. Expect a large building with frequent turnover of tenants and more competition when you let your own unit.
- Parking covers about 44% of homes, so not every owner gets a space.
- Completion is scheduled for August 2028. Ask us for the payment schedule, the service charges and the late-delivery terms before you reserve.
- The THB 3.59 million figure is a promotional price and may change. Confirm the price of the specific unit on the day you reserve.
