Lego Modular Space Museum


Last Updated . Click "Updates" above to see the latest.

Dear ladies and gentleman, I proudly present the Lego Modular Space Museum. Like many of the Ideas community members, I too became hooked on Lego as a child. My favorites at the time (80s) were the Space and Castle themes. Don’t tell the castle sets I said this but if I had to choose I would reach for Benny. :) This build serves 3 purposes- 1) Homage to the Space sets, 2) I wanted to build a Modern Building, and 3) I wanted to do a Modular build (this is my first humble attempt). Additionally, I wanted to make this build fully accessible without having to remove floors (I personally dislike that- I want to play with the set as the whole model not in separate floors). I achieved this by using hinged wall segments. The Museum is fully accessible and stays completely intact via clips. Oh, and what museum is complete without a 2-story waterfall feature?




32x48 Dots- 32x32 baseplate + 16x32 baseplate.

10 inches x 15 inches x 9 5/8 inches tall (building itself).

18 inches at its tallest point.

2787 Pieces.

Fully compatible with Lego Modular Buildings, connects via Technic pins.

10 Minifigures- 4 in displays and 6 for play including 2 employees and 4 museum visitors (more specifics found below in the exhibit/feature section).


The Lego Modular Museum has many unique exhibits and features:

Thank you for taking the time to visit this project. I took many pictures throughout the build and of the individual displays and all the minifigures, so please check them out- I will include all of them in an initial update. I really enjoyed this build and feel it would be a great addition to any modular city or as a stand alone set. If it’s something you like please support so that we may reach 10,000 and make this set a reality! Also, please share it with your friends and on social media to get the word out...
