It is 3160 sq ft. Twice what I have at my home shop. plus I have alot of room above my office for storage. I have a little gas powered tow motor that reaches 9 ft 2 inch, my office roof is 9 ft. Just makes it! awsome for unloading and storage. I thought the power converter would be really loud but it is so quiet it's crazy! I think my dishwasher is louder than it is. The booth is loud tho. here is some pics of my office. I will have paint samples and chrome lettering of my business name Zinger Customs on the wall with the racing stripe. The ceiling and walls are dry walled and textured with a knock down and semi gloss paint. I spent several days on scaffolding spraying that ceiling! My back was shot as was my neck. heres more pics.
