Hi Stew,
Great to hear you’re about to get a shop. I’m on my fifth or sixth shop, now in a double car garage. A couple thoughts:
-for the last two, I designed them with sketch up. In the last shop, I printed out a version on paper and that was easier in the end. In both cases, the exercise was merely a starting point for knowing that all the machines could fit with reasonable clearances around them. But it took literally years of fiddling to get to the current configuration and I’m probably not done!
-the most important thing I’ve done to improve the shop has been to build a separate shed for the majority of my wood storage AND a bunch of the “stuff” that one finds in a garage.
-the biggest improvement I could make would be to separate the shop from a garage because it remains a constant challenge to keep “stuff” from accumulating in the open spaces and flat surfaces as we go through daily life. Separating storage/garage space from WW space might be more important than the absolute amount of space once over 300-400 sq ft. And becomes even more important in shops smaller than 300 sf.
-go read through Derek’s website on his shop layout if you haven’t. I have a slightly different layout but followed many of the same principles.
Will enjoy watching your progress!
best,
Chris
