I think it can be a fun practice when someone takes an official LEGO set and puts an entirely new (or old) twist on it. This Classic Space version of 10251 Brick Bank released in 2015 built by Justin Winn is just the kind of thing I’m talking about. Its façade is easily recognizable as the bank, but has all the classic colors and vibe of the retro-space and M-Tron themes. I’d love to see this idea applied to the entire modular series!
Justin’s Classic Space Brick Bank has a full interior, with a vault and plenty of old-style computer terminals.
This isn’t the first time Justin has “spacified” an existing LEGO set! Check out his customization of the 10196 Grand Carousel!
