I thought to take an opportunity of a mild (~10C) and dry weather this afternoon, so after a visit to a local home despot for wood and drywall, I went ahead to frame the diagonal wall on the left side of the layout room. This was an almost 7 ft. opening that had to be closed first if I was to begin (finish?) any benchwork construction in that area.
Past several weeks have been spent building the closet area that my spouse had been waiting for (what seems an eternity). It was a slow process as I only had couple of hours after work, and then couple of weekends, of free time. At the end, it turned out nice and my SO is happy with the looks. Still need to put some shelving inside, although I do not foresee any issues with that (might re-use the sub-roadbed that was in this area originally).
