Good buildings are not created by accident. They are carefully planned, starting with how people move inside them. When circulation is poorly designed, it can cause crowding, discomfort, and confusion. This task will be eased with the help of an architectural circulation diagram, which is a simple visualisation showing how people move through a building. It is often used during the design stage or after construction to verify how well the layout works.
Read this blog to learn about circulation in a building, the definition of a circulation diagram, the different types of circulation diagrams, the major elements included in a circulation diagram, design principles, and additional related topics.
What is Circulation in Architecture?
In architecture and interior design, circulation illustrates the movement patterns and flow of people through a building or space. These pathways represent the routes taken within a floor plan. Good circulation makes movement simple and systematic, while poor circulation can affect the overall space functions.
What are Architectural Circulation Diagrams?
Building circulation diagrams are sketches or graphics showing the movement patterns within a structure’s space. This will provide a brief idea of how people can move throughout a building, using arrows, lines, and shapes to represent circulation routes. These circular diagrams will be drawn for both residential and commercial buildings, showing the overall accessibility and functionality of the space.
A circulation diagram indicates movement paths on the floor plan, unlike a floor plan that only shows the physical layout of rooms, walls, and spaces. It commonly includes space routes, such as corridors, pathways, staircases, elevators, and other means that help people to flow and reach different areas of a building.
Why Is Circulation Critical in Building Design?
During the design phase of a building, both architect and engineer need to consider the circulation so that they can:
- Map and evaluate the movement of people around the building spaces.
- Recognise potential issues, such as bottlenecks or inefficient movements, and design the space to be more comfortable for easy movement.
- Carefully design the room to facilitate effective movement and circulation in both public and private areas, and place entry/exit points accordingly.
- Create well-designed circulation patterns that help prevent congestion, especially during emergency situations.
- Ensure occupants experience a sense of comfort while moving through the space, which positively influences well-being and productivity.
Types of Circulation in Architecture
The following are the major types of circulation in architecture:
Horizontal Circulation Architecture
In this type of circulation, people will use the horizontal walkways for the flow and movement. It can include corridors, passages, lobbies, doorways, entrance foyers, and balconies. This circulation type is often used in homes, apartments, offices, and schools for easy movement between rooms and zones.
Vertical Circulation Architecture
In this vertical type of circulation, people will use vertical ways to move between a building’s different levels and floors. It can include stairways, ramps, elevators, and escalators that are built in all multi-floor buildings for easy access between two floors.
Circulation Spaces in Residential vs Commercial Buildings
| Residential Buildings | Commercial Buildings | |
| Design Focus | Mainly focused on privacy, comfort, and supporting the daily activities of residents. | Focuses on wayfinding, accessibility, and managing large numbers of people. |
| Circulation Pattern | Movement should feel natural and easy. | Movement needs to be clear, planned, and well organised. |
| Wayfinding | Residents are familiar with the space, so even without wayfinding, movement between rooms remains smooth and confusion-free. | Most building users may be visitors or employees who are unfamiliar with the space, so wayfinding is essential. Signage, colour coding, open layouts, and good visibility help people easily navigate. |
Key Elements and Proven Techniques for Effective Circulation Diagrams
To prepare an effective architectural circulation diagram, the architect/design engineer needs to understand both visual aspects and the functionality of the movement within the structure.
The following are the major elements and techniques that architects and design engineers use to enhance the circulation diagram:
- Visible Representation of Pathways: To easily distinguish the routes, the primary path for movement will be shown by using bold lines and secondary routes with dashed lines or lines of lighter thickness in a circulation architecture diagram.
- Spatial Connections: Design engineers clearly indicate how different spaces connect to each other. They make use of colour coding or different line thicknesses to highlight links between entrances, exits, and important functional areas.
- Pause Areas: Design engineers mark places where people usually gather or where their movement speed reduces, such as waiting areas or seating zones. Simple icons or clear markings will be used to help identify these spots.
- User Movement Types: Design engineers show separate paths for different users, like pedestrians and vehicles. This helps explain how various users navigate the space in other ways.
- Legends and Notes: Design engineers add a clear legend to explain symbols, colours, and line types. Short notes can also be included to give extra clarity where needed.
Key Principles of Good Architectural Circulation Diagram Design
The following are circulation design principles used to create a good circulation design in architecture:
Clear and Intuitive Movement: Circulation design should feel natural and easy to follow. Strategic entrance placement helps guide sightlines and encourages instinctive movement. Good circulation reflects natural human behaviour, such as choosing the most direct and visible route, and supports smooth navigation through spatial cues and visual connections.
Minimum Travel Distance: Efficient circulation reduces unnecessary movement within a space. Concepts like the working triangle in kitchens, offices, and clinics help balance function in compact areas by minimising travel between frequently used zones. This improves usability and saves time.
Logical Zoning: Proper zoning ensures that related spaces connect smoothly while maintaining order and privacy. Circulation paths should clearly link entrances, functional areas, and exits without overlap or confusion. Logical zoning supports rhythm and flow within the layout, improving overall spatial efficiency.
Accessibility and Universal Design: Circulation spaces must be designed in accordance with applicable building codes, ensuring safety and legal compliance. Corridor widths should allow comfortable movement and legal clearance, typically ranging from 1.2 to 1.8 metres in commercial buildings. Designing for all users, including people with mobility issues, children, and the elderly, is a basic requirement.
Natural Light and Ventilation in Circulation Spaces: Well-designed circulation areas enhance user experience beyond movement alone. Access to natural light and ventilation contributes to comfort, emotional well-being, and spatial memory. Thoughtful circulation design can create calm transitions or energising movement through space.
Common Circulation Planning Mistakes to Avoid
The following are the common circulation planning mistakes in a building:
- Narrow corridors can make the movement difficult and create bottlenecks, reducing comfort and safety.
- Dead-end circulation confines access and emergency exits, reducing overall building efficiency.
- If the staircase placement is not in the proper position, it can disturb flow and accessibility, especially in multi-storey buildings.
- Mixing public and private movement paths compromises privacy and security, affecting occupant experience.
