Design, Hospitality and Construction
The design draws on Thai and Japanese basketry, with landscaped terraces introducing greenery into the tower. Thai Obayashi also plans to use LRV construction technology, preparing components before on-site assembly to improve construction control and reduce site activity. Project announcement.
The hotel is being developed through a partnership between Thai Obayashi and Saha Group. SPI's earlier announcement describes a garden-inspired hotel with dining, meeting and wellness facilities, under a management agreement with Seibu Prince Hotels Worldwide. Source: Saha Pathana Inter-Holding.
What This Means for Residential Buyers
For MCLL ASIA, the residential relevance is in the surrounding neighbourhood. The planned combination of workplaces, hospitality and shops gives buyers another development to consider when comparing homes around Ratchadamri and the wider Langsuan-Lumphini area.
Assess each residence on its own merits: walking routes, construction exposure, outlook, management and ownership terms. A nearby commercial project alone does not establish a property's future rental demand or resale value.
