The use of conventional technologies in construction has resulted in the industry being responsible for 40% of the global energy consumption and 33% of CO2 emissions. This research aims to evaluate the sustainability of using natural materials as part of an alternative building strategy. The integration of bio-based renewable materials in construction leads to the reduction of the C Footprint and embodied energy of the buildings’ production phase, due to the sequestration of C and the limited processing they undergo. Furthermore, the thermal and hydrothermal properties of plant-based materials make it possible to ensure the occupants’ comfort through passive environmental control. A number of case studies have shown that in urban areas natural materials should be used in conjunction with conventional building materials due to the dimensional constraints of natural structures and the limited availability of raw materials. Due to the accessibility of the techniques, the low cost and short construction time and the low toxicity of the raw materials, the construction of 100% natural buildings is recommended for cases such as development in rural areas as well as part of sustainable development plans in areas of outstanding natural beauty and ecovillages. The case study of Gavdos focuses on accessing the sustainability of building natural constructions in the Natura 2000 area to assist with the islands’ tourist activity management. In order to complete the assessment, the study identifies the drivers that factor into the sustainability of the placement of natural structures in the area and performs a simplified LCA on a proposed dwelling. Finally, alternative design features are compared in order to optimize the thermal performance of the structure. The study aims to prove the feasibility of erecting an autonomous dwelling, within Gavdos’ protected area, with a C negative production stage and limited environmental impact during its life cycle.
