I have two home offices. One for professional work, that is, stuff related to being the CTO of BrainSell Technologies. The other office has an 8-foot long desk with a microscope, a shortwave set and a linux computer on it.
Opposite the Desk is a workbench with a radial arm saw, a delta uni-saw, a drill press and a band saw.
At the other end of this office is a tool crib.
I keep the place warm in the winter with a 30,000 btu vent-less propane heater.
