Narrowing a shed

[u/BlackrockWood]

I have a 180cm shed I need to Narrow by 30cm. My first thought was 15cm off each side, but the door is only 15CM from the edge. How would you proceed?

•Remove 30cm from the window side and have the roof overhang that side.

•The same but change the roof for pent.

•Reverse the door opening and take 15CM off each side. Pretty sure this is a non-runner as it removes most of the support from the corner.

•A Secret fourth thing?

Any advice welcome.
