As impressive (and desirable) as LEGO 's 2,500-piece DC Comics Super Heroes Batman: Classic TV Series – Batcave may be, it's dwarfed by this mammoth 18,000-brick fan-built Arkham Asylum.

Built for Brickvention 2016 in Melbourne, Australia, it took LEGO enthusiast Dayton more than a year of planning and three months of actual construction.

"I feel this was the milestone for me as a builder as this is something I have wanted to build for years now and I am so happy with how it turned out," he wrote on Flickr. "Almost everything I wanted to put into the moc was built and included."

Dayton's Arkham boasts five rooms, including a maximum-security level with seven cells (with lights, naturally). "The whole interior turned out pretty good," Dayton said, "and I really like what happened the whole roof and clock part of the building. "
