Well I've managed to clean out the Terrain Workshop. Sadly, the bulk of the "debris" consisted of various shipping boxes that were retained for storage or to use in building terrain. Of course neither of those objectives were fulfilled.
This space measure 8x8 and serves as both a terrain workbench and storage. The big plus of this apce is it has a pair of doors which can be closed and hide the mess from the wife. She has learned long ago that these doors are best left closed.
I've got the bulk and most commonly used scenery materials in a shelf unit right next to the work bench.
If we pan in a clockwise direction one can see 1 of 2 small parts bins - this one has small terrain items like various grass tufts, different grades of sand and special small detail parts.
In this corner, I store my unfinished hex terrain (just cut hexes in the boxes and my collection of 2x2 terrain panels.
