I am tearing down a two-car garage and building a three car garage. Because of permits and what not, the size is going to be 21 ft by 28 ft. I know that I will have a single garage door, 8 ft by 8 ft, and a double garage door 8ft by 16ft. We have having it built, but I will be doing the insulation, drywall, trim and paint with a buddy. Couple of questions I have: Lighting: Are cans ok or do I need more than only cans? Light is a big deal for me. I see a lot of garages that have lighting over the CAR, and not over the space BETWEEN the cars. It seems like you would want to put the light over the gaps in the parking spots. Any thoughts? I was thinking about having four can lights on each side of the cars (four rows total). I might add secondary long bulb/work lights above each car just in case I need extra light - but I am not sure about this. The only reason I am thinking about this is because cans are always facing down and don't cast light all around. Heating: Is there a specific temperature that it is good to keep a garage to? Above 40/45/50/55 to protect leather/rubber? This is a detached garage in Chicago. I am not trying to keep it 72 degrees all year long, but I am trying to keep it from getting below freezing. I was going to get a 220v heater and keep the garage around 45 degrees or so. I thought about running gas but that would not be easy in my case. Flooring: Any word to the wise for putting down the epoxy floor other than reading the instructions and YouTube? Electrical: The heater will need 220v and I am considering pre-wiring for an electric car - but I will need to talk to the electrician to see if there is a problem with having both. Anything else that you really enjoy about your garage that I might should consider? .
