The thread reminds me of two places in particular.
One was an Arabian halter horse show/sales barn. This was back in the days of these horses being seen as “collectables” and status symbols. (Before tax rules changed) The stalls were not absurdly over the top, that was reserved for the places the clients or buyers would see. Those people would be ushered into the lobby complete with chandelier and up the staircase to the lounge with leather chairs, a bar and fancy sound system. Then they turned on the special effects lights and the smoke machine in the arena while the horse was prepped out of sight. The first the buyer saw it was when it charged into arena, snorting and flagging its tail while inspiring music played!
The other place I went to audit a clinic. T shaped barn with numerous grooming and washing stalls. Dark wood and brass stalls, but more impresssive to me, all the stalls had outside windows the horses could stick their heads out of and pleny of grassy paddocks that were actually used. Beuatiful outdoor arenas and hacking paths. Lovely indoor with windows that could be rolled up like garage doors all along the long side. I was impressed at the though about use and horse comfort. But then… for some strange reason there were life size statues of large zoo animals sprinkled around the grounds.
