standardized straw-bale load-bearing house
Straw-bale construction is a proven technic (with 200years) I will just highlight some of the benefits; affordable - sustainable -Highly thermal and acoustic insulating - Highly modifiable - No special tools or expertises need (anyone can do it!), and:
All the materials can be outsourced locally
Straw (a sub product of agriculture)
Clay, lime, gypsum (natural)
All the metal parts can be substituted by wood if needed including Roof (just use what the locals use)
More than a house there´s a concept behind the design - Build-it - the constructor/ provider can "just" offer know-how (from assembling procedures to organization/ logistics).
Yet a full kit can be made and sent anywhere.
I porpouse a standardized set of building elements, that should abbreviate construction drastically. (please refer to the pictures)
1. Straw-bale. The bale should be assembled locally meeting the standard dimension. If other dimensions of bales are available the design can be altered to meet this ( software can do this on the fly)
2. one Timber element is used from base to top, again this should be pre-fabricated locally
3. Metal plate. Mass production of this piece should not be difficult and again should be outsourced widin the region. (if all fails it can be substituted by wood using the traditional method of construction)
4. Wood pins (scrap wood, banboo etc)
5. Woodfibre bords. Not an essencial material, is used to cover the floor frame and roof. Depending on the quality of the board (or substitute) can also be used to make shelfs/ beds encastrated on the walls during the building phase.
6 The Lime plaster or clay, should also be made locally, although it can be sent in "just add water" form.
Window/ Door frames folow the same pre-assembled principle. The inside frame, from glass to a mosquito net, should met local requirements.
Roof, corrugated Metal sheets cam be provided. I purpose 2 alternative roof styles, the curved should be adopted when less resources are available and or according to climate requirements.
Additionally there should be provided a metal Stove, water tank w/filter (placed on the roof, the load is welcome), and If possible a solar panel provide further comfort.
Not represented straps to compress the bales during construction and corks to fill the holes not used.
Finally and one of the great benefits of the design: The base model is just the minimum. This model can be connect on both sides, and up (2º floor is possible), Its extendable in all is dimensions and modable to the user needs, by the user himself.

PS: I have used only the components listed on picture 2 to build everything you see (and Sketchup). It would be fun to see the designs you come upon provided this same tools!
