A finely constructed house or building hides the vast majority of its inner parts. Like the skin on a body, typically either a drywall or plaster are constructed to conceal a complex web of plumbing pipes and joints, electrical wiring and outlets.
Such concealment is not always common today. The ceiling components in many new stores and restaurants – once discreetly hidden by a drop-ceiling grid containing 2’ x 4’ panels – now reveal a run of girders, PVC pipes and smartly painted ductwork for the HVAC system.
