Neighborhood telecommuting centers (NTCs) are professional workplaces located in residential areas that offer a closer alternative to long-distance commuting. By integrating telecommuting with mobility services, NTCs have the potential to support sustainable travel behaviors, reduce commuting burdens and alleviate space constraints for organizations. This paper adopts a longitudinal, mixed-methods living-lab approach to examine factors influencing NTC use compared to employer offices and home offices. Data from a real-life NTC living lab in Stockholm, Sweden, were analyzed using a three-week time-use diary (27 participants; 572 day-level observations) and panel regression models to identify determinants of workplace choice. Qualitative interviews were used to contextualize inconsistencies between participants' expectations and actual usage. Findings indicate that NTCs can reduce commuting times and provide a professional environment closer to home; however, adoption is constrained by organizational norms, logistical barriers and continued reliance on private cars for trip-chaining. The results suggest that embedding NTCs within mobility-as-a-service (MaaS) like frameworks, through coordinated workplace access, public transport subscriptions and micromobility solutions, while aligning employer policies and institutional practices, is critical for supporting hybrid work models and advancing sustainable urban mobility.
