I tried to get this as accurate as possible to the office shown in the show. I'd have loved to have made a trap door but even with the heightened base it wouldn't drop a Minifigure clear. But I put the button on the desk next to the chair to be accurate anyhow.
I designed the chair and phone and clock and desk but I think I got the design of the lamp from Lego and tweaked it a bit
i didn't intend the power plant style base but the idea hit me when I got the batman movie sets and the curved red pipe piece plus it was a good way to incorporate Blinky the fish which I wanted to do.
I think on future I'll add the curtains and some walls to one or both sides.
