Housing is one of the most important, most expensive things that humans need.

An estimated 1.6 billion people - one-fifth of humanity - lack access to adequate housing and basic services, according to a recent report by the UN in 2024.

Existing attempts to solve the housing crisis have failed to solve the problem. Approaches meant to solve the problem, like 3D printing of homes with various mixtures of concrete, or prefab homes, remain far too expensive and out of reach for most people.

Homes are also incredibly complex to build from scratch, requiring a large team of specialized contractors, expensive equipment, and many strong laborers.

Where is the ultra-affordable, hyper efficient, passive solar home that can heat and cool itself with very little expense, that’s delivered in easy to move blocks that are simple for almost anyone of average strength to assemble, like a life size set of LEGO blocks?

There have been a few companies that have tried this with just the walls, but that leaves the homeowner still having to hire contractors for electrical, plumbing, septic, windows, doors, exterior and interior wall surfaces, and concrete work.

Where are the human sized Lego blocks to build a home with snap together plumbing, electrical, doors/windows, roof, floors, and finished walls?
