Why not build a prefab almost entirely out of reclaimed materials? That’s what Reclaimed Space founder Tracen Gardner wants to do. Mr. Gardner was in between contracting jobs and began constructing a portable building using primarily reclaimed materials. In the process, he liked what he was doing so much that he decided to create Reclaimed Space to continue building modular, passively-designed cabins. To start off with, the company will build spaces from 240 square feet and at prices in the range of $115 to $160 psf (min. $25k).
