The London architecture firm is working with the European Space Agency to investigate methods for constructing lunar homes and has designed a four-person residence that would shelter its inhabitants from dramatically changing temperatures, meteorites and gamma radiation.


The idea...
The base of the house would be unpacked from a modular tube and an inflatable dome would fold up over it. Layers of lunar soil, known as regolith, would then be built up around the frame using a robot-operated D-Shape printer, creating a lightweight foam-like formation that is derived from biological structures commonly found in nature.
Well and good. But before you go the the moon, Norman, how about finishing that building you promised Seattle five years ago...

The hole is still there.

UPDATE:
Looks like the hole will not be there for long.
