Form and function are the two primary factors in any design scheme. Whether you're designing an aircraft carrier or a sock, the principles must work together to ensure that the outcome is not only attractive, but serves its intended purpose. With this said, it becomes quite easy to discern how business interior design differs from home interior design. The form (the look) of the plan must follow the function (the needs) of the location.
In a home setting, you have a set of needs to meet. They are very different from those of the staff occupying office space. Still, they do have some overlap. For instance, while the sort of chairs used in a living room might differ slightly from those in a waiting room, you'd still want them to be comfortable and inviting. In the same vein, a table meant to seat a family for dinner and a conference table seating sales executives would have many similarities. Still, there are more than enough differences between the schemes to ensure that a separate approach is used to planning the final look for either.
In the office, the functionality of each piece and their seamless integration into the mechanism of the working environment is essential. Interpersonal or interdepartmental, there is a need for the work place to invite shared information and yet, also some implicit boundaries are needed, too. The complex issues involving laying out an office interior are so involved that many designers specialize in just this sort of work when studying for their degree.
In the home, on the flipside, many rooms are separate. Bobby and Amanda's bedrooms don't need to communicate. Plus, home furnishings tend to be softer, comfier and a lot less formal than office pieces. So, you see. Once you understand the differing dynamics of their individual needs, it becomes quite simple to perceive how business interior design differs from home interior design.
