$300 dwelling for the poor
My inspiration is in the smart usage of plastic bottles and How-To make a decent house with all materials that is already used or can be found in nature, to built dwelling for the poor people.

Solution

Construction is made of reused wood beams connected together with ropes, nails or wires; 

Insulation, walls, doors  and "windows" are made with plastic bottles;
Flooring is made of reused wood palettes, tiles, glass jars or wood tiles.
Mortar can be applied on the walls, or fill bottles with the adobe but it is up to locals.
Roof is corrugated for the practical reason to store bottles that are in solar disinfection process.

Drinking water is made with procedure called Solar disinfection in plastic bottles on the corrugated steel roof.

Rainwater harvesting  is planned in from the roof to the cistern, plastic buried in ground and in the deep waterproof stone well.
