Have you considered the fact that maximizing your vertical space, makes more efficient your cost of your business overhead...why is that you say? Understanding what vertical space is and how you can expand it makes you a much better steward of your fixed overhead.

Most of us think in terms of the square footage we are leasing as an 'unchangeable fixed cost'  but in the world of space planning, getting more office in the same space is simply good management of our fixed costs....most of us think in terms of the space that a conventional desk takes up or that a credenza uses and can't be enhanced or improved but using our available 'vertical space' is very wise and stretches our dollars.  Visualize each square foot in your office not as a square of carpet or tile but a column of vertical space 12"x12" that you are leasing that runs from the carpet or tile to the ceiling and you can put in that column all that is possible. Several furniture tools are available to do that....one is systems furniture or modular furniture born in the 70's out of a need to put more people in a smaller space. This uses vertical panels and components that are attached to those panels and climb up the vertical column of space you are leasing....example, a binder bin is storage attached to a panel above the worksurface..carrying items that would normally be put in a file on the floor. 

Another effective way to use your 'vertical space' is through the use of lateral files. Lateral files are vertical files turned sideways  designed to go potentially as high in that vertical column as needed...we seem to be limited to local regulations relative to the sprinkler heads in the ceiling and the area around them to function.  So, employing an expert savvy in the use of 'vertical space' translates into $'s saved or maximized during the normal life cycle of a business.
