Thonglor and Ekkamai suit a buyer who intends to live in Bangkok, or to let to families who do. The two sois, Sukhumvit 55 and 63, form the city's main upper-income residential neighbourhood east of Phrom Phong. Land is priced to match: Thonglor land asked about THB 2.6 million per square wah in October 2025. Prices vary sharply between buildings, so judge value building by building.

What it is like to live in Thonglor and Ekkamai

This is a neighbourhood of side streets. The main sois carry restaurants, cafes, small malls and bars, and the lanes behind them hold low-rise apartment buildings alongside newer towers. The Commons on Thonglor Soi 17 and Donki Mall on Ekkamai Soi 5 are the local meeting points, and Gateway Ekamai sits by the BTS.

Samitivej Sukhumvit Hospital is on Soi 49, at the western edge of the area, which is one reason families settle here. Ekamai International School is in the upper part of Ekkamai, and the larger schools on the Sukhumvit line are a short train ride away: see international schools. The area has a long-established Japanese community, visible in its supermarkets and restaurants.

Property in Thonglor and Ekkamai and what it costs

The stock is condominiums, older and often larger than in lower Sukhumvit, plus a number of high-end towers built over the past fifteen years. A foreigner can own a unit freehold within the building's 49% foreign quota.

Three figures frame the price:

  • Projects launched across Sukhumvit since 2024 average THB 242,130 per sqm (Q1 2026).
  • The average asking price across the central business district was about THB 236,800 per sqm in Q1 2026.
  • In October 2025 Thonglor land asked about THB 2.6 million per square wah, with recent sales reaching THB 2.86 million, and Ekkamai about THB 1.8 million.

New stock in Thonglor is priced at or above the Sukhumvit average, and Ekkamai below it. Start there, then ask for recent transfer prices in the building. Title deeds and due diligence sets out what else to check, and the purchase cost calculator adds the fees.

Who buys in Thonglor and Ekkamai

Buyers are predominantly Thai owner-occupiers, joined by long-term foreign residents. Tenants are typically families and senior staff on corporate leases. Both groups want space, so two and three bedroom units are the heart of this market.

Thonglor and Ekkamai fall within Watthana district, where gross yields in Q3 2026 were 5.19% on two-bedroom units and 4.14% on three-bedroom units, with studios at 5.68% and the largest units at 3.87%. Net figures are usually 1.5 to 2 percentage points lower. Work through your own case with the rental yields guide and rental income and tax.

Getting to and around Thonglor and Ekkamai

Thong Lo and Ekkamai stations are on the BTS Sukhumvit Line. From Thong Lo station, Suvarnabhumi (BKK) is 24 km and about 40 minutes by road. The eastern position helps: the airport is closer from here than from Sathorn or the river.

Inside the area, distance from the station is the main variable. The sois are long, and traffic on them is slow in the evening.

What to watch for in Thonglor and Ekkamai

Value is the main question. Land prices have pushed new launches high, while demand in the upper segment across the central districts has slowed and prices are under pressure. A buyer with cash and patience can negotiate, particularly on completed stock.

Noise is the second. Thonglor's nightlife is part of its appeal and part of its cost. A unit two streets back is a different proposition from one above the main soi.

If a park-side address matters more than restaurants, compare Lumpini and Ploenchit. For the wider picture, see the Bangkok overview.
