I am planning to build a vacation home with 1.5 floors and would like to have an airy living room on one short side of the house with large windows facing the water. The living room will be open to the ceiling, but there will be a furnished upper floor in the rear part of the house. The size of the house can be 7.2x10.8m or slightly larger.
Is it common in this case to use a glulam beam from one gable to the other in combination with truss rafters? Would it be smarter/cheaper to use a glulam beam only in the living room attached to a (reinforced) truss rafter? What is recommended and not?
