Earthships are sustainable, self-sufficient housing designed to minimize their environmental impact. The concept was developed by architect Michael Reynolds in the 1970s, with the aim of creating housing that uses natural resources efficiently and is independent of traditional public service networks.

These houses are generally built with recycled and local materials, such as used tires, cans, glass bottles and compacted earth, forming thick walls that provide thermal insulation and thermal mass. The design incorporates passive heating and cooling systems, such as strategic solar orientation and natural ventilation.

Additionally, earthships often include systems for capturing and using rainwater, treating greywater for reuse, and generating renewable energy, such as solar panels and wind turbines. These characteristics make earthships an attractive option for those looking to live sustainably and reduce their environmental footprint
