If you choose to build a new structure from scratch and are sparing about
overall size and design complexity, building
a singe family dwelling, say 16'X32 (12' sidewalls providing 8' first floor
and 4' loft/6-7' ceiling roof: 4/12 - 5/12 pitch)
built using the materials and methods listed above could easily last 100
years, possibly 150 and serve the needs of 4 time the number of original
occupants during its effective lifespan. Building a structure like this
gives you extreme energy efficiency, zero maintenance, maximum durability
and at low cost and considering the number of people who could ultimately
use this structure a very low carbon footprint and minimum pollution.
