Alright I am in the prelimanary stages of building a 3 car garage. It will be attached by a breezeway to our home. So far I am looking at a 42X32 3 car garage with trusses so we will have storage space above. I will be using it to store by boat and my wife a daughter a parking space. I plan to put a trough drain in the rear as well as add windows to 2 sides of it. Help me out guys on what I am missing. My home is a farmhouse style home and we will be adding a dormer above each garage door to match the house. Thanks for any helpful tips you guys might can throw my way.
