No SNARLs here, just straight up, tile-covered, right-angled build. Honestly, I have not seen a build that somebody specifically calls a SNARL. We all probably seen many, but I do not know of any who have acknowledged it.
As for the characters' names, I just went to the glossary and tried to mix and match words that sounded "snazzy" together.
UPDATE: Found this wonderful journal that explains it: brickish
