We are building a veranda across the back of the new extension, and a
car port up the side of the house to link with the veranda and provide a

The main veranda and car port are pretty straightforward but the corner
where the two meet requires a bit more thought.

The solution appears to be a hip, joining the two roofs sloping in
different directions.

The triangle calculator suggests the hip will be 5.3m long.

seems to suggest that 72*220 (3*9) C16 might do the job.
However this is for floor joist sizes on a ground floor.

You have missed the one bit of information that would be needed to make
sense of this - the type of roof you are expecting them to carry...


Ooops - 10mm polycarbonate using glazing bars supported by wood.
