Mas del Bot has four double rooms and one superior room. Each has a bathroom, living room and terrace. All the rooms have been built with local straw bales that are supported with wood certified by the Forest Stewardship Council without the use of chemical glue. The straw bales create a natural insulation during all seasons of the year.
The roof of Mas del Bot is unique and natural. It is made of earth and reduces the need for air conditioning during the summer, reducing CO2 emissions. It also contributes to biodiversity, as well as filtering pollutants and CO2 from the air.
The geothermal system is located below ground, and uses the thermal properties of the earth to heat or cool the hotel in a very efficient way. Installing this geothermal system in an ordinary home would save 10 tons of carbon per year, the equivalent of planting 750 trees per year!
The rebound that has been used in the construction is completely natural - a mixture of mud, sand and straw with no chemicals. All the paint that has been used has been made with natural products and without chemicals. The exterior of the hotel has been painted with a mixture of lime, linseed oil and egg white to insulate it from water
