All replys have been excellent! I designed the structure to attempt to keep the wall height as low as possible. The issue is when you turn into our driveway, the bus entry door will be the first thing you see. Then, you will have to drive down the existing driveway, nest to the structure, thus I am trying to minimize the wall height. Don't want it to appear I am passing a warehouse on the way to my home.

Concerning the pit!. I do see it the way to go. Since I have not seen or worked with one, I am struggling with installing one. It is a possibility, but it is still simmering.

The center design will hamper placement of other equipment in the structure, but I think I can live with this inconvenience, to tone down the size of the building as I drive in.

The door is at 12 wide now. It seems to be the only way of fitting the 14 foot height door into structure's roof line. If I make the door any wider, the wall height will increase.

I do have a constraint with the size of the building. With a property building line, an existing building behind the proposed structure and the existing driveway on one side.

I have received advise from tdelorme concerning making the building 60 feet. It seems like the way to go.

I do intent to brick the structure to match my house.

Thanks for all the welcomed comments. They are all good
