Great topic!
My ideal office would have a built-in bookshelf on one wall that also holds a 27" tv. A large oak desk, solid with deep drawers with a nice globe and then several large wall maps. I would want a large deep burgundy office chair and a few more chairs - perhaps two and then a loveseat and coffee table. A couple of large windows with a great view too, of course!
That's been my 'dream office' for awhile now, though I have to say that I really love the set up I have here at the new place. Before the move I had my office in a separate room, but it was in the center of the house and a high traffic area. Perfect for managing the home with 2 children and Grandmother while working... but *very* distracting lol.
I moved into a conservative 3 bedroom brick home in a quiet neighborhood... and I thought very hard about where I wanted to set up my office here. I finally settled on the master bedroom - for complete peace and privacy - and so far I am loving it! I have my antique bedroom suit in here as well as my L-shaped wood desk and still have plenty of room. There are also two large closets in this room so I am using one of them for my filing cabinet and general office storage, which I think will keep things much neater.
My second favorite place to be is in the recliner with the laptop, which is nice after the kids go to bed and I feel like sitting up and watching movies while reading or researching during commercial breaks
