I just noticed this thread. I had the
idea of starting both a Bridgebucket and Buildingbucket a while back, but I had nothing to offer to either. Then, last year, I started making a skyscraper in SB scale and style, but wasn't sure if it was worthy yet to go on the forum. More recently, after getting back on my proper home laptop for the first time in ages, I've decided I'd like to start a standard SB-scale unified Buildingbucket thread ASAP, posting that building as a WIP.
I just thought I'd throw that out there as an FYI. If/when I start my own Buildings thread, I'll let you know so we can distinguish them in our titles and maybe even collaborate a bit. It looks like yours is exactly twice SB scale, which is definitely better for the smaller local structures you seem to be dealing with.
Cheers
