What are typical eave heights?
I'm in the design phase of a 1.5 story home with 10' room heights on the first floor, a long E-W axis, meaning a long wall facing due south which I would like to optimize for solar gain with intelligent window placement. This means that I'm prepared to haves eaves extending out about 4' or so from the exterior wall.
I'm not committed to a particular window height at this point.
Possibly conflicting with the above is the desire to maximize livable volume up on the second floor. By pushing eaves out further from the exterior wall and by raising the eave height higher, I increase the intersect line of the roof plane with the interior walls in the attic.
A lot of the above can be dealt with via online solar gain calculators and by playing around with planning software to optimize space on the 2nd, but I find that after playing around with this that I've lost sight of the aesthetic norm surrounding eave heights.As a placeholder in the design, I'm currently using 128 inches for the lowest point on the eaves. I'm feeling that this is a bit high, is it? I know that an eave that is too high is going to look odd, so my question is what are the eave heights that people in the trade see for homes with 10' ceilings on the first floor?
