The entire summer of 2005 was spent working on adding the details to the garage. The cold weather was coming back quickly and the last remaining item was insulation. The walls of the garage were built using 2x6s instead of typical 2x4s. This was to support a potential second floor and to provide deeper walls that could accept 50% more insulation. A 100,000 BTU heater would make for high heating bills if the building was not insulated properly. Remember that the garage has heat, air conditioning, cable TV, phone, and even wireless internet at this point. Shelving helped keep junk off the floor.
