It depends where you live and the local building codes. Do you need to
take snow loads into consideration? A pole barn is just some poles
buried in the ground with a wood beam around the top to support the
roof trusses. nail 2x4s horizontaly between the poles to give support
for the steel siding. It doesn't cost much more to build a full hangar
instesd of a T and you will always be able to find stuff to fill the
corners.


Yes snow load is a concern... I live in Manitoba Canada..
