Looking for instructions to build a hobbit hole without 'custom set pieces'
I have an alternate plan you might consider:


Reference: here's the entry for that set on Brickset
It looks like there aren't many custom pieces used in this set, as seen in the parts list
You could download the actual instructions for the real set, and then just swap out some pieces, removing the color combinations that you don't have


I hope this helps in some small way!
