The Tiny Sea House is located in Playa del Carmen, Mexico, a growing coastal city that faces challenges from both tourism and environmental changes. The design addresses two main issues: the spread of sargasso seaweed, which impacts local ecosystems, and the rising demand for housing due to an increasing population. The concept emphasizes sustainability and flexibility, creating a compact living space that is responsive to both the environment and its residents' needs.

Materials

The structure makes extensive use of sargasso seaweed, which is transformed into stable bricks for construction. This approach not only solves the problem of excess seaweed but also supports the local environment. The design also incorporates Chukum, a natural soil material commonly used in the region. This choice ties the building to local practices while reducing its ecological footprint.

Spatial Configuration

The layout features an efficient use of space, with two fixed modules designated for essential functions, such as the kitchen and bathroom. The living area includes a versatile furniture module equipped with sliding rails, allowing residents to rearrange the space as needed. This flexibility enables the house to adapt to different lifestyles, making the most of its compact size.

Environmental Considerations

The design includes an urban garden integrated into the ceiling, which serves multiple purposes. It allows residents to grow their own fruits and vegetables, promoting self-sufficiency. Additionally, the garden helps to maintain a comfortable indoor climate. A corridor runs along the perimeter of the house, acting as a thermal buffer that improves energy efficiency.

Natural Light and Space

Natural light plays a significant role in the overall design, thanks to the arrangement of the sargasso bricks. These bricks allow sunlight to enter the living spaces, creating a warm and welcoming atmosphere. By focusing on light and spatial design, the Tiny Sea House offers a pleasant environment for its occupants.

The attention to detail in the Tiny Sea House reflects a balance of modern living and ecological awareness. Its innovative features and sustainable practices create a living space that is both functional and harmonious with the surrounding environment.
