White Box service, also referred to as "vanilla shell," "grey shell," "core and shell," or "base building," refers to providing property owners a space that is partially finished or equipped with basic utilities and infrastructure. The term "warm lit" implies that the space has functional lighting, heating, ventilation, and other essential systems in place. However, it may not have fully finished interiors, such as walls, flooring, or specific tenant improvements. Warm lit shell service offers tenants the convenience of moving into a space with essential utilities already in operation while allowing them flexibility to customize and complete the space according to their specific needs and requirements.
