Designing an architectural project involves a significant amount of intricate detail.
Every step of a project is meticulously planned to ensure both safety and day-to-day comfort. This careful coordination of safety and comfort is referred to as flow.
Architectural design is a conceptual discipline that focuses on the individual components or elements of a structure.
Generally, an architect is the professional in charge of the architectural design.
Architects work specifically with space and various elements to produce a structure that is both coherent and functional.

An architectural drawing is a technical representation of a building or a building project.
These drawings serve four primary purposes:
- Developing a design idea into a coherent and structured proposal.
- Communicating specific ideas and concepts to stakeholders.
- Enabling the actual construction by providing necessary details to a building contractor.
- Creating a permanent record of an existing building for future reference.
These drawings are primarily created using CAD (computer-aided design) software.

Concept Drawing: These are utilized by architects and interior designers as a quick and simple method for exploring initial design ideas during the early stages of a project.
Site Drawing (Site Plan): A site plan is a detailed engineering drawing. It provides essential information regarding:
- Grading and topography.
- Landscaping details.
- Building arrangement on the property.
- Other infrastructure or land-specific details.
Structural Drawing: This type of drawing serves as a plan for how a building will be physically constructed. These drawings focus specifically on the load-carrying members of a structure to ensure stability.

A floor plan is a technical drawing representing a room, residence, or commercial building (such as a restaurant or office).
Representation and Scope:
- These plans can be represented in either $2D$ or $3D$ .
- They showcase the spatial relationship between rooms and spaces.
- They depict the placement of internal elements such as windows, doors, and furniture.
Importance:
- Floor plans are critical for the success of any architectural project.
- Architects, engineers, and builders utilize specialized floor plan software to generate high-quality plans for upcoming projects.
Information Provided:
- A floor plan offers a preview of the finished architectural project.
- It illustrates how the overall space is divided.
- It indicates specific dimensions and measurements for elements including windows and doors.
Utility for Project Progression:
- Stakeholders use the floor plan to suggest changes before moving into specialized technical stages, which include:
- Electrical layouts.
- Plumbing systems.
- Structural engineering details.
- Landscaping design.

Technical Floor Plan: These offer highly specific details and measurements. They focus on the relationships between rooms and spaces within a building engineering project. They are strictly drawn to scale and typically represent only $1$ level of a structure per drawing.
3D Floor Plan: This provides a view of the architectural space in three dimensions. Utilizing a $3D$ view allows for a much better understanding of the size, layout, and physical proportions of the space.
Humanized Floor Plan: These are more realistic than other plan types and are ideal for presentation settings. In architectural and building engineering contexts, they illustrate how an environment will appear once the space is fully completed. This includes the representation of furniture, sinks, and other domestic or commercial objects.

The design process consists of several distinct stages, each vital to the project's aesthetics, feel, and safety.

In this initial phase, the architect gathers information regarding the client's needs, style, and desires for the project.
The architect creates $2$ to $3$ design options for the client to review.
Within CAD applications at this stage, hatch and pattern fills can be placed with a single pick.

The architect takes the schematic designs and refines them into a single, approved design concept.
This is the critical phase for client communication; any changes the client wants to make to the design must be communicated to the architect during this time.

The architect compiles drawings with an immense amount of detail for the building contractor to follow during the construction phase.
These documents are the primary instruction set for building the project.

This stage involves the architect or client seeking a contractor to execute the build.
The job is "bid" to contractors using bid documents. These documents include the detailed construction drawings and technical specifications of the project.

This phase begins once a preferred contractor is found and a design concept that fits all needs has been finalized.
The architect remains in contact with the contractor throughout the entire duration of this phase to ensure the project is constructed strictly according to the plans.

Class Exercise: Given the information provided on architectural design and building models, students are expected to discuss and attempt to identify specific architectural elements within an architectural drawing or a building model.
