My wife and I just moved into a new house. The basement is where my new brewery is set up. I run two 7.5gal Blichmann G2 Boilermakers with natural gas on two Blichmann burners. I have a Blichmann Tower of Power & RipTide pump that I use for temperature control and recirculation. I do 2.5gal BIAB batches with a stainless mesh basket from ArborFab. With the two pots & two burners, I double batch every brew day. I off-set the batches by about an hour. This means that while mashing batch 1, I'm heating mash water for batch 2. While boiling batch 1, I'm mashing batch 2. It has worked out well.
This is my first "leave in place" brewery. My last house was a pretty good setup in the garage off the basement. The basement was such that you didn't mind when you spilled a litte (or a lot). Garage brewing was fine. Did it for 8 years, but I had to bring everything out and put it all away for each brew day. Not awful, but it'll be nice to have it all set up.
As you can hopefully see in the pictures I have plumbing (copper pipe), drainage for the chiller (PVC pipe), electric, and ventilation for gas & steam. The idea for vent hood came from HBT users & the idea for mounting the hood on a TV arm did too. The shelving & work area are more than adequate for all the items I use. And the fermentation fridge and keezer are off on the side too. And if you look close you'll see I've got my speakers set up too so I can have my tunes playing. Currently, I'm listening to a lot of Ghost.
I put the finishing touches on it on Monday by putting up my brewery banner and putting my RO system on a cart to make it mobile. It's ready for brewing on 10/15 when I'll brewing a BIPA/CDA and an Amber Ale.

Looking forward to the inaugural brew day!
