Can you build a house with LEGO?

Normal concrete has a typical strength of about 15 MPa, while high-strength concrete, commonly used for buildings of considerable height, can support an average of 70 MPa or even 100 MPa.

In the attached GIF, it is evident that LEGO bricks can withstand a pressure of about 75,000 kg before showing signs of deformation. It should be noted that even if no obvious breakage occurs, the pressure causes an increase in temperature that leads to the melting of some plastic bricks.

It is fair to say that LEGOs can withstand a pressure of about 6 MPa. However, this strength is significantly lower than that of ordinary construction concrete, accounting for less than half.

It is important to note that building a house out of LEGO is not only limited by the resistance converted to pressure, but involves multiple factors. The difficulty lies not only in the strength of the material, but also in considerations related to structural, thermal, and safety factors that require specific materials and construction techniques to ensure the strength and safety of a housing structure.
