What is shell construction?

Shell construction refers to the phase of building where the structural framework or 'shell' of a building is constructed. This includes the foundation, walls, floors, and roof, but typically excludes interior finishes, plumbing, electrical, and HVAC systems. Shell construction provides the essential support and weatherproofing for a building, serving as the basic structural envelope. It is a crucial stage because it establishes the building's size, shape, and overall strength, laying the groundwork for subsequent interior work.
