An office wall unit is an ideal storage center that basically sits against a wall without taking too much space. To make your own office wall unit measure the area as per your design. Take careful measurements of the length, height, width and depth of all shelves and the structure as a whole. Determine whether you want sliding or opening doors for the same before you buy the wood.
Select the wood of your choice or opt for timber wood as it gives the look of wood for a reasonably lesser price. Work to a plan and cut and sand all shelves and unit pieces before fixing them according to the measurements.
Once the framework has been done affix it to the intended wall and continue to attach shelves, doors, knobs and handles. Sand, dust and smoothen all surfaces and finish off with a stain or varnish of your choice.
