Want to benefit the environment and save money on a comfortable abode? Consider what the company Conceptos Plásticos (Plastic Concepts) is capable of accomplishing in just five days. 

Founded in 2011 by Colombian Fernando Llanos and architect Óscar Méndez, Conceptos Plásticos specializes in creating affordable, eco-friendly houses in a short period of time. In fact, its iconic 2 bedroom/1 bathroom house can be constructed in just five days with a team of four workers.

Ordinary-looking at first glance, the 430 square foot structure is made from recycled plastic bricks that snap together like Legos. It cost only 20,000 pesos ($6,800) to make and is able to resist combustion, provide insulation and meet local earthquake-resistance requirements.
