Citi Smart Sukhumvit 18

The address used consistently in recent market listings is 366 Soi Sukhumvit 18, Khlong Toei, Khlong Toei, Bangkok 10110. ThinkOfLiving publishes coordinates at 13.735018, 100.562226. The building sits inside the soi rather than directly on Sukhumvit Road, with BTS Asok and MRT Sukhumvit reachable on foot. Different portals quote slightly different walking distances, so a precise minute count is less reliable than the broader point: this is a genuinely transit-oriented central location. For residents who work around Asoke, Phrom Phong, Ploenchit or connected BTS/MRT districts, daily transport can be straightforward without a car. The trade-off is the nature of the area itself — dense, active and urban rather than quiet or resort-like.

Scale is one of the project’s more distinctive features compared with many later Asoke towers. The strongest public record supports 192 units in a single building. Floor count is less tidy. The Bangkok municipal study and Nishimatsu’s project record both say 20 floors, while DDproperty, PropertyScout, ThinkOfLiving and several broker databases describe 21 floors. We retain 20 floors in the registry because the municipal and contractor sources carry more weight, while flagging the conflict rather than pretending it does not exist. The discrepancy is unlikely to change a purchase decision by itself, but it is a useful reminder that even basic specifications for older buildings should be checked against building and unit documents when they become transaction-critical.

As of early September 2026, resale asking prices span a wide range. PropertyHub showed a two-bedroom unit around 75 sqm at THB 10M, while other current two-bedroom listings of roughly 72–88 sqm were asking about THB 10.3M–13.5M. Three-bedroom stock is much broader: a roughly 123 sqm unit was marketed at THB 16M, while a large 240 sqm upper-floor residence was offered at THB 42M. These figures should not be read as a price list. Renovation quality, floor, outlook, tenancy status, layout and ownership position can all materially affect an asking price. The THB 10M figure is therefore used only as a lower market entry point visible in current listings, not as a valuation for the project as a whole.

The live resale and rental market also gives a clearer picture of the unit mix than generic project pages. Studios and one-bedroom units around 40 sqm appear in current rental stock. Two-bedroom units commonly show up around 70–88 sqm. Three-bedroom apartments range from roughly 114–123 sqm for more conventional family layouts to much larger 173–240 sqm homes, including upper-floor units. Older directories list studio through three-bedroom formats, but we do not treat marketplace examples as an official original schedule of areas. Units in a twenty-year-old building may have been reconfigured or combined, and portal data can be inconsistent. For any purchase, the title deed and registered unit plan are the right sources for the exact area and configuration.

Amenities reported across the main project directories include a swimming pool, fitness room, sauna, parking, security and CCTV; some databases also mention a garden and children’s area. For an established building, the list itself tells only half the story. The more useful question is how those facilities and the core building systems are performing today. A viewing should include the lifts, corridors, pool deck, gym, parking and visible service areas, not just the apartment. It is also sensible to review condominium juristic-person information on maintenance, major repairs and reserves where available. An older central project can offer larger floor plans and a proven location, but deferred common-area work can become a meaningful ownership cost.

For a foreign buyer, Citi Smart Sukhumvit 18 is best understood as an existing freehold condominium building where unit-level eligibility still matters. DDproperty and PropertyScout describe the project tenure as freehold. Thai law nevertheless limits aggregate foreign freehold ownership to 49% of the total unit area in a registered condominium building. The selected unit therefore needs a quota check before transfer, together with the seller’s title and the condominium juristic person’s required certificates. This is one of the advantages of buying resale in a functioning building: the physical asset, its management and the exact apartment are all inspectable. The purchase decision should rest on those verifiable details rather than on a general assumption that every unit in a freehold condominium can automatically be registered to a foreign buyer.
