That still looks like it would be expensive to do an entire building. But it is the best technique I have seen for doing realistic siding. “Snoting” refers to the use of the SNOT (“studs not on top”) building technique. This is a popular acronym dating back at least 15+ years in the AFOL community (along with BURP – “big ugly rock piece” – and POOP – “piece out of other pieces”).
