Over the years, opinions on the perfect office layout have changed. Once, offices were built out with rows of windowed and windowless private offices, usually assigned depending on rank, and limited numbers of cubicle spaces. Then, they became farms of cubicles with few, if any private offices. In an attempt to increase collaboration (and lower occupancy costs), some companies remove the dividers and create truly open layouts. All three styles of layout have their pros and cons. The right layout for your company is the one whose benefits match your needs and whose detriments are not concerns.
