Abstract: A case has a main body with a plan storage compartment for holding a set of construction plans and one or more accessory storage boxes. A lid is hinged to the main body and is movable between a closed position to cover and protect the set of plans in the plan storage compartment, and an open position to allow viewing of the plans. Binder clips at opposite ends of the plan storage compartment secure the set of plans in place and a strap on the underside of the lid holds turned pages of the plans when the lid is open, thereby permitting individual pages of the plans to be easily viewed while the entire set of plans is secured in place and held open to a selected page. A recessed area on the underside of the main body accommodates folding leg members which are operable between a collapsed position, in concealed relation within the recessed area, and an extended position to support the case in a horizontal, elevated position above the floor, forming a table.
