What Is Gray Shell/ Cold Shell?
A Gray Shell or Cold Shell refers to a partially completed building that includes the exterior envelope (such as walls, roof, and windows) but lacks interior finishes, fixtures, and systems. This state of construction allows for future interior build-out and customization by tenants or owners, providing a flexible space that can be adapted to specific needs.
