Concrete Grease Trap and Reed Bed System in Immersive Nature Retreat

Project in-detail

Incorporating a concrete grease trap and a reed bed for greywater purification, the design immerses visitors in the serene forest environment while providing a focused space for wellness and relaxation.
5 key facts about this project
01
Each sleeping pod features a direct connection to the natural surroundings through an open shower.
02
The design incorporates a sustainable greywater purification system utilizing a reed bed.
03
Sound insulation is prioritized to enhance the auditory experience within the pods.
04
Concrete grease traps manage waste water effectively while minimizing environmental impact.
05
Capsules are strategically oriented to provide unique views of the forest landscape.

Cápsula is located in the remote forests of central Portugal, designed to provide a peaceful escape for visitors at the Vale de Moses Yoga retreat. The concept focuses on creating a strong connection between people and nature, encouraging immersion in the environment. Each sleeping pod serves as a space for rest and reflection, engaging the senses of sound, smell, and sight for a more profound experience.

Architectural Layout

The structure is organized around a central circulation pathway that divides public and private spaces. This pathway runs through four quadrants, promoting ease of movement and accessibility throughout the area. The sleeping capsules are positioned to offer unique views of the surrounding forest, enhancing the feeling of being immersed in nature and encouraging tranquility.

Acoustic Considerations

Sound is a crucial element of Cápsula's design. Each pod is crafted to enhance natural sounds while providing necessary insulation. This thoughtful acoustic design fosters a calm atmosphere that supports relaxation and meditation. Inside the pods, materials are arranged to reflect and absorb sound effectively, creating an environment that promotes mental well-being.

Sustainable Features

Cápsula incorporates a natural greywater purification system, highlighting its commitment to sustainability. Greywater from washing facilities flows into a concrete grease trap, where larger solids are filtered out. It then moves through a baffle filtration system for further cleaning. The water eventually reaches a reed bed, where wetland plants help purify it before it is stored for reuse.

Lighting Integration

The lighting design in Cápsula is primarily powered by photovoltaic panels placed on the pitched roof. This system offers flexibility, enabling the illumination of individual sleeping pods or shared areas. It creates a cozy and inviting atmosphere while maintaining alignment with the project’s sustainability goals. The connection between light and space enhances the overall experience, merging indoor living with outdoor beauty.

A notable design feature is the open shower facility that connects the interior of each pod with the natural environment, allowing users to engage with the outdoors in a direct and refreshing manner.
