This was a bare room...not even flooring. I took all kinds of measurements (3 walls), and fabricated the whole room in the shop to the point of having it all assembled, and then taking it apart, delivering it, and installing.
The apartment was on the 8th floor, and all the tools and parts had to be carried, rolled on dollies, and in and out the elevators. Tools had to be removed at the end of each day. What a PITA. But, the client loved it.
