LEGO House 805

Logo: modern logo
Material: ABS
Inner wall: thin with vertical ridges

The wall has ejector pin marks at the bottom.

Inner ribs: None.
Inner tubes: The inner wall of the central tube is less tapered than on the outer tubes.

I expect this is done to ensure that the clutch power of studs connected to the center tube is similar to the clutch power of studs connected to the corners of the brick.

Flowrib / center line inside top surface: No
Mold pip: on the stud
Mold numbers: 805 on the short side.
Mold cavity numbers: 1 to 6 on the short side, separated from the mold number by a dash (-)
Intellectual property protection: (c) LEGO above the right tube.
DesignID: 3001 below the right tube
Remarkable features: Made in a public display at the LEGO House in Billund.
Colors known: Red.

Questions (from Maxx, in the comments):

  • Why did they use a whole new machine/mold for this?
  • What is the mold of the 50yearset with six 2×4 bricks?
  • Have they used this mold before?

I can answer some of those questions 🙂

  • I think they needed a new moulding machine because they wanted to create a display that produces and packages a set. The “6 bricks” have special significance for LEGO. It seems to be inspired by a patent officer who asked: “How many ways can you put together six of these bricks?”, and the answer has been used to demonstrate that the LEGO design (with tubes) is much more versatile than that of their predecessors and competitors.

    This story, related to LEGO history and to what makes LEGO special is very well suited for a display in the LEGO House.


  • The mold of the 50 year set with the six 2×4 bricks is 232.
    The mold of the 50 year book with the six 2×4 bricks is 223.

  • They have not used this mold before. Mold number 801 is being used for production. I think it was the first mold producing 48 bricks in each cycle, so maybe the the 800-series is being used for “special molds”.
