The building has an approx. 9' side bay, then a 10' door, then on the opposite side of the door it's approx 16' wide.
The 9' side bay is approx 8' tall. The peek of the roof with the opening is approx 22'.
30'w x 85'L overall. They may very well have built that building themselves. They had quite a bit of equipment. We didn't do anything anywhere near the same scale but went and bought, and hauled, our own metal siding, snagged some replaced telephone poles for free, got some lumber that was considered imperfect from the local sawmill (in other words it wasn't purty), and had some folks around who were handy with the right equipment, and got our horse shed put up super cheap. If they did their own labor, they could have probably gotten that built for around $20k give or take a couple-three K, based on what the siding was going for at the time, what the interior looks like, if they have dirt, or concrete floors, if they wired it themselves, etc... I'd not rule out getting the Amish to build it either.
As far back as 2009 there was something, if only a shed, or other trailer, at FR's location. So, I think FR may have either been renting, or the plot lines are just "off" (not uncommon for the latter). FR and KR were really the ones into Derbies w/CR2 getting ready to get into them too from what I've understood.
When FR moved in up the road, and was old enough to drive (He turned 16 in 08/2011), and work, I think he followed in KR's footsteps with the derby cars, the car clutter began to come about and the whole family got into it the fun.
In 2010 the car clutter was pretty much non existent, w/the exception of some around the yellow house, which it is said that KR lived there for awhile. Same for 2012, and up to mid 2013 (based on map data I've found). Then, in 2014 up until the murders, the junked cars started to show up.
I think this is about the time they started to get more into the idea of buying other cars that they were running across, and could fix and turn over for a fast profit under STC. Since nearly all of the males in the family worked for BBL I could see this coming together as a business propostion. DR also wrote about going to the car wash to clean up the cars, and not seeing BH there, and missing him.
Side Note on Properties:
The Camp Creek property was purchased for $8k in 2008 from the man who's property butts up to the UHR properties. Could have been a land contract. 2014 shows a trailer but it is not a new trailer
A sister was Et Al over some of the properties for a period of time, then in April, 2011, all that she was et al over, was then changed over to CR1. The properties have a rather cluttered chain of transfer on some of the pieces. We don't get to see the all of the why's and what ifs though. The property that has the garage on it, to the right of where CR1's trailer is located, was sold to CR1 by TR's M.i.l. (just found that interesting). Not all of the land has been in the Rhoden family for generations. More like just since ole man Rhoden acquired it, and then other land has been acquired throughout time.
