In the picturesque villages of Spain, restored village houses not only reflect cultural traditions, but also set standards for sustainable building and living. Built from regional Mares stone, these houses, which have shaped the landscape for centuries, combine tradition with contemporary comfort. The restoration of these stone houses requires a careful approach, especially in the choice of materials. Mares stone, requires specific care and the use of traditional materials to maintain its quality and functionality. Lime plaster, lime paint and natural insulating materials are decisive factors that are not only aesthetically pleasing, but also contribute to a healthy and stable indoor climate. Refurbishing the old wooden windows is also a key factor in maintaining the indoor climate and natural air exchange. At the same time, modern bathrooms with traditional and contemporary style elements provide a comfortable living experience that is in harmony with the environment. The use of solar panels or photovoltaic systems to power the air conditioning in historic houses can be a sustainable and efficient solution to reduce energy consumption and minimize environmental impact. However, some special considerations must be taken into account in order to preserve the historic character of the building and ensure the best possible performance of the solar system. The careful restoration of village houses is an excellent example of how sustainability and the Mediterranean way of life can merge to create a special living ambience that both honors the past and is future-oriented.
