hip roof framing
The carpenter who was suppose to start frame our porch tomorrow told us today that we can not do what we had planned (see scketch below) because the point where the hip rafter join the ridge cannot float in space and need to be supported.
Right now this point is 6 ft from the house wall. There is now an additional post between the house and the post on the drawing (so the span is not 15' anymore).
What are our option? put a beam across so we can support it , put one or several trusses between the wall and the point where it start to hip.
Any suggestions, we like to keep the space open to the framing (no ceiling)
