Actually, I have two garages. One is at my old house, 165 miles away. It has an 18' door. Lots of room inside. Just too far away and my nephew is renting the house. The one here is minimal, and my Kia Forte and an MGB fill it. It is difficult to maneuver around in what space is left, let alone fit through the 16' door. So... I want a nice bunch of space around the work areas, and with this plan I will have this central area that doubles, at least later, as a large, perhaps storage room. I will not put up this wall until after I finish work on the Europa. So my concerns are, as addressed, 120 or 240v, and for my neighborhood, how I will heat it. I really, I mean really, like my friend's garage. This is the guy who traveled with me to bring the Europa home from Moreno Valley. He used to live in Santee, and therefore had insight into what would be useful on a cold winter's night. His floor is heated by pipes that have a pump and circulate water heated by a standard heater. I would be very happy to flop myself down and crawl under the car on one of these floors. In the summer, the floor would provide coolness for free, too! A concern my friend has (he has 5 cars in a 4 car garage) concerns windows. I thought windows were a good thing, but he complains about the minimal (in my opinion) windows his garage has on two counts: a) they allow too much distracting light in, in that he needs to have brighter light inside to "compete" with the light the windows admit, and b) the windows preclude the wall shelf type storage opportunities. In my neighborhood, I have a 16' height restriction so the "rich guys on the ridge" can see over my house and view the Pacific. So... fitting a lift in the garage isn't precluded, but I won't be able to lift the 41" high Europa to service station heights. I do find, however, that working on the underside of the MGB with just jack stands, there are features I need to work on that are too close to my retired 57 year old eyes to focus on, so that lift could still be worth the bother and expense! So for now, my plan is to get the shell built, and insulate / sheetrock the one bay to store my, or a fellow club member's car, then deal with the Lotus project. I might just insulate the walls adjacent to the work area -- I might set up a spray booth -- who knows? After the Lotus is done, I can then sheetrock that side, and locate that wall to the center storage area. I get the impression that the wall location is arbitrary and that I can "adjust" its size after its mission changes...
