Spherical Skylight Above Sustainable Clay and Straw Residence in Coastal Landscape

Project in-detail

A spherical skylight disperses natural light throughout a residence built from clay and straw, seamlessly integrating with the coastal Gdynia landscape while providing expansive views of the Baltic Sea.
5 key facts about this project
01
A central spherical skylight enhances light distribution in the interior.
02
Rooms are arranged at varying heights for optimal sunlight access.
03
Reflective glass ceilings mimic the movement of ocean waves.
04
Coastal vegetation influences the building's exterior form.
05
Constructed using environmentally friendly materials like clay and straw.

The Shell is a residential project located in Gdynia, Poland, positioned on a cliff that overlooks the Baltic Sea. The design continues the tradition of modernist architecture, aiming to create a strong connection between the home and its natural surroundings. The overall concept revolves around a modified circular shape that enhances views and maximizes sunlight, allowing residents to fully engage with the coastal setting.

Architectural Form

The modified circular layout serves both aesthetic and practical purposes. It provides wide-ranging views of the sea while ensuring ample natural light reaches the interior. The core of the design features a central staircase topped with a spherical skylight, effectively distributing daylight throughout the home. Surrounding rooms are situated at different heights, allowing light to filter in from multiple directions. This arrangement creates a more open and inviting atmosphere.

Light Integration

Effective management of natural light is a vital element of the design. The project includes strategically placed windows and sculpted openings that guide sunlight into the space. Circular skylights built into the roof and ceiling help maintain brightness throughout the home. The ceilings incorporate reflective bumpy glass, which mimics the appearance of ocean waves and enhances the living experience by connecting the interior with the coastal environment.

Sustainable Practices

Sustainability is another important focus of The Shell, illustrated by careful material choices. The use of clay, straw, and wood aims to minimize environmental impacts. These materials contribute to the creation of organic forms, avoiding sharp angles and rigid structures. The design also emphasizes soft edges in the interiors, which help with natural lighting and create a warm atmosphere throughout the home.

Design Detail

Every aspect of The Shell reflects thoughtful design. The combination of light, material, and spatial organization results in a living space that is both practical and appealing. The way shadows shift with the movement of the sun and the reflections from the glass ceilings create a dynamic environment. Each moment spent in the space offers a different experience, underscoring the relationship between the structure and its coastal context.
