Interior architects construct building designs by combining interior design and architecture. Their objective is to use factors such as light and color to create efficient, elegant rooms that fulfill their clients' aesthetic and operational demands. Interior architects work for architectural firms or corporations, but some also work independently. They start with a meeting room assessment chart to determine what kind of space will best meet the needs of the company. From there, they develop a plan to incorporate any custom features desired by the client. Finally, they translate the plan into drawings which are then sent off to be built by carpenters and other construction workers. Architects usually provide guidance to their clients on the most effective way to utilize space and improve overall building aesthetics. They might help select material styles and colors for walls and floors, for example. Occasionally, they are even asked to design entire buildings from scratch. Most often, however, they work within the framework of existing structures, using their knowledge of interior design and architecture to make improvements that were not thought of originally. For example, an architect might have been involved in the planning of one floor of a building and then be asked to come up with a new plan for another floor after seeing how that first effort had been used or abused. In this case, the second plan would probably include some elements from the first plan so as not to reinvent the wheel.
