Architectural design is the art and science of planning and designing buildings and spaces. It is not limited to just the external aesthetic form; it also includes the study of function, durability, safety, and the distribution of interior spaces in a way that serves the needs of users and harmonizes with the surrounding environment.

The architect: focuses on the overall structure of the building, the exterior facades, the distribution of essential spaces, obtaining permits, and ensuring the structural safety of the building and its compliance with regulations.

The interior designer: intervenes after or during the architectural design phase to focus on the interior spaces, lighting distribution, selection of materials and colors, and furniture arrangement to make the space comfortable, functional, and attractive.

The architectural design goes through several main stages, which are:

Initial Concept: Understanding the client's needs and defining the basic idea.

Schematic Design: Creating preliminary plans that illustrate the distribution of spaces.

Design Development: Specifying materials, facades, and detailed elements.

Construction Documents: Preparing precise engineering drawings for the contractor to begin construction.

There is no fixed price, as the cost depends on several factors including: the size of the project, the level of complexity, the experience of the engineering office, and the location of the project. The cost may be calculated as a percentage of the total construction cost, as a fixed fee per square meter, or based on hours worked.

There are many styles, the most famous of which currently are:

Modern: Focuses on clean lines, glass, and avoiding excessive ornamentation.

Contemporary: Combines several modern styles and emphasizes sustainability and innovation.

Classical: Characterized by symmetry, columns, and luxurious decorations.

Islamic: Relies on arches, domes, and geometric or floral decorations, providing privacy.
