That's the direction my wood shop was going before a bike shop exploded into the space. The "annex" is for the dirty work and unconditioned bike and junk storage. The clean bike work I hope will coexist well enough with the wood shop. I'm pretty heavily invested in dust collection, and realy don't want to build to many more kitchens/ plywood boxes in this life time.
I could still get talked into solid wood stuff...
