Hip to hip roof

[akist]

Hello,

I have a question regarding a hip to hip roof design.

I have designed the structure of the roof with the intention to build rooms in the loft, and so I made the top ridge quite wide, which resulted in the hips being at 60 degrees instead of 45. This resulted in the pitch of the front and the side being different, with the front and back pitch being shallower than at the two sides.

This difference in pitch between sides and front/back has resulted in the hip tiles being a bit lob sided and the roof tiles at the sides reach the gutters at a sharper pitch than at the front and back.

The solution proposed is to place the hips at 45 degree angles, thus making the top ridge shorter.

I was thinking however is it acceptable/done for the hips NOT to be at 45 degrees and have a wider top ridge and some sort of way to deal with the different pitches?

What about building the side up a bit? Think they call it a Dutch End like this:

That way you can keep the longer ridge and maintain the 45deg angle.

No, you have not designed. You've cobbled.
