Good design and architecture is about much more than color and style, but how many of those other elements are most people aware? A good designer understands purpose/function, materials and systems, users and use, building process, hard and soft costs, life-cycle costs, and a host of other factors that shape the final building. Planning and design impact how appealing and accessible your business is for walk-in traffic; employee productivity, the flexibility of use, room for growth, operations and maintenance costs and a variety of elements with intrinsic value.
You may be able to improve your bottom line simply through better design. Good architecture is invisible, but its value is obvious.
