We moved from cube farms to hot desks with very low walls about a decade ago. Management was exstatic, saying how it would improve collaboration. Not so much. Not only did you get a wonderful level of noise increase as there was nothing to block the sound of the the sales dudes blathering and guffawing loudly on their calls, but you get the increased visual distraction as well. The low walls, barely over the top of your head while seated, meant that your eye was drawn every time someone walked down the row across from you. Headphones could partially compensate for the auditory distractions, but can't block the visual ones. It was very hard to do anything requiring concentration like programming or deep troubleshooting. The open office made it easy for the social butterflies to make the rounds and disruptively talk about trivial, non-business things to bigger groups of people since we weren't separated by physical partitions anymore. If you wanted to actually collaborate with a peer, you'd have to find a conference room because you damn sure couldn't do it in that noisy, chaotic environment.
Needless to say I and the majority of those who worked there opted for a full time telecommuting option. The office has been a ghost town for years other than the rare whole office meetings or the monthly cookout during warm weather. I've had to furnish my own home office, but it is peaceful and quiet.
