I love jam spaces. Classic "Third Place" that can feel more like home than home. I like looking at other's not only for the gear porn but also for good ideas as regards organisation,/layout and general mess management - most of us are making due with not quite enough space; spare bedrooms, attics/basements etc. Post pics of your music cave here, and I guess we can talk about related issues too.
This was the studio/venue I was running for a while (Polyhaus). Closed down for a number of reasons, but mainly that the lease was up a couple months before my daughter was due to be born and I would not have the time to run shows (required to pay the rent on this place) with the new kid so I just let it go:

The wood balcony thing is the AV loft (front of house + projector control). My studio was the room to the left of the stage. Inside there (old pic, forgot to take another one after I finished wiring up the patchbays and hung up the cloud):
The fisheye lens really distorts. The room was designed by me to be a symmetrical (on the axis that bisects the mixing position and the drum throne) septagon (the wall behind the drums is actually 2 walls joining at a rather obtuse angle - something like 120-140 deg - behind the throne, and the wall in front of the mixer is actually 3 walls, the side 2 joining the middle one at 60 degree angles - which was a perfect toe-in for my soffit-mounted monitors) with no parallel surfaces (aside from floor and ceiling - was gonna slant the ceiling but the shape was already weird/hard enough to build). Sounded awesome in there. RIP.
Anyway, after stabilising my life again (with regards to the children and their routines), I have a new spot. No shows (still no time for that) just studio. Currently setting that up. Pics soon - I got just enough stuff moved in to jam, but my bass traps are all stacked in what will soon be the mixing nook, and one whole wall is a mess of tools and random supplies.
