Throughout the years working in the design industry I have really taken a liking to the aspect of space planning. Creating an efficient layout and flow to a space ideal for communication, entertaining, or supervision if its an office space.
With the homes I work on and tweak the floorplans to get the ideal space and flow making it manageable. Rather than creating something for the sake of creating something it is far more important to get into the mind of the clients. Create a space that fits their needs from residential to commercial.
Although at times space planning can feel tedious, the end result shows the thought put into it. Always smart to have someone who is space planning savvy.
Also there are many iPad and tablet apps now to help you with space planning if doing it on a budget.
