For those who don't want to see the Youtube link, please describe these hexagonal living units in more detail or provide a transcript of the video here (Youtube videos usually include transcripts).
Each hexagon is 10,000 sqft and 3 stories tall. You can build whatever you would like in this space using traditional residential construction methods.
Most of my designs have 16x22 foot bedrooms which open up into larger shared areas, usually with 20 bedrooms per hexagon.
Hexagons can be split into 10 bedroom trapezoids (half a hexagon) or 6 bedroom rhombuses (1/3 a hexagon)
If you feel the blueprint is too crowded, you can convert bedrooms into misc rooms until you get to a nice crowded/affordable mixture.
Total cost of construction is still an unknown, but estimates are as little as $250/bedroom at current interest rates. If interest rates go back down to 3%, we could achieve profitability at only $150 per bedroom.
