STILL Sukhumvit 20

Privacy is built into the physical plan. Every residence is advertised with private lift access, while a 24-hour concierge is part of the service model. Tokyo Tatemono’s project release also describes ceiling heights of up to 3.5 metres in the residences. The absence of small one-bedroom stock reinforces the same idea: these homes are intended to function as long-stay residences, with enough room for children, guests, home working or live-in support depending on the layout. The project is also pet-friendly and includes a dedicated pet yard. Pet owners should still ask for the final house rules before buying, because a pet-friendly building can impose limits on size, number, access routes and use of shared areas.

The amenity plan is spread through several levels instead of relying on a single pool-and-gym deck. The ground floor is planned with the main foyer, living room, conservatory, business lounge, pet yard and Collector’s Garden. The eighth floor is a quieter retreat level with a lounge, spa, onsen, playroom, dressing room, dining lounge, grill yard and terrace. Floors 26 and 27 contain the principal health club facilities: a poolside lounge, main pool, children’s pool, thermal pool, home gym, Pilates and yoga studio, movie room and golf room. This breadth is valuable to a resident who will actually use the building as an extension of the home, but it also helps explain why the common-area charge is not a trivial line item.

September 2028 is the delivery target supported by the strongest project evidence. Tokyo Tatemono announced a planned construction start in April 2026 and scheduled completion in September 2028. Syntec, the named construction contractor, separately lists its work period from 16 August 2026 to 30 September 2028. Those dates can coexist because a development programme and an individual contractor’s scope do not have to start on the same day. As of 29 August 2026, the appropriate status is under construction. Anyone who needs a finished Bangkok residence in the short term should treat the 2028 handover as a hard practical constraint rather than a footnote.

SC Asset is the consumer-facing developer brand, while the development structure includes Tokyo Tatemono (Thailand), the local subsidiary of Tokyo Tatemono, as a joint-development participant. Tokyo Tatemono describes STILL Sukhumvit 20 as its seventh joint project with SC Asset. Syntec’s project page names SC CD5 Company Limited as the project owner. That distinction matters at contract stage: a familiar development brand does not necessarily mean the same legal entity will appear as seller, owner or payment recipient. Buyers should match the legal name, project documents and payment instructions in the reservation and sale documentation before funds move.

Published ownership costs are specific enough to budget around without inventing totals. The common-area management fee is THB 150 per sq.m per month and the sinking fund is THB 1,200 per sq.m as a one-time charge at transfer. We do not multiply those rates into unit-specific totals because the correct number should follow the contracted area of the selected residence. Parking is conventional rather than automated, but the public figures are not fully aligned: one project channel states 175% parking while a joint-development release gives 216 spaces, equal to 170% of the residential unit count. Until the final specification is checked, the exact ratio should not be treated as fixed.

Pricing is the other area where a buyer should separate a market anchor from a developer quote. Late-August 2026 market listings include two-bedroom stock around THB 30M, while SC Asset’s current project page displays a starting figure of THB 45.1M. Those numbers can refer to different unit pools, older allocations or different commercial conditions, so they should not be compared as though they were the same apartment. For this dossier, THB 30M is used only as the lower observable market reference. The exact unit number, floor, view, foreign quota status, specification and payment schedule need to be confirmed together before the price means anything.
