The triangular form of the cabin, clad in mirror solar panels that efficiently harvest energy and rainwater, creates a sustainable living space designed for meditation and self-reflection.
5 key facts about this project
01
The cabin features mirror solar panels that blend into the landscape while generating energy.
02
Rainwater is collected through the exterior skin and filtered for drinking.
03
The design incorporates a triangular floor plan that enhances spatial versatility.
04
A dry toilet system supports ecological hygiene without traditional plumbing.
05
Constructed to leave minimal environmental impact during and after use.

The META Cabin is located in the quiet forest of Ozolini, Latvia. It serves as a simple living space designed for meditation and self-reflection. The overall concept centers on how the building relates to its natural surroundings, using a unique geometric shape to enhance its presence in the landscape.

Geometric Form and Spatial Arrangement
The cabin has a triangular design derived from a rotated cube shape. This interesting form helps to make good use of space inside. The arrangement of rooms is open and adaptable, allowing for a variety of activities. Large windows let in light, connecting the interior with the natural world outside.

Sustainable Systems and Resource Management
At its core, the cabin emphasizes sustainability through smart design choices. Its exterior is covered in solar panels that serve a dual purpose: they generate electricity and collect rainwater. This rainwater is funneled into an internal system that purifies it, making it safe to drink. Such systems reduce reliance on outside resources and minimize the environmental impact.

Health, Sanitation, and Environmental Respect
The design includes a dry toilet that contributes to efficient waste management. This feature reflects an awareness of environmental concerns and practical living needs. Additionally, the construction process ensures that there is little disruption to the natural surroundings, keeping the forest intact and undisturbed.

The light that dances across the mirrored surface of the solar panels adds a distinctive detail to the cabin. This visual effect makes the building feel alive, engaging both those who live within it and the nature that envelops it.
