For high ceilings talk to your builder about whether 10 or 12 foot dimensions are best.
Door height for 10 foot ceiling.
Hope nothing major is facing west.
Here is an example first truss bearing columns at 12 feet from endwall 10 foot eave height nine foot tall overhead door top of opening should be 9 2 1 2 above grade with a residential overhead door.
Then tour homes similar to yours with a range of ceiling heights to assist in making your decision.
Matching the window and door height to the space.
Good luck on your project.
My rule of thumb is to use the 8 0 doors when you have tall ceilings or to use transoms with 6 8 doors.
With placement of the overhead door at the center of the endwall here is my answer to.
Window replacement is typically determined when designing the exterior of a house with the height set to the standard door height of 6 feet and 8 inches.
With a standard 8 foot wall height this placement leaves a margin of 16 inches between the top of the window and the ceiling.
Furthermore a change in ceiling height from room to room really added a nice juxtaposition between each room even though some of the rooms were only separated by archways.
This leaves all of 9 1 2 between top of door opening and eave height however you also gain height due to the slope of the roof.
Also consider the width.
I try to use 3 0 wide door where possible.
Standard residential door heights are 6 8 and 8 0.
If you use 8 foot doors and crown molding you will still get that grand feeling with 9 foot ceilings.
That is contrasting ceiling height turned out to be a nice feature.
The rise or height of a step is measured from the top of one tread to the top of the next tread.
My instinct and experience says we need minimum 2 especially with a 14 high door but it never hurts to ask this would be needing two feet of eave height greater than the overhead door height the building in question has a 40 foot wide endwall.
It is not the physical height of the riser because this excludes the thickness of the tread.
Building codes generally suggest that the minimum length of a tread be 10 inches 25 4 cm.
Fwiw the higher the window head the more natural light will penetrate the interiors.
With a 10 foot high ceiling i d use 8 foot high doors and set the window heads at the same 8 foot height.
