What is the Allen curve?
The Allen Curve, a theory coined by Professor Thomas J. Allen of the Massachusetts Institute of Technology (MIT) in the 1970s, examines the relationship between physical proximity and the frequency of interactions among individuals within an organizational environment. The Allen Curve graphically represents the exponential decrease in communication frequency between individuals as the distance between them increases. This concept has had significant influence in many areas, such as commercial building design and project management.
The Origins of the Allen Curve
During the late 1970s, Professor Allen undertook a project to determine how the distance between engineers’ offices influenced the frequency of technical communications among them. The result of this research produced what is now known as Allen’s Curve. The curve reveals a strong negative correlation between physical distance and the frequency of communication between workstations. In other words, the closer engineers are physically, the more frequently they communicate with each other. However, when the distance exceeds a critical threshold of 50 meters, the frequency of communication decreases significantly.

Meaning and Applications of the Allen Curve
With a broad understanding of the importance of communication for innovation, the Allen Curve is frequently taught and cited in management literature on innovation. This principle has had a significant impact in many fields, as the design of commercial architectures (for example, the Decker Engineering Building in New York, the Steelcase Corporate Development Center in Michigan, the BMW Research Center in Munich, and the Volkswagen assembly and delivery center in Dresden), as well as the management of projects. In summary, the Allen Curve reminds us that physical proximity among people can foster effective communication and innovation within an organization.
Recently, with the rapid advancement of the Internet and the reduction in telecommunications costs, some scholars have recently questioned how to apply the Allen Curve in the business environment and have noted that the effects of communication frequency based on distance remain valid: for example, a 1986 study on emails and a 1989 research on the frequency of communication between “geographically dispersed computer manufacturer websites” confirmed the trend towards a decrease in the use of all means of communication with distance. Furthermore, physical proximity continues to influence communication, as the more often we see someone in person, the higher the likelihood of communicating through other means such as phone or other platforms.

The Allen Curve in the offices and workspaces
Surely, the Allen Curve has important implications for office work.
Here are some key takeaways:
1. Smart Working & Proximity: although only 6.3% of the respondents work entirely remotely, while the 51.2% work remotely for 2-3 days a week, those who practice partial smart working show a significant increase in satisfaction with their work-life balance, performance, and work situation overall. Physical proximity influences the frequency of interactions and the perception of work well-being.
2. Balance between pros and cons: despite the benefits of remote work, there are sources of stress and dissatisfaction related to it. For example, 47.8% of respondents believe that remote work has a negative impact on their relationship with colleagues, isolating them. Moreover, 69.7% associate smart working with a worsening of their work situation, although it does not influence performance. These disadvantages are particularly significant for those over the age of 45.
3.Time and Stress Management: 52% of Italians see smart working as a way to eliminate commuting costs between home and work, thus reducing stress and improving time management. This advantage is emphasized by audiences with more experience and older age.
How to apply the Allen Curve to the office of the future?
The office of the future will be smarter and shaped by considering various trends, including many technological aspects of Industry 4.0. After the pandemic and the increase in the practice of remote working, employers are reconsidering how much and what type of office space they will maintain, and how to ensure that the new work environment is equally healthy, attractive and stimulating.
The Allen Curve can be applied to the office of the future in multiple ways. First and foremost, it can guide the design of workspace. For example, it can suggest the creation of more shared areas or “neighborhoods” where multiple colleagues can work together flexibly. This could foster communication and collaboration among team members, in line with the findings of the Allen Curve.
Furthermore, the Allen Curve can influence how organizations manage remote work: although digital technologies have made it possible to work from anywhere, the Allen Curve suggests that physical proximity can still play an important role in facilitating communication and collaboration.
The Allen Curve and performing workspaces according to Stella33
The Allen Curve provides valuable insights into how physical proximity influences communication and collaboration: as organizations design the office of the future, taking these insights into account can help create work environments that foster innovation and productivity.
The goal pursued with Palazzo Isola Nova, however, it doesn’t just offer a space where business can thrive — along with well-being of its users — but also aims to be that of transforming the location into a hub that provides space for the community. This entails triggering a a novel mechanism for activating business relationships (which is also unheard of in a traditional office context). While physical proximity enhances the levels and quality of communication, as suggested by Professor Allen, space can become a true catalyst for a network of relationships and thus business opportunities, bringing together people from different sectors and triggering a fruitful flow of know-how.
The Stella33 Team believes that the evolution of the office is moving increasingly towards agile solutions, marked by innovation, collaboration, well-being, and creativity. But above all, every company is different, and to create offices that are true destinations, it’s necessary to always take these differences into account in the design of the spaces: this is why Stella33 creates personalized and bespoke spaces, because one fits one.
