Actor and New Orleans native Wendell Pierce is probably best known for his role as the cigar-smoking, hard-drinking detective William “Bunk” Moreland on HBO’s critically acclaimed drama “The Wire.” Since the end of that series, though, Pierce has been keeping busy: in between stage performances in New York City and his work on “Treme,” a new HBO drama by David Simon, Pierce has been building affordable, eco-friendly, sustainable homes for a New Orleans neighborhood whose residents were displaced by Hurricane Katrina.
