Teknion | Introducing WithIn™, a new special capability from Teknion Architectural Interiors. Make a Space Within Your Space. Designed for a more adaptable and agile workplace, WithIn™ is a simple post-and-beam structure that defines an interior space. WithIn subdivides the open plan into different zones, creating areas in which people can work as a group or personal spaces that serve a more intensive focus. WithIn creates an independent framework for both permanent and transitional spaces, allowing companies to readily adjust to new work behaviors and patterns.
