I am "lucky" that I got a large computer desk from Ikea many years ago. It holds 2*pc's, 2*monitors, keyboard drawer, b&w laser on top of a paper "filing" cabinet, and a tun of junk that I am "working on".
Not got a garage, if I had then it would be fitted with power and water so I could brew there! Got a shed with my Triumph Sprint in it, along with a bath I will get around to fitting one of these years, and assorted other junk.
