### Architectural Design Report: Courtyard House

#### Project Overview
Courtyard House is a contemporary residence situated in an urban setting that emphasizes Arab heritage through the incorporation of a central courtyard. This design fosters social interaction and community engagement, drawing inspiration from traditional architectural concepts while integrating modern sustainability practices.

#### Spatial Organization and Layout
The design framework is based on a modular system comprising two distinct units: a base module of 2.4m by 20m and a larger module of 4.2m by 12m. This configuration allows for flexibility in accommodation, with essential service areas such as kitchens and bathrooms occupying the base module, while living and social spaces are arranged in the larger unit. The three-dimensional organization spans two to three floors, enabling various configurations to support different family dynamics.

Public and private areas are thoughtfully delineated, with communal spaces oriented towards the central courtyard for optimal daylight access. The ground floor features main entrances leading to shared living areas, while upper floors provide personal rooms designed for privacy and interaction balance. This arrangement facilitates family gatherings and cultural events while allowing for individual seclusion.

#### Material Strategy and Sustainability
The choice of materials reflects both environmental considerations and local aesthetics. Structural elements utilize a concrete composition integrating lime and ash to reduce carbon emissions. Finishes include an orange-hued, earth-based plaster enhancing thermal comfort while resonating with regional design traditions.

Sustainability is further realized through the integration of a green roof planted with native vegetation and photovoltaic panels to meet energy needs. Natural ventilation is achieved with operable windows and strategic orientation to enhance airflow and minimize reliance on mechanical cooling systems. This holistic approach to materiality not only supports ecological sustainability but also reinforces the project's connection to its cultural and environmental context.

The architectural features signify a blend of angular and geometric forms, highlighted by arched openings that echo traditional motifs. The color palette, inspired by the surrounding desert landscape, provides visual continuity with the environment, promoting a sense of place.
