Friday Fun? Goff Brook Garage

Now that it's all done but the weathering, the Goff Brook Farmhouse needs a neat little one car garage. Fortunately, there's a kit for that . . .

Much thanks to PeteL for the kit!

 According to the instructions, "this kit was designed to be quick and easy to assemble" and the "unboxing" (well, "unbagging") photo shows all the parts that are included. . .

Unfortunately, that may not be all the parts that are needed. My first clue to this came when I dry-fit the door . . .

Uh oh

I wasn't sure whether the wall was too short (though the mismatch between the top of the back wall next to the side wall should have been a clue), or if the door opening had to be extended up.

So, I took out my handy caliper and started comparing parts . . .

Height of the "door side wall"

Compared to the other/"window" side wall

Note that they're not the same height (off by a couple of clapboards). So I started to check the other parts. . .

Front end wall

Back end wall

 Another mismatch :^(

Corner where front and "door" side wall must meet

Compared to "door" side wall

 And finally (inevitably and most clearly) . . .

I'm pretty sure the corner of the side wall and the corner of the end wall must match - and of course the end walls and side walls must match each other. I'm not being sarcastic - this will/would have been my first laser-cut wood kit. BEST has a great reputation and I've seen their displays at Springfield and such and always wanted to try one of their kits, but this one - the one that was supposed to be an easy introduction - has me flummoxed.

Am I missing something here? Have any of you built one of these kits before? Maybe I just got a mistake-in-production dud?
