Some architectural doors I've built over the years. At left is a pair of Victorian outer doors for a client who wanted more light into the front hall than the original doors would allow. Below is an arts & crafts styled Dutch door.
Below left is a storm door with louvers so the clients could have privacy, but allow air movement. Screens behind the louvers can be replaced by glass inserts in winter.
At bottom is a federal doorway with half columns, transom window and coffered jambs.
