NovAltitude Development
Altitude Development is better understood as a relatively focused private developer than as one of Thailand's large listed housing groups. Its catalogue spans low- and high-rise condominiums, houses, pool villas and home offices, with much of the activity centred on Bangkok and nearby locations. The company says it was founded in 2014 by Chayaphon Hunrungroj and Kwanchai Yingchareonthawornchai. For a buyer, the brand name is only the starting point: Altitude's own project pages identify several different legal entities as the developer or project company.
A company name is not a recommendation. Check the project company, contract and selected unit before reservation.
Overview
Altitude Development is better understood as a relatively focused private developer than as one of Thailand's large listed housing groups. Its catalogue spans low- and high-rise condominiums, houses, pool villas and home offices, with much of the activity centred on Bangkok and nearby locations. The company says it was founded in 2014 by Chayaphon Hunrungroj and Kwanchai Yingchareonthawornchai. For a buyer, the brand name is only the starting point: Altitude's own project pages identify several different legal entities as the developer or project company.
Track record
The company's own project records provide several concrete reference points. Altitude Prove Rama 9 is described as a home-office development built from 2017 to 2019. Altitude Symphony Charoenkrung is listed as a 22-storey condominium built from 2019 to 2021. Altitude Unicorn Sathorn-ThaPhra, completed in 2022 after a 2019 start, contains 711 residential units and names Altitude Creed Talat Phlu Co., Ltd. as developer. One Altitude Charoenkrung is an 85-unit condominium with a stated 2021–2025 construction period, while its project company is One Altitude Development Co., Ltd. The record demonstrates completed development activity, but it also makes project-level entity checks essential.
Segments and prices
Altitude's live website spans several price points rather than one clearly defined bracket. At the time of review it advertised Altitude Symphony Charoenkrung from THB 7.9 million, One Altitude from THB 12.9 million and The One Bellagio from THB 49 million. Its house section also retains sold-out listings such as Altitude Mastery Phahonyothin 24 from THB 34.5 million and Altitude Mastery Sukhumvit from THB 35 million. These are developer-published asking or promotional figures, not a guaranteed current price range. Availability, incentives, furnishing and transfer-related costs should be confirmed for the exact unit.
Geography
Bangkok is the core market, with projects shown across Charoenkrung, Samyan, Talat Phlu, Rama 9, Bangna, Phahonyothin and other parts of the metropolitan area. The official catalogue also extends beyond the capital: Asa Ayutthaya–Rojana is listed in Ayutthaya, while The One Bellagio is in Salaya, Nakhon Pathom. The practical implication is that the Altitude name does not create one uniform market profile; rental demand, transport access and resale depth need to be assessed at the individual location.
Reliability and public record
Altitude has a larger public-document trail than many private developers because it has issued debt securities. In 2023 the Thai SEC registered a secured debenture offering of up to THB 450 million carrying a 7.5% coupon and an original maturity date of 1 September 2025. There are also material caution points in the regulatory record. The SEC crowdfunding disclosure page lists several Altitude debt-default notices in December 2024 and January 2025; one report dated 2 January 2025 recorded THB 1 million of overdue principal on crowdfunding issue No. 4, originally due on 25 December 2024. Separately, on 18 February 2026 the SEC reported a THB 79,800 settlement fine against Altitude for filing its 2023 annual financial statements and key financial ratios late. None of these events proves that every residential project is distressed, but they materially raise the importance of checking the current finances and funding of the exact project company. The SEC publication page reviewed in July 2026 displayed audited 2023 accounts and reviewed first-half 2024 statements, so a buyer considering a current transaction should request fresher financial evidence rather than rely on brand history alone.
What to verify
The first Altitude-specific check is the contracting entity. Official project pages variously name Altitude Development Co., Ltd., One Altitude Development Co., Ltd., Altitude Creed Talat Phlu Co., Ltd., Alternative Asset Co., Ltd. and The Royal Gems Golf And Sport Club as developer, so the relationship between the marketed brand and the actual seller should be documented rather than assumed. For an off-plan property, ask for land-title evidence, the construction permit, environmental approval where applicable, an updated build schedule, project-funding evidence and the contractual remedy for a material delay. Given the debt-default notices in the regulatory record, current financial information for the exact contracting entity and the destination of buyer payments deserve particular attention. For a completed condominium, a foreign buyer should also confirm foreign-quota availability, inspect the actual unit and common areas, check outstanding juristic-person charges and obtain a complete transfer-cost statement.

Frequently asked questions
Is Altitude Development listed on the Stock Exchange of Thailand?
No. Altitude Development Co., Ltd. is a private company rather than a SET-listed property developer. Some of its financial and corporate disclosures are nevertheless available through the Thai SEC because the company issued debt securities.
Is Altitude Development Co., Ltd. always the legal developer behind an Altitude-branded project?
No. Altitude's own pages name One Altitude Development Co., Ltd. for One Altitude, Altitude Creed Talat Phlu Co., Ltd. for Altitude Unicorn Sathorn-ThaPhra and Alternative Asset Co., Ltd. for Altitude Define. The legal seller therefore needs to be checked project by project.
Has Altitude had publicly reported debt defaults?
Yes. The Thai SEC published several notices concerning defaults on Altitude crowdfunding debt issues in December 2024 and January 2025. That should not be treated as proof that every development is affected, but it is a material reason to examine current project-company finances and funding before committing to a purchase.
What price range does Altitude currently advertise?
There is no single price tier. At the time of review the website showed Altitude Symphony Charoenkrung from THB 7.9 million, One Altitude from THB 12.9 million and The One Bellagio from THB 49 million. These are advertised starting prices, not confirmation that a specific unit remains available at that figure.
