Build two additional shelves that are slightly wider than the previous ones. These will form the center section of the entire storage unit. Each wider shelf will use one 64-inch board in the middle and one 67-inch board on each side. Follow the same assembly process as before: lay out the boards on a flat surface, ensure correct crown orientation, clamp, pre-drill, and secure with 2.5-inch deck screws.
Goal: Assemble two wider shelf frames to be used as center connecting shelves.
This DIY project provides detailed instructions for building heavy-duty, space-saving wooden shelves in a garage, specifically designed to fit into narrow spaces while still allowing a car to be parked and its doors to open comfortably. The shelves are constructed from 2x4 lumber and are built to be sturdy enough to hold various items like oil, cleaning supplies, plastic boxes, and tools.
Sketch out a design for your shelving unit. Decide on the type of shelves (fixed or adjustable), the spacing between them (consider the items you plan to store), and the overall structural support needed. You can opt for a simple bookcase style or a more complex, custom-built unit that follows the angle of the stairs. Consider whether the back of the unit will be open or against the wall.
Design and construct open shelving or a bookcase unit to fit within the under-stair space, maximizing storage and aesthetic appeal.
