As employees are a significant expenditure for companies, human-centric design and workplace optimization is gaining ground. WHO reported that the costs incurred on the global economy because of depression and anxiety was estimated as 1- trillion US dollars per-annum in lost productivity in 2019. This lost in cost and productivity can be considered as waste which can be eliminated by using Lean construction to optimize the workplace environment. Therefore, the main research question here was to know that to what extent the IEQ parameters and Managerial Environment, relate to mental wellbeing while working at corporate office spaces. Employees of diverse scale firms of Ahmedabad were considered. A mixed-research methodology was being adopted and data was collected by means of a questionnaire survey and interviews.
