I had nearly identical plans in mind! Right down to the laminated counter top.
My only hesitation is that this will be dedicated hobby space and won't need to carry a lot of weight. So, I'm wondering if a constructed workbench will be overkill.
I'm debating if I should just mount some laminated counter top in bar-fashion in an 'L' shape along the two adjoining walls (mount directly to the wall with counter support brackets). This would allow me to work anywhere in the 'L' without banging my knees on the legs of a workbench. If additional support was needed, I could install cabinets under each end of the 'L'. *shrug*
I'm scouring the inter webs for inspiration and ideas!
