How to Build a Dual Workstation L-Shaped Computer Desk

Measure the longest wall in the room. Divide the wall measurement in half and mark the wall. Move a stud finder along the wall in the area where you want to install one leg of the dual workstation desktop. Mark the location of each stud.

Position a file cabinet measuring 28 inches tall at the end of the wall-mounted section of the workstation. Position a second cabinet facing away from the first cabinet and parallel with the wall. This cabinet is for the person working at the peninsula side of the workstation. Place a third cabinet facing the same direction as the second cabinet at least 48 inches from the side of the second cabinet. This will support the outer leg of the workstation.

Measure from the inside wall of the first cabinet to the back of the second cabinet. Cut a piece of 2-by-2-inch board to this length using a table saw.

Place the board on the wall between the two cabinets and even with the top of both cabinets. Position a level on the top of the board. Draw a straight, level line between the cabinets. Screw the board to the wall using the line as a guide. Screw two long wood screws through the board and into each wall stud using a power screwdriver.

Purchase two pieces of laminate countertop pre-cut with a 45-degree mitered corner at the lengths you require. Select the style with no backsplash attached. Place the counters on the cabinets and align the miter to make sure the sections are the correct size. Move the counters so you have access to the underside of the mitered corners.

Place plastic sheeting on the floor under the mitered corners. Insert the countertop spline into the horizontal slot along one inside edge of the mitered cut. Press it in firmly. Apply wood glue to both inside edges of the mitered corner cut and the spline. Move the sections together so that the spline slides into the companion slot and the sections are aligned.

Attach the miter bolt into the closest recessed morticed notch. Use a wrench to tighten the bolt. Attach all of the remaining miter bolts in the same manner. Your seam may have three to five morticed notches for miter bolts. Tighten the bolts evenly to draw the seam together firmly.

Stand up and run your finger along the seam. If one side is higher than the other is, place a small block of wood on the seam; then tap down with a hammer until the seams are smooth and even. Tighten your miter bolts slightly. Wipe off the excess glue with a water-moistened rag. Dry the seam immediately so that no water penetrates the seam. Allow the glue to cure for 24 hours.

Slide your counter into position. If your cabinets are not level, use wood shims underneath the base to level them. Remove your counter. Apply a glob of silicone adhesive to each top corner area of each cabinet. Apply adhesive along the top edge of the 2-by-2-inch board. Lift your counter and set it in position, tight against the wall and attached to the cabinets.

Screw through the underside of the board into the underside of the counter along the wall. The screws should be short enough that they do not penetrate through the top of the counter. Screw every 12 inches. Measure, cut and iron a laminate end-piece on the outside edge of the counter.
