When we chose our floor plan, I knew that I was going to want built-in cabinetry and a floating desk, so we pushed out the wall by a foot. Which was a plus all-around since it enlarged our master bedroom, bathroom, shower room and closet! :) Umm, yes please!
I still am slowly adding knick-knacks to my bookshelves and desk space, and I definitely want to add a linen upholstered desk chair. But other than that, I've pretty much completed the decorating in the office.
Since there is not a room above my office, we decided to give the office a bigger feeling by removing the ten-foot ceiling and making it a cathedral ceiling with a cedar beam.
And one huge plus of having the custom built-in cabinets was being able to be very picky on the desk set up. I hate having ugly, necessary things in view. So, I requested rollout shelves that fit my laptop and dock and the printer. We made sure to have outlets built inside the cabinets and a large drawer that could accommodate hanging file folders, should I ever need them. Then, I had them make the cutout for cords go straight into the cabinet so that they're as invisible as possible!
