A business needs its own office premises for a wide variety of good practical reasons. The type and size of office and its geographic location are likely to depend on a number of reasons including costs, proximity to markets and skills, and availability of premises.
The internal layout of offices is likely to be wide and varied, and very much related to original layout of the building itself. Asking why a business needs office partitions raises more questions and important points which tend to indicate that there is indeed a great and increasing need for them in the business world.

You can look for office fit out firms which can not only design office layouts, they can also provide custom made workstations and office furniture, wall partitions, complete modern color schemes, carpentry, cabling, plastering and painting.
Is there a need for individual offices or dividing the office space?
In most businesses, just as there is in the home, there are many good reasons why certain functions or events benefit from and are facilitated by some form of physical barrier or separation, or privacy and insulation.
Businesses are highly likely to have hierarchies of authority, and specific functions being performed by staff that are dedicated to, and are specialists in that one specific function or job itself.
Often the management function itself is divided among certain key personnel, and these personnel will require their own area / room / office too.
