Of course. But a private, home barn is likely to be utilized by the farm owner. I’m simply saying that it may be an unnecessary expense. That’s why I asked the OP why she wanted feed doors in the stall.
I much prefer stepping into the stall and placing hay/feed where I want it - not, for example, on a pile of manure, if there was one just below the feeding door. Or, I can slide the stall door open 8" and put 2 flakes of hay on the floor.
There are a lot of cool features that anyone could buy, but maybe not really all that awesome in practice. I had wall mounted feed troughs for about 3 days before I had them taken out. Somehow they managed to get pooped in and were a huge PITA to clean in comparison to feed pans. It seemed like a good idea at first. Maybe they were mounted too low, but in the end feed pans were much easier.
