how much space should you allow for each pin width ways. Back box is about 74cm ish. (is a backbox on a widebody game any bigger? ) you need to leave a bit of room to nudge though without them hitting each other. so for 4 pins, is 3m 20cm enough space, or would you allow more?
Im planning something like this, so I want to work out how long the wall with 4 pins will be so I can work out the length of the longer wall to keep under 15m2.
Also, the roof will over hang to create a porch area, does anyone know if that will count as part of the 15m or is it only footprint of the building on the floor that counts?
