Hey, we are building a garage as an addition to our house. It is 32' by 32' and we are wanting to have a room above the garage. My question is, when leaving our openings for the garage doors, what type of lintel would you recommend using that would support an upstairs? The doors are 10' wide. Thanks for any advice.
the header should be sized based upon the loads it must support. this includes live, dead, snow, and wind loads and any seismic loads.
if you are putting living space over the garage will your joists and rafters need to be supported by the headers? hard for us to know what you are planning on since we don't have any drawings to go by.
check with you local building department to determine your building code and it's requiremens.
