This is the X-Mansion (aka the Xavier Institute for Higher Learning) built by Glen Bricker. It’s up for consideration right now on the LEGO Cuuso website but I’ve got the feeling LEGO will never go for it. It looks…way too big. Who knows, maybe if it gets enough votes they’ll decide to make the Danger Room part or something. It is stunning, but,..well probably more editions and together they all make the mansion!
