And here, finally, is substantial completion of the gym area!
The floor looks great, combined with the rubber mats it really absorbs impact. And the room is holding a steady 62 degrees, which is about a 15-20 degree improvement this time of year.
All in all, I'm pleased with how it's turned out. Still have a few things left on this section, but they're minor. The room is functional now.
Once it warms up in a few weeks, I'll tackle the brewhouse/workshop section. Hopefully that won't take quite as long!
