It's less a matter of technical capability and more one of cost. It's not like people didn't know how to build good, efficient homes before. It was just expensive.
We have absolutely made strides in material technologies for construction over the last 50 years. Take asbestos for example.
Asbestos has some pretty insane properties, though. Just a shame it causes cancer when disturbed and inhaled.
As a building material? What's even better than asbestos in terms of the trifecta of sound/heat isolation, bulk, melting point, and structural soundness? Aerogel?
Not just that but internal insulation and fireguarding has come a long way.
