I have set up two so far. In the blog section I elaborated on how I got a Ritter box table out of the old house and into an open trailer in the middle of the day by myself and without raising any eyebrows. The trick is to take it apart so it looks like a desk. I also elaborated on a device I made that makes it much easier to get heavy things up and down a staircase.
Someplace else I elaborated on how I concealed the rooms. The old one was an offshoot of my office. I could have thrown a sheetrock wall up to hide the last 10' or so of the depth of the room, but I opted for one of those floor to ceiling curtains made out of slats that rotate. Shut them all the way, hang a few posters up on them and people never gave it a second look. My desk was more on the entry door to the room side so people never really got to the far end of the fake wall where I would pull it back to gain access. If you live in an apartment and don't want to do any "building" those slat things work real well. If you hang some posters and stuff up on them they look solid to the unsuspecting eye. If you own your own house you can make a wall out of 2x4's toenailed in and covered with sheetrock. One other thing I did for one of my actual offices that was in a bedroom when I lived in an apartment was I took a few of those $30 particle board bookcases and screwed them together lengthwise so they made a wall that was near floor to ceiling. I screwed one of them into an actual wall so they would not tip over. That is just like 3 holes so if you are a renter, it is easy to fix when you leave. Than on the backs, I put up sheetrock, floor to ceiling, but it was only attached to the bookcases. Nail on a strip of molding to the bottom of the book case (not the floor, but the book case) and another up at the top, and again the top of the book case and not the ceiling, and you have a very solid looking wall that is only attached to your book cases. Plus id you are an apartment dweller, all you need to build this is a screw gun or a strong hand with a screw driver and a sharp pallet knife to trim the sheetrock. If you paint it and are sly, you can get away without any mudding or taping by carefully arranging things on the wall. I had a big whiteboad hung up that covered most of the joint between the two sheets going lengthwise for example.
The new room is in it's own space and well hidden. I was going to only have my box table in there but I got the deal of a lifetime on a female procedure chair that was broken and took a little bit of fixing. So now I have the box table and the procedure chair side by side out there. I don't have much in the way of cabinets but the box table has drawers in it. I have two fiber optic exam lights and my autoclave out there, as well as an exam room scale and a few other knick knacks. Mashie pointed out the base to my antique bird cage that makes a really ideal "wallmart" enema bag holder.
I am always on the prowl for new goodies for out there. I kind of have a bug of my ass for an old patient monitor but I want one with the attachments and have yet to find one at a price I can afford.
Anyway, it is not real hard to snip part of a room off and you will be surprised that no one ever notices it. I was amazed with the slat wall.
