I live outside of Boston, MA, grew up on Long Island, NY. I currently have a regular 2 car garage, I did Epoxy the floors and they have held up fantastic the past 3 years. I may be moving in the near future so plans to build an additional Garage at this point, but will certainly be looking to at my next house. I will never get a regular 21X21 garage again, unless you plan to use it for just 2 cars it is really a 1 car garage with room for other stuff. My last house had a 25X25, it is amazing how much more it could hold. I fixed that one up pretty good with painted OSB on the bottom and white peg-board along the top, came out great and held all of my stuff.
Looking at the site would have gave me a lot more ideas, looking forward to building a garage after seeing some of these.
