I am really not good at developing my own designs, but I managed to do this. From a single set: Roy Toy's natural wood Earth Friendly 250 piece bag.
First I built the design buildings for the set (bottom image), then after an overnight break, dumped the big bag of parts out into a box lid. I played for a while with how they might go together. I got frustrated several times by not quite being able to work out how to do something.
At some point, I am going to make a few pieces of my own - from raw stock, and by adding notches to some of my extra pieces.
For me, one of the good things about Roy Toy is that the quality & consistency are not so excellent that my own unexcellent work can't fit in. ;)
First, though, I thought I should accept the challenge of seeing what I could create just with what came in the bag, as-is.
I actually enjoy the mild roughness and occasional flaw. It is made by real people without over-automation and strict quality control.
Sometimes you have to turn a piece over or swap an "identical" piece to get a better fit. But that's life in the big woods. Consider it flavor, not spoilage.
The most critical measurement for satisfactory construction is consistent notch spacing, and here Roy Toy does very well.
The chimney and doorsteps (flat beach rocks I picked up Friday) were forgotten as I finished up the house & took pictures. Consider that flavor, not spoilage, as well, please.
I actually started out thinking I would have two stories for at least part of the building. I can do that by mixing in my other uncolored Roy Toy. In the fullness of time.
This bag actually had a few more than 250pieces. The large image near the bottom of this post shows the buildings on the instruction slips (unfortunately tiny in my set, but recently replaced by a larger, improved sheet), with the parts I had left over in front.
The parts I had left over from today's house are at left . There are a bunch more medium length notched logs in the bag at left rear. I dump the common and easily distinguishable parts loose into the big bag, and sort out the similar & special parts into a couple of plastic bags that then go in as well. Sort of a compromise between übersorting and a complete mishmash.
Roy Toy also has a 250 piece bag with colored pieces, presumably having roughly the same parts mix, since it builds the same three (four) buildings. Well, the cabins shown for the two sets are different, but neither is the same as the one in the set I got, and it is "half way between" the two shown.
Creative endeavor. Good Block Play.
Addendum: I received today, by email from Roy Toy, an improved full-page instruction sheet (noted in revision above), which should make building the standard structures much easier. [11/16 14:41]
