How Many Doors Does The Average House Have?

So I have my floor plan, and the basic walls up for both levels, it's time to nail down some details. The main issue I'm having, since I'm not an actual architect, or contractor, is that I know nothing about these details. So, with tape measure in hand, I start measuring.

I start off by modeling all of the doors need for my building.

Before I can start, I have to answer a few questions.

•How wide is a door supposed to be?
•How tall is a door supposed to be?
•How thick is a door supposed to be?
•What is the radius if a door knob?
•How high should the door knob be off the ground?
•How wide and thick should the trim be?

This is the basic door that will be used for all interior doors. I also modeled the door jam as part of the door.

This is the model used for both exterior balcony doors on the second level. One will provide access to the balcony from the master bedroom, and a second one for the Home Theater/Media room.

Here is the initial model of the front entrance doors. I still have to model the door handles.

This is a bizarre image of all of the doors in their proper place with the walls removed.

I have no answer for the initial question of how many doors the average house has, but this building has 20 doors total. That's a lot of Keys!
