How to Build a Countertop Shelf

Sketch your project on paper, approximately to scale. The shelving unit will have two vertical panels and top and bottom shelves. It may also have additional shelves between them. Include in the sketch the dimensions of the vertical panels, shelves and spaces between the shelves.

Lay the lumber on a flat surface. Refer to the dimensions on your sketch to measure the length of a side panel on the plank. Use a carpenter’s square to draw a horizontal line across the plank to form a cutting line. Trim the plank there. Measure, mark and cut a second side panel to the same dimensions.

Refer to the dimensions on your sketch to measure, mark and cut the horizontal planks that will form the shelves. They must all have the same dimensions to join properly. Use sandpaper to remove any splintered areas on the ends of the boards before you assemble the shelf unit.

Turn the marked boards on edge so the marked surfaces face each other. Position a shelf plank between the boards. Align the edges of the shelf with the corresponding lines on the side panels. Nail the side panel to the shelf while keeping the edge of the shelf aligned to the mark on the side panel. The nails should be no more than 2 inches apart. Nail the opposite end of the shelf to the opposite side panel. Continue positioning and attaching the shelves to the sides of the unit until they are all securely attached.

Lay the shelving unit on a flat surface so the edges of the shelves and the edges of the side planks are facing upward. Place an L-shaped bracket on each outer joint where the ends of the shelves meet the sides of the shelving unit. Screw one leg of the bracket to the side panel of the shelving unit. Use a carpenter’s square to square the joint. Screw the unattached leg of the bracket to the edge of the shelf. Repeat to square and attach brackets to the three remaining outer joints.
