Concept Approach & Architecture Form

Inspired by birds that immigrate to mate or find food, this cabin functions to accommodate workers, students, dreamers, who want to spend just a few days for a good time in the pine forest.

The building form mimics a man-made birds house which is also a very basic & efficient form of human shelter. It's accommodative & anticipative for human needs & natural threats (climate, animals, and bugs). Such forms are acceptable in almost any country & any culture on earth.

The internal space arrangement is separated into 2 (two) areas. First area: thermal lock to reduce heat loss when dwellers are entering the cabin. Second area: the cabin space where dwellers can spend the night with no worries of freezing when the fire is out.

Responding to sloped terrain, jack foundation was chosen to solve the varying landscape & footing needs.


Climate Response


To achieve a winter & summer friendly cabin, the key is insulations & openings. Taking advantage of natural material characteristic for insulation, anti-insect, anti-mold & toxin free is the most ideal green combination. Using 2 layers of insulation for the wall & 1 layer for the roof, is enough to keep the internal space warm. Decreasing internal volume & reasonable ceiling height also plays a role in thermal stability.

The outer Insulation material uses woven straw layer filled witch compacted straw & birch bark as it's anti-insect. The internal insulation material uses a woven straw layer filled with compacted wasted sawn wood & birch bark. There will be a hollow gap in between the insulation as insulator space. All filler of insulation will be treated with anti-bacteria & essential oil made of garlic; celery; turmeric; coriander; betel; basil; sunflower seed etc. Anti-bacteria provided by natural ethanol extracted from aloe Vera; cassia alata L. Birch bark release essential oil when heated which can expel bugs & insect.

Straw & sawn wood can be replaced by grain, oriza sativa, thatch, cornstalk, or any woven able material. Insulation is made up of modular panels. Maximizing the building orientation & opening to south façade to receive maximum benefits of natural light. Wall bottom ventilation in shaded façade lets cool air go through the cabin. Implementing thermal lock room just like man-made birdhouse to keep the warm air inside while entering the cabin as well to restrict cold air from entering.


TRUST US - ITS GREEN

Fast growing wood such as pine wood or softwood is used for the structure. A short module structure using thin & small elements to take ad-vantage of the smallest parts of the tree is useful. These are easier to transport using a small vehicle & will minimize carbon emissions. A photovoltaic panel placed on the roof faces south to maximize sunlight absorption. The energy powers up lights, charges phones, laptops, and a wireless connection to support any research nearby.

In the summer, the wall bottom awning provides cool air that pushes hot air through the upper opening. The ool breeze will likely be enough to cool the interior, considering the summer temperature is only 25°C. The interior finishing uses Oriented Strand Board (one of the lowest carbon emitter materials) that give the impression of being inside a bird nest. The outer finishing uses pine wood skin wasted from structure materials.
