Hallthat

Hallthat is a term used in architectural and urban design discourse to denote a flexible, multipurpose transition space adjacent to a primary hall. In this usage, hallthat combines circulation with programmatic functionality, allowing a single area to forgo a single fixed purpose in favor of adaptable social, educational, or display activities. The term signals a shift from conventional, separate uses for corridors, lobbies, and galleries toward a blended space that can host people as they move through a building as well as events that happen within it.

Etymology and scope: The coinage appears to blend hall with that, emphasizing the space’s ability to perform “hall-like” functions while also embracing additional roles. The concept is not standardized and may be defined differently by designers, institutions, or planning documents.

Design characteristics: Hallthat spaces typically feature open plans, modular furniture, transparent or low partitions, and adaptable lighting. They favor clear sightlines, acoustic zoning to separate quiet circulation from louder activities, and accessible routes that connect principal entries with interior programs. The aim is to support wayfinding, safety, and flexible programming, including receptions, informal gatherings, or temporary displays.

Context and usage: The idea has appeared in critiques and proposals for modern museums, university campuses, and civic centers, where a single adaptable zone can serve as ceremonial entry, casual lounge, and gallery-like corridor depending on need. It is most effective when its boundaries between public and private functions are deliberately designed and managed.
