Resident experience

5 of 6 buildings rated · scale 1–10

AI research over published reviews and resident comments. Scores are a model’s reading of opinion, not figures stated on a page, and nothing here feeds any number above it. The links under each block are the pages that research says it used. Based on available resident reviews of covered buildings. These are reported experiences, not independent building inspections, and may not represent all residents or properties.

Upkeep and response — belongs to whoever runs the building now. From 5 of 5 rated buildings here and 53 in the market.
The market here is Thailand: every other developer whose head office is in the same country, because the review platforms residents use, and the service norms they judge against, move together within one. It is not a city, a sector or a price band. Read structure and living together. A developer above the market on structure and below it on living builds well and runs buildings badly, which is a fixable problem and a different one from building badly. Higher ratings are better; differences use the displayed scores rounded to one decimal. Rated buildings only, on both sides, and a structure or living score with no stated basis — no review count and no notes or links — is left out of both.

Risks & source coverage

  • REGULATORY May 31, 2023 (reported June 1, 2023) On May 31, 2023, Thailand’s Central Administrative Court revoked the EIA approval for Supalai Loft Ratchada–Wong Sawang after finding the EIA approval process unlawful and inadequate in assessing impacts on neighbours’ sunlight and wind; Supalai said construction had to be temporarily suspended, that it would appeal, and that it had contacted customers with proposed solutions, while the retrieved evidence does not establish the final appeal outcome by October 12, 2026.
  • LEGAL August 28, 2024 (reported September 4, 2024) On August 28, 2024, the Bangkok South Civil Court ordered Supalai to pay 6,208,000 baht plus 5% interest to 12 Supalai Bella Wongwaen–Rama 2 consumers and remedy flooding, finding that homes and site levels were built below the approved plans and that delivery did not comply with the sale and land-allocation requirements; the consumer council’s report states the court found no clear intent to exploit consumers and therefore imposed no punitive damages.
  • RISK November 4, 2021 (published November 5, 2021) On November 4, 2021, Thailand’s Consumer Council reported a complaint concerning Supalai Riva Grand in which Supalai allegedly insisted on forfeiting 473,200 baht in reservation, deposit and down-payment instalments after a buyer’s mortgage was rejected; the council said only qualifying earnest money could be forfeited and that the other amounts should be returned, but the retrieved page does not establish a final court or regulator resolution.

Click a row in the chart to open a project, or a table row below to see its sources. The chart runs wider than the page where the record spans many years — scroll it sideways to follow a project to its handover. Every date we have is drawn. A hollow marker is only a launch year, not a date anyone published. No dates published means we looked and found none; dates not yet checked means we have not looked yet. Handing over is not finished — rows say which. A delay is shown when one source gives the promised date and another gives the real one, however rough: "2019" still counts, and the row shows how wide that is. Projects missing one of the two dates, or with sources that disagree, are left out of the figures. 4 dated statements are held back: a broker listing with no date on it, or a page with no year, cannot fix a date. 1 turned out to be about something else — a phase, a neighbour, the wider masterplan — and is marked off-subject.

Supalai Premier Samsen-RatchawatDusit, Bangkok248 units
9.6/ 10
—/ 10
9.6/ 10

Google Reviews/Maps supplies the largest and only identified building-specific aggregate: 4.7/5 from 33 reviews, converting to 9.1 under the stated curve. The visible excerpts are strongly positive about amenities, views, security and location, so commentary adds about 0.5; no structural score is assigned because the published material contains no actual structural or systems condition evidence.

+ Rooftop pool and fitness facilities+ Pleasant atmosphere and views+ Convenient location+ Security praised+ Nearby market and transport
− Noise mentioned

no notes returned

no links returned

Published Google excerpts describe the daily experience positively: residents/reviewers mention “วิวสูงสบายตา” (pleasing high views), a pool, fitness room and common lounge, and another says “ระบบความปลอดภัยสูง” (high security). The main operational caveat is noise—one 5/5 excerpt says “เสียงดังบ้าง” (somewhat noisy)—and a separate review complains that a charging space is occupied without being used.

Supalai Blue Whale Hua HinHua Hin523 units
9.4/ 10
—/ 10
9.4/ 10

The Google Reviews/Maps aggregate of 4.7/5 from 29 reviews is the only qualifying published building rating located and therefore sets the level; the stated conversion curve gives 9.1/10 before commentary. Repeated praise concerns facilities, presentation and views, supporting a modest upward adjustment, while the lone promotional-noise complaint is minor and not recurring.

+ Extensive facilities+ Rooftop sea and mountain views+ Attractive building presentation+ Positive sales-staff feedback+ Good-looking condos
− Promotional-truck noise

no notes returned

no links returned

The published reviews describe strong day-to-day appeal: one reviewer praised the staff and "very beautiful condominium with all the infrastructures," while another highlighted the pool, gym, hotel-like entrance, three lifts and rooftop rooms with sea and mountain views. The main negative was a 1/5 complaint that promotional trucks and jingles made the area feel noisy; this is a single minor complaint, not a recurring management failure.

Supalai Kram Khao TaoHua Hin84 units
7.9/ 10
—/ 10
6.5/ 10

Google Reviews/Maps supplies the only published building-specific aggregate found: 5/5 from 3 reviews, which converts to 10 before the low-review-base constraint. Because the anchor has fewer than 10 reviews, the score is kept within one point of 6.5; no recurring complaint or praise theme was established from the material read.

+ Energy-efficiency certification reported for all four buildings+ Inverter air-conditioning and LED lighting described+ Energy-saving glazing and lightweight concrete wall materials described
+ Pool+ Fitness facilities+ 24-hour security+ CCTV+ Quiet/private setting near the beach and reservoir

No resident review located reported leaks, plumbing, HVAC, lift or other physical failures. A 10 October 2026 report says all four buildings received the No. 5 energy-efficiency label and describes inverter air-conditioning, LED lighting, energy-saving glazing and lightweight concrete walls; this is published project/award material, not resident maintenance feedback.

The only visible written review was positive: “โครงการใหม่ใกล้ทะเลแวะชมได้ครับ” (“New project near the sea; come visit”), rated 5/5. Project descriptions report a pool, fitness facilities, tropical garden/lounge and 24-hour security/CCTV, while an August 2026 report characterizes the setting as quiet and private; these amenity claims are not a substitute for a larger resident-review record.

Supalai Sense SrinakarinBangkok477 units
7.9/ 10
—/ 10
7.5/ 10

The Google place listing reports the largest and only located aggregate for this specific project: 4.8/5 from 6 reviews. Its unconstrained conversion would be high, but because the anchor has fewer than 10 reviews the rules require keeping the score within one point of 6.5; no recurring complaint or praise theme was established to move it further. The result is therefore a cautious 7.5/10, with structure left unscored because no resident structural rating was published.

+ 10-year structural warranty+ 3-year fittings warranty+ completed and ready to move in
+ resort-style common areas+ 36-metre swimming pool and jacuzzi+ fitness and co-working space+ shuttle service to MRT+ 24-hour security and CCTV

No resident-reported structural or systems failures were found in the published material reviewed. Supalai’s 2024 report states that Supalai Sense Srinakarin provides a “10-year structural warranty and 3-year fittings warranty”; independent project reviews describe the project as completed and ready for occupancy, but these are not resident condition ratings.

The only visible user review says “Great beginning,” while the published project reviews emphasize a resort-style concept and facilities including a pool, jacuzzi, fitness room, co-working space and rooftop garden. They also describe shuttle service and 24-hour security/CCTV, but there is not enough resident-written evidence to establish management speed, staff attitude or recurring operational problems.

Supalai Icon SathonSathon, Bangkok720 units
7.7/ 10
—/ 10
7.7/ 10

Google Reviews/Maps supplies the only qualifying building-level aggregate found: 4.3/5 from 86 reviews, which converts to approximately 7.9/10 under the specified curve and sets the anchor. The reported repeated noise complaint moves the result down modestly to 7.7; no structure score is assigned because no qualifying structural/system rating was published.

− Poor sound insulation
+ Modern and clean+ Secure+ Good location+ Large amenities+ Cinema praised
− Parking system criticized− Traffic-line system confusing− Noise complaints

The published resident/visitor comments contain a repeated acoustic complaint: one reviewer wrote, “Bad Bad sounds insulation,” citing hallway and construction noise, and another reported repeated late-night disturbance. No published review evidence located here establishes a failure of the framework, plumbing, HVAC, electrical systems, lifts, or waterproofing.

Daily-life feedback is mixed. One review calls the property “Modern. Clean. Secure” and another says it has “The best cinema we've been to,” while a separate reviewer says the parking system is “very bad” and the traffic-line system confusing; other reviews complain about hallway, construction, and late-night noise.

Only buildings that have reached handover are rated. 1 of 6 projects carries no rating: a building still under construction is never asked about, one that has just been handed over may not have been reached yet, and the rest were asked about and no published resident commentary was found. Structure is fixed at handover and stays the developer's; management and living belongs to whoever runs the building now. The overall verdict weights both rather than averaging them. None of this is checked: a rating is what people published about a building, aggregated — it is not evidence, it cannot move a delay figure, and it is not part of the delivery record above.

Projects

Assessment coverage

Completed projects: 2016-10-15 through 2026-10-15. Initial research is capped at 10 completed projects and a separate delivery-risk search capped at 7 findings. Risk findings are not project assessment counts. Absence is not proof of a complete portfolio or no failures. Month-level dates overlapping a boundary are excluded from figures.

2 undated completions and 1 boundary-uncertain completions are retained but excluded from figures.

Stalled, cancelled & overdue projects

0 evidenced cases
The capped delivery-risk search ran; no project-level exception cases are recorded here. Risk findings are listed under Risks and are separate from assessed projects. This does not establish that the developer has no delivery failures.

5 found
REGULATORY May 31, 2023 (reported June 1, 2023)
On May 31, 2023, Thailand’s Central Administrative Court revoked the EIA approval for Supalai Loft Ratchada–Wong Sawang after finding the EIA approval process unlawful and inadequate in assessing impacts on neighbours’ sunlight and wind; Supalai said construction had to be temporarily suspended, that it would appeal, and that it had contacted customers with proposed solutions, while the retrieved evidence does not establish the final appeal outcome by October 12, 2026.
LEGAL August 28, 2024 (reported September 4, 2024)
On August 28, 2024, the Bangkok South Civil Court ordered Supalai to pay 6,208,000 baht plus 5% interest to 12 Supalai Bella Wongwaen–Rama 2 consumers and remedy flooding, finding that homes and site levels were built below the approved plans and that delivery did not comply with the sale and land-allocation requirements; the consumer council’s report states the court found no clear intent to exploit consumers and therefore imposed no punitive damages.
RISK November 4, 2021 (published November 5, 2021)
On November 4, 2021, Thailand’s Consumer Council reported a complaint concerning Supalai Riva Grand in which Supalai allegedly insisted on forfeiting 473,200 baht in reservation, deposit and down-payment instalments after a buyer’s mortgage was rejected; the council said only qualifying earnest money could be forfeited and that the other amounts should be returned, but the retrieved page does not establish a final court or regulator resolution.
DELIVERY DELAY 31 May 2023 event; 29 March 2024 status report; 25 March 2025 company ESG publication; research position 12 October 2026
Supalai Public Company Limited’s Supalai Loft Ratchada–Wong Sawang was ordered to suspend construction after the Central Administrative Court revoked its EIA on 31 May 2023; Supalai said it would appeal and, as reported in March 2024, the matter remained before the Supreme Administrative Court with unused tower cranes removed. A later property-listing claim says the project was completed in December 2024, but the retrieved company ESG disclosure (published 25 March 2025) still describes the suspension as continuing pending the Supreme Administrative Court, so the ultimate status is uncertain rather than treated as an active failure as of 12 October 2026.
RISK 28 August 2024 judgment; 4 September 2024 publication; company disclosure published 25 March 2025
Supalai Public Company Limited was ordered by the Bangkok South Civil Court to pay ฿6,208,000 plus interest to 12 homeowners in Supalai Bella Wongwaen–Rama 2 after findings that homes and site levels did not conform to approved plans and contracts, causing defects, subsidence and flooding; Supalai’s 2024 ESG disclosure said remediation remained in progress, including drainage-gate and pump improvements.
