Here's another case of hide the house to make the track look more complete. This time its the rear marshall access door. I started with a shelf anchored directly to the door and then added some 2 inch foam rock base. I made three buildings of decending sizes and oriented them along the door face. The left side of the left most building actually stays with the wall and door frame stationary while the remaining right half and other two buildings swing away with the door. This way for big race nights you can open the door for a marshall, otherwise its closed for a more complete scenic look. These buildings are all gatorboard with flat wood stock trim pieces. I did a few antennae platforms too to cover up some more of the door moulding. The buildings are elevated to accomodate a small lot to park a few cars on.
