**1. Modern Building Facade Design:**
In the design of modern building facades, features such as clean and rare lines, the use of modern materials like glass and concrete, flexibility in forms and various geometric shapes are observed. Windows and lighting are used as important elements in the exterior view to establish better connections with the surrounding environment. Horizontal and vertical lines are employed to create balance and movement in the facade. In these designs, simple colors and harmonious combinations are chosen according to the architectural context.
**2. Building Floor Plan Design:**
In building floor plan design (طراحی پلان ساختمان), aspects such as proper space allocation, optimized flow of movement within the building, connections between rooms and spaces, efficient use of light and ventilation, and establishing a connection with the external environment are considered. Modern design principles emphasize on space recycling, eliminating unnecessary walls, and utilizing open and curtain spaces. Open floor plans, alternative layouts (non-centralized), and the use of perpendicular flows (vertical and horizontal) are among the characteristics of this design approach.
**3. Villa Design:**
In villa design, comfort, luxury, and connection to the natural environment are of paramount importance. Creating beautiful views from both inside and outside the villa, designing open and covered spaces for various activities, using high-quality materials, and appropriate interior design to create a sense of tranquility and well-being for residents are significant. Modern villas typically have large windows, open floor plans, spatial connections, and meticulously designed gardens.
In conclusion, facade, floor plan, and villa design depend on factors such as the desired architectural style, functional requirements, surrounding environment, and materials used. Each of these aspects should be in harmony to create an appealing, practical, and contextually fitting architectural design.
