The wall panels are part of the Gridwall system. It is used a lot in retail store displays. The panels are heavy gauge steel and can support way more weight than you would think. They panels and hangers can be purchased online from Amazon and many other sources. I ordered some of mine from ULINE.com. Most of the hangers are generic gridwall system parts. For specialty things like the bridle hangers I used:

They also sell the grids as well. There are also picture hangers for the system, and shelves too. I started with the wall grids, and added hanging hardware as I decided where things went the best. I like the grids because they don’t hide the wood wall behind them and make things feel more open. Plus, re-orgainzation is simple; just move the hangers.
The storage cabinets are from:

They are shipped assembled and with all the hardware installed. They come unfinished, so I sanded them and applied the same oil-based polyurethane as the barn builder used on the walls. They also make feed bins and feed room storage cabinets. The desk, stand for the mini-fridge, the feed prep table, the saddle cleaning stand, and the saddle pad rack I built myself.
Saddles are stored of wall-mounted single tube racks that I believe I ordered from Schneiders. I have never sold a saddle, to me they are like old friends. Although I did give a dressage saddle and cross-country saddle to my niece when she started eventing last year.
Thanks for the compliment.
