I'm designing a house and want to have 4' gable overhangs on the back of the house. Any recommendations for how to frame this would be helpful. I would imagine 2x4 lookouts would not be enough, so my initial thought was to build a 2x8 ladder that would span 4' out and 4' inside the gable wall. Anyway, I was struggling with this one so I thought I'd post... Obviously I haven't finished certain details (like the gable wall), but you get the picture. Thanks!

This generally requires an engineer but there are essentially two ways: ladder as you specify. I did one and there was significant use of Simpson L connectors and hurricane ties.

The other way is a structural ridge and structural continuation of the top plate as a besm that can handle the 4' cantilever. In some case the eves fascia can support the bottom.

There can be considerable uplift loads on these overhangs, hence the requirement for an engineer.
