I plan on building a detached garage, Cape style 26x28 with a 2nd story 1/2 the square footage of the 1st story.

1st floor is to be insulated and sheet rocked. 10wx8h garage doors with openers. 2nd floor will have subfloor but walls will be unfinished and sheetrock will be delivered and left on second floor for the future. Electrical will be included with sub panel, but not sure of the amps. I received a quote for $52,000 originally , and it was lowered to $50,000 almost immediately after my reaction. After talking to contractor he said the foundation alone would cost him $11,000 and 15,000 for materials. I'm thinking the materials included the lumber and windows. He said he was going to work on the price and try to get the price down to 45,000. This price also included a a 26 foot driveway drain put in front of the doors. I live about 70 miles north of New York City. Any comments would appreciated.
