This is what my workshop looks like today, much condensed. On the left is my valve stock and cabinets on the wall for other items.

I started off working on a bench at the back of the garage. But conditions were rarely in the "Goldilocks" zone.. it was usually too hot or too cold for comfortable working.
So I made up a large wooden "tray" with shelf above for test equipment, light and power board to the rear. This just sits on the desk in the study providing me with a year round work space without damaging the office furniture.

My only suggestion for these workshops is the addition of a screen in front of the desk lights to stop the globes shining in your eyes.

Seeing that mine is basically a fully insulated separate (Steel frame) shed (14' by 30'); More liberties. The shelf over the bench is over 2m long & 500mm wide. It has LED strip light under it. This is a clip in racking type shelf that is easily altered and there are two more narrower shelve above this one.

There are two moveable 2x 80W fluorescent lights mounted in the recycled cover of a defunct 8 foot unit over the radio bench. These van be switched off when you don't want to drown out the oscilloscopes and a separate moveable "troughy" in the back ground on another rail for back light so that you can still see what you are doing on the bench (normally during calibrating)

Computers /printer/scanners, have their own bench also with the same sort of shelving behind them.

This was originally an Art Studio & that is why the lights are not fixed & set up to slide along the purlins & be chopped & changed around at a whim: Plug in.
