Constructed with black lava sand and enveloped by a living plant epidermis, the retreat harmonizes with its thermal waters while offering spaces for communal engagement and personal reflection.
5 key facts about this project
01
The structure incorporates black lava sand concrete to blend with the volcanic landscape.
02
A living plant epidermis is used to enhance environmental integration and seasonal change.
03
Thermal waters are visually accessible from the central gathering area.
04
Footbridges connect various pavilions, promoting circulation and interaction.
05
Design elements reflect the cultural narrative of the hidden people of the land.

The design presents a thoughtful blend of built structures and the natural landscape, located in a remote area that highlights a connection to elemental themes. The concept centers around the notion of a “ship” anchoring itself to the ground, promoting a relationship between the architecture and the environment. This space serves as a refuge for travelers, encouraging both social interaction and opportunities for personal contemplation.

Conceptual Framework

The idea of the “hidden people” is an essential theme, drawing from cultural narratives that highlight the significance of indigenous inhabitants. This approach reflects an understanding of ecological balance and a desire to harmonize with the surrounding ecosystem. The arrangement of spaces balances private areas and communal ones, allowing users to engage deeply with the architecture and the natural environment.

Spatial Configuration

Users enter through a space referred to as the “Earth’s concavity,” which leads to a welcoming central foyer. Here, elements like dancing flames create a warm atmosphere. This area encourages social gatherings while maintaining views of the nearby thermal waters. Throughout the site, footbridges and pavilions serve specific purposes, including wellness activities and social gatherings, helping users navigate the various areas of the design efficiently.

Material Considerations

The materials chosen for construction are vital to achieving the overall vision. Black lava sand concrete makes up the base, connecting the structure to its rugged surroundings. The use of manufactured panels forms the main structural framework, providing both stability and versatility. Concrete panels act as protective layers, complemented by a textured white finishing plaster that harmonizes with the landscape. Additionally, the inclusion of a plant epidermis hints at an ongoing interaction between the architecture and nature, creating an evolving surface that changes with the seasons.

Spaces invite users to find peace among the elements, with design details that enhance the overall experience. Light and shadow play together, creating a dynamic environment that encourages reflection and deeper connections with the world outside.
