Designers Serban Ionescu, Jim Dreitlein, and Justin Smith built The Miner and A Major over the course of five months. The process was iterative. Ideas were sketched out and developed as time and budget allowed. “It was an organic process,” recalls Ionescu. “When we were building it was a strange ritual. We had mattresses laid out in the main room side-by-side and it was like we were camping.”  Photo 2 of 13 in Communal Living on a Budget in Brooklyn
