There's a great documentary online, on most documentary websites and YouTube, that talks about this project.
- Link?
  
  Not who you asked, but I found this, which might be the one.: https://youtu.be/znmZeEycRwE?si=T0v3FHdJe4oFndgN
  It's an hour long and has the BBC logo at the start so it should be decent at least. Not watched it yet, but I will be :-)

That’s not the size of small city.
Edit: apologies. I don’t think that hit quite like it meant to. I’ll delete the offensive part because it doesn’t really sound very nice.
- The biggest design above is the "super" Orion design; at 8 million tons, it could easily be a city.[25] In interviews, the designers contemplated the large ship as a possible interstellar ark. This extreme design could be built with materials and techniques that could be obtained in 1958 or were anticipated to be available shortly after.
