The structure has recently received the Architizer A+Awards 2026 Jury Winner in the Spa & Wellness category. IDEE Architects' approach embraces the natural topography of the site. The Hidden Spa - Water Hope complex disappears beneath the dunes with a [continuous curved structure](https://www.trendhunter.com/trends/stealth-1) that follows the existing sand contours. This allows visitors to walk across a planted roof while minimizing visual impact and significantly reducing excavation. At the heart of the project lies a central water courtyard that serves as both spatial and environmental core, with reflecting pools, planted islands, and shaded walkways creating a sequence of spaces where temperature, humidity, and light gradually shift.
