A modest, customizable structure of rammed-earth, logs, and corrugated metal that can be easily ganged together for multiple-unit communities.


Rammed-earth construction utilizes local materials and labor to construct housing units for individuals and families. Rammed-earth construction uses soil mixed with concrete for the walls and will easily last 50 yrs, per programmatic requirements. Rammed earth technology is thousands of years old and is relatively simple to learn. Floors will be of compressed earth. Forms are re-useable and the cost is spread over multiple units. The roof is corrugated metal, and there is a shaded ceiling of corrugated metal.

A central core supplies power and water to each unit. Shared walls reduce the cost per unit of construction.

Thick walls provide thermal mass for regulating interior air temperature. Personalization of the walls can be done via finish materials and insertion of small objects in the formwork to create relief in the surface, a la the Watts Towers. 

In hot climates, the roofs will be extended to shade more of the structure. In cold climates, the roof overhangs are limited to allow for direct radiation from the sun. 

Units can be joined for families: see the drawing of floor plan options that is included.

The entry doors are on opposite sides to allow for ganging of more units side by side, if desired: see a possible layout drawing that is included.

The proposed system uses a prefabricated extrusion or bent plate at the roof ridge that secures the corrugated metal without holes through the roof. The roof provides rain and sun protection, while the corrugated metal ceiling separates the interior volume from the hot ceiling.

Construction Sequence:

All rammed earth walls are all 8' tall, making construction simple. The ceiling is put in place, then the logs, then the ridge extrusion is attached to the ridge log. Sections of corrugated metal roofing are inserted inside the extrusion and attached at the eave logs, eliminating holes in the roof over the living units.
