Here's a poor man's floor plan made in 5 min. Used Grizzlys free software and couldn't find everything. Quick tour:
Left wall is the breaker box, miter saw station, two windows, and dust collector.
Center is tablesaw, outfeed table/router table, jointer, and planer.
Right wall is fridge, counters/cabinets, and lumber storage.
Back wall: sink, band saw, drill press, central vacuum system (for the house only), and a water heater under the stairs. Front Wall: garage door (obviously). I could put stuff in front of this I guess
I'm certainly open to other arrangements!
