New to the Forum, and hope I'm posting in correct area. I have an opportunity to buy a nice house on a great piece of property, but rooms are just too small. My question and hopeful plan is this. The house is currently 42 ft wide split entry that is 24 ft deep. I would like to increase foundation size to 30 ft deep by 50 ft long. I would like to know if it is possible to increase the house depth (the direction floor joists run) by 6 ft. This would allow me to move back wall of house out 6 ft. I believe adding 8 ft to the length of house is a fairly common addition. I have looked at using 30 ft attic trusses to gain storage space above first floor. Would these type of trusses require the use of load bearing walls below, or would it be possble to have some space run full 30 feet as one open room? Allthough I have done many remodeling projects in the past myself, this major one is all new to me. Would my first move be to contact a builder who specializes in additions, or to find a structural engineer to tell me if project is feasible. I guess I'm just not sure how to best get answers to whether or not my idea works. I greatly appreciate any insight tha can be provided.
