“As a prototype for future Big Dig architecture, the structural system
for this house is almost wholly comprised of steel and concrete from
Boston’s Big Dig, utilizing over 600,000 lbs of recycled materials” [source].
With the future of Big Dig in trouble, probably this project may not last long too or rather, if the Big Dig is entirely scrapped, we might have plenty of such houses popping up. I’m just not sure if that is a good thing.
