I am surprised you are getting so many positive comments. I see lots of wasted space. The borrom RH corner with nothing makes no sense at all. That should be a stall back into the corner with the door moved. The aisle ways are huge and the corner by the lounge is really awkward and I do not like all the hard corners in weird spots, the quarantine area is gianormous and it gets the paddock while the small stalls get nothing. 14x14 wash are would be ok but not with the indentaion.
As far as your concerns go:
1. The little area in the bottom right-hand corner next to the LG stall does not truly have a purpose, however I didn't like the idea of making it part of a stall simply because of the size difference. It would mean that I would have one large stall of 16 ft in length with another next to it that would be at least 18 or so in feet. (I don't have precise scales so I could not say for certain the exact size.) While this size difference isn't that much of an issue for the horses in them, I can see it being a problem with the owners.
"Why is so-and-so's stall bigger than mine? I want the bigger stall for my horse cause he's likes bigger spaces!"
I wanted to include one stall of a larger size so that I could have the option for boarding at least one draft type horse if I so chose. However, I don't particularly want too many---as I am not accustom to their handling differences or needs.
If that stall was not needed for a larger horse, I could simply put my own in it and if asked about the size difference I could easily say "My horse, My barn, I use the biggest stall." Without making other people feel like I have favorites or something.
Also, I left the area open to make it a bit safer for the horse in the right bottom stall. When that stall door is open I wanted there to be a wide area to bring the horse out into--- with little chance for a horse or human to be trapped in an unsafe area. Besides, it gives me a nifty little place to store a wheelbarrow or cart.
2. The aisles are quite large, I did this on purpose. At the facility I currently work at the aisles are one of my major issues/concerns. They are approximately 12-14ft wide...In my opinion this is not enough room. When horses are tied to their stalls for daily cleaning (which happens all at the same time where I am) there is barely room to pass by the horses' hindquarters. When walking by you are in a 2ft space between horses on either side of the aisle. In a configuration that looks like this -- But with 10-15 horses in a row on either side.
If any of these horses were to spook or fight with one another while someone was trying to walk through the aisle it would be a disaster. A person would be trapped between the horses with no way of escape.
To avoid situations like this, I placed the mini-stalls directly across from the larger horses stalls to make the aisle 16ft in the smallest width. Larger in some other areas.
The corner in the right wing-- just below the "q-area" is left open for future development. It could be used for a variety of things,-- I did not want to overcrowd the barn with things I am unsure about. I imagine that It would be used as a small storage area for larger objects such as:: Dividers, wheelbarrows, shaving bags, extra hay during winter etc.
3. The Quarantine area was made so large to allow for movement while still restricting it somewhat. The reason it also gets the paddock is because of the actual Quarantine usage. The other stalled horses would most likely get daily turnout in established pastures for grazing. This would not be possible for a quarantined horse due to the impossibility of providing a sterile area outdoors in a pasture. The quarantine paddock would be nothing more than a drylot with some access to fresh air, while it would also be impossible to completely sterilize. It would be much easier to keep clean than a pasture. It would also keep other horses away from the quarantined animal due to the fact that the pastures would not be directly next to the barn.
I hope that cleared up any problems
