Emmet's Modular Dreamhouse




Mix your love of Lego Modulars with your love of the Lego Movie 2 with Emmet's Modular Dreamhouse!

Everything you see here is built using only the pieces from 70831 Emmet's Dreamhouse/Rescue Rocket. You don't need to buy any other pieces. If you've got this set you can build this skinny little modular!

Enjoy the premium 158 step instructions which include options for using either the standard 8x16 plate that comes with the set or a true 8x16 baseplate (not included with the original set).

Check out the video below for full details and walkthrough of the build along with a demonstration of how it fits with other Creator Expert Modulars.

Not all pieces that come with this set exist in Stud.io yet, so I've included photos of the relevant pieces within the instructions to inform the build where necessary.

All three floors easily detach from one another, just like a real modular.

Fits in great with the official Lego Modular sets:

Floors include detailed interiors as well:
Planty and a TV

Ladder to the second floor

Emmet's portrait on the wall

Wildstyle has an Apocalypseburg vibe going on the second floor complete with her binoculars

Wildstyle's portrait hangs on the wall

Unikitty's portrait hangs in the attic

Bay window offers stunning views out the back

Unikitty sleeps soundly in the attic

Rex Dangervest flies overhead

Connects with all the Lego Creator Expert modulars via standard technic pin connection

    What a great concept!  Wasn’t going to get Emmett’s house, now seriously tempted!

    Just finished this MOC - thank you very much :) Fun to build, good instructions, and still has some places where you could add parts or play creatively.  Great! My only wish, that we could have had a trap-door for Emmett to climb into the next storey, but I know there wasn't a piece like that in the selection.

    I like this MOC, I just built it a few days ago, but the tile inventory seems to be wrong? I bought a new set 70831 for this MOC and still have a lot of parts left...??? (Not only 2: The original set has 705 on the list and this MOC has 703 ?)
    But I'm new here, did I maybe misunderstand something?

      Not every piece is used in this MOC. If you have leftover pieces after building, that is to be expected.

    Great MOC.  I bought the set just to build it.  What's the building in the main photo just to our left of it?  The Soap and Suds?  is that a MOC or a set?

      Wow. Thanks!
      The soap and suds is part of the official Brick Bank modular from LEGO.

    Very nice. Fits the theme of Emmet well.  Amazing detail with the parts available, and I love alternate builds, makes it so easy for people to get all the parts at once.

    Nice work! I think the 8-stud-wide modular is perfect for Emmet!
