A few,haha.
Built dbl doors for our 1810 Federal period house that are going to give somebody a big suprise down the rd when I'm looong gone.
My mom was a "shapely" woman....you know the type,maybe 75 lbs over weight.When designing the fr doors,had to see how small an opening she could easily fit through.Already having a pretty good idea....just wanted to make sure,haha.
So,I intentionally made the doors a non std 44" total opening.Each door is 22...duh.And they've been in use now almost 30 years.The point was.....when I'm gone,and basically as looong as this house is standing,no-one is going to hang some cheapo,home store doors on this lovely house.And we're talkin full-on door surround with ALL the bells N whistles.....so it'll take an act of congress to change the opening.Haha.
Generally,your biggest concern is wood species....and it's relationship with how the area interfaces with weather.You can not beat mother nature.
