it's 12 feet Bjorn. Great minds draw alike

Brian the front overhang is about 5 feet (notice the slope drops lower).

The dormers house a loft area with shower, more lounge space and access to storage above the lower rafters, if I just put in skylights I would be self inflicting a lot of head injuries.

I will be hand sketching the floor plans, sections and elevations now, unless I can find my autocad LT discs as they are not on my newer puter.

I always liked the look of a good hand drafted set of plans anyhow.
