A helical canopy crafted from marine-grade steel and translucent glass rises above a circular atrium, seamlessly integrating renewable energy and local flora to create a sustainable floating hotel experience.
5 key facts about this project
01
Helical canopy design captures rainwater while providing solar energy.
02
Circular atrium enhances natural light and guest interaction with the ocean.
03
Marine-grade steel ensures durability in salty marine environments.
04
Integrated green facades promote local biodiversity and environmental adaptation.
05
Direct water access facilitates unique aquatic experiences for guests.

### Overview
The Eco-Floating Hotel is proposed for a coastal location, prioritizing sustainable design while providing luxury accommodations. The project seeks to harmonize the built environment with its marine surroundings, thereby addressing ecological challenges inherent in coastal hospitality developments.

### Spatial Strategy and User Experience
The architectural layout features a circular design centered around an atrium, topped with a helical canopy that collects rainwater. This arrangement ensures stability by anchoring to the seabed, while the smooth curves evoke the contours of marine life, promoting tranquility. Guests have direct access to various aquatic amenities, such as water terraces and infinity pools, which facilitate engagement with the natural environment.

### Material Selection and Sustainability
The Eco-Floating Hotel employs a carefully curated selection of materials that enhance both aesthetic quality and environmental performance. Reinforced concrete underpins the structure for durability, while extensive glazing maximizes natural light and seafront views. The integration of solar panels not only supports energy needs but also aligns with the project’s goal of achieving net-zero energy consumption. Additionally, sustainable timber and marine-grade stainless steel are utilized, with green facades featuring native plants contributing to biodiversity and environmental resilience.
