For the duration of 700 years part of the Iberian Peninsula was ruled by Muslims under the name of Al-Andalus. In that period a unique architectural vernacular was established combining the traditional Islamic architecture from cities such as, Damascus, Cairo, and Baghdad, with the locals who have better familiarity with the properties of the land. This combination produced buildings that successfully address the site and its surroundings, and create a healthy, comfortable, and aesthetically unique architecture.

This architectural combination resulted in innovative methods of designing the spatial qualities that was a vast improvement over the architecture of Visigoth. The courtyard of Alhambra is an example of ways to introduce natural light and ventilation, but also give an aesthetic of mysticism and spiritual properties. Meanwhile the Great Mosque of Cordoba show a logical approach of organizing arches that introduces an element of plasticity in space serving the function of the ceremonial rituals.

The architecture Spain from the late 19^th century to the middle of the 20^th have been criticized of being a shallow imitation of the styles that inhabited the region. However the adaptation of elements from the architecture of Andalusia usually resulted on buildings that project a sense of rational values and successful approach to modernity. These examples showcases the understanding of spaces in a functional means.

The research aims to analyze the successful elements in the Moors architecture of spatial qualities, and investigate the methods that architects from the 19^th and 20^th century adapted these elements in their architecture.
