STILL Sukhumvit 20 is a 30-floor tower of 124 residences on Sukhumvit Soi 20, developed by SC Asset jointly with Tokyo Tatemono, the Japanese developer’s seventh project with SC per its own release of 26 November 2025. Construction runs from April 2026 to a scheduled completion of September 2028. With so few homes across thirty floors, a private lift serving each unit and ceilings up to 3.5 metres, the building reads as low-density rather than dense, and the development value is about 6 billion baht. The mix, per the developer’s own page: two-bedrooms of 85 to 124 square metres, three-bedrooms of 134 to 218, corner suites of 217 to 235, junior penthouses of 163 to 321, and one 439 square metre penthouse.

The building is freehold, which confers outright ownership that passes to heirs rather than a lease that has to be renewed. Foreign buyers can hold freehold units within the foreign quota, which Thai law sets at 49 percent of a building's total saleable floor area, and Embark confirms a unit's quota status at inquiry.

Common questions

Is STILL Sukhumvit 20 freehold or leasehold?

It is freehold, which confers outright ownership that passes to heirs rather than a lease that has to be renewed. Foreign buyers can hold freehold units within the foreign quota, which Thai law sets at 49 percent of a building's total saleable floor area, and Embark confirms a unit's quota status at inquiry.

Who is the developer?

STILL Sukhumvit 20 is developed by SC Asset, a Thai listed developer, jointly with Tokyo Tatemono, the Japanese developer whose own release of 26 November 2025 records this as its seventh joint project with SC. International sales run through All Well Corp, named by SC Asset as its exclusive international sales partner in writing on 29 November 2025; Embark advises buyers through that channel as part of our coverage of the Sukhumvit corridor.

When will it complete, and how big is it?

STILL Sukhumvit 20 is a 30-floor tower of 124 residences, with construction from April 2026 and completion scheduled for September 2028, per the joint developer Tokyo Tatemono’s own release. Each unit is served by a private lift with ceilings up to 3.5 metres, and homes run from two-bedrooms of 85 square metres to a 439 square metre penthouse.

How much does STILL Sukhumvit 20 cost?

SC Asset’s own page lists pricing from THB 45.1 million as of September 2026, and Thai property press reported the project over 60 per cent sold at its launch weekend of 7 and 8 February 2026. The remaining developer stock we track sits in the foreign quota. We hold the developer’s current price list and confirm unit-by-unit pricing and quota status privately, at inquiry, because the list is the developer’s to publish, not ours.

Where we stand

What we cover. Branded residences and individual luxury units across the Lumphini park-axis, Sukhumvit corridor, and Riverside.

How we work. Principal-led. A small number of buyers at any given time. A short call first; viewings only after priorities are clear.

What we avoid. High-volume listings, sales pressure, and pushing a unit when another residence fits the buyer better.
