Fan Builds Baxter Building From Avengers Tower Set
Designer MESsemble used bricks from the Avengers: Doomsday LEGO tower to create a Fantastic Four headquarters MOC.
Updated on Oct. 31, 2026 in Comic Books
Fan designer MESsemble repurposed bricks from the Avengers: Doomsday New Avengers Tower LEGO set to build the Baxter Building, the Fantastic Four's headquarters. The build was shared on Reddit and Rebrickable.
Why it matters
The project shows how a single official set can be reused for a different build, and it highlights a gap the designer noted: many Avengers Tower sets exist but no Baxter Building set has been released.
The Avengers: Doomsday New Avengers Tower (76352) has 954 pieces and retails in the U.S. for $109.99, while the MESsemble build's Rebrickable plans cost $3.99 for a total of just under $114. LEGO set 76269, a 5,201-piece Avengers Tower, is priced at $500 and remains available.
The players
MESsemble
A LEGO fan designer known for creating custom models from official sets and sharing them with the community.
LEGO
The Danish toy company that produces the official Avengers and Marvel-themed sets referenced in the build.
The details
MESsemble used bricks from the Avengers: Doomsday tower set to construct the Baxter Building, including interiors and a version of Galactus. The MOC fits into a modular cityscape alongside Spider-Man's Daily Bugle, and the build was shared on Reddit and on Rebrickable.
Timeline
Avengers: Doomsday is scheduled for theatrical release on December 18, 2026.
Culture Shift
The Baxter Building MOC reflects the fan-built MOC culture that Rebrickable has popularized, where designers publish plans and parts lists for community use. It also shows how LEGO's modular building system lets builders reuse official sets for entirely new creations.
Builders who want the Baxter Building design can buy the Rebrickable PDF plans for $3.99 and source bricks from an existing Avengers Tower set. Anyone shopping for a Fantastic Four build now has a documented route to a complete model.
The takeaway
Fan designers can turn a single official set into an entirely different landmark, offering hobbyists a cost-effective way to expand their collections without waiting for new releases.
