Looking for old Lego Modulex architects M20 bricks


I'm looking for architects and firms that may have used the Lego Modulex system in the 1960s and 1970s for models. It was also known as M20 (since it was 1:20 scale). If you have any in an old storage closet (or know someone who might), please let me know. I'm trying to acquire as much as I can (will buy it from you) for some large models I am building.

For more info on what I'm looking for, see here:

Thank you,

Hi Karyn.
Are you still looking for Modulex bricks?
I have about 10.000 pieces in different colours, shapes and sizes in Copenhagen.

Best regards

Very nice. How much?


I don't know, I might put it to auction, but it's still not decided. An auction house said in would go for 900-1200 € and possible even more if a collector comes around. It's very unique so I just want the right person to have it, it should be kept intact and not sold piece by piece....

Ok but you can’t live in it unless you find a huge amount of bricks for sale, and a gigantic stack of money..... ;-)
