Honcho house lawsuit

Nothing destroys a friendship like the botched renovation of a $10.5 million Manhattan town house.

Goldman Sachs honcho R. Martin Chavez slapped interior designer and former pal Aaron Kirsten with a $5.1 million lawsuit for failing to complete an overhaul of his five-bedroom, 4,300-square foot spread in the Village.

Chavez, 49, purchased 60 Bethune St. in 2011. The house was in “white box” condition, meaning it lacked a finished interior, according to court documents. The Goldman exec envisioned an elaborate dwelling.

Kirsten, 41, counters that Chavez’s unrealistic unwillingness to pay for what he wanted sank the project, according to e-mails included in the Manhattan Supreme Court lawsuit.

Kirsten told The Post that Hurricane Sandy ruined him and that he would like to “make amends” with his former friend.
