“Builder” to the stars Ben Krupinski, who has crafted the Hamptons homes of Martha Stewart and Billy Joel, is at the center of a bitter family feud with his daughter Laura — who astonishingly accused him of having an affair with Martha.
Page Six has exclusively learned that Krupinski, 66 — worth an estimated $150 million and who counts business moguls Steve Cohen and Leon Black among his clients — has cut off 47-year-old Laura from her $26,000-a-month allowance and thrown her out of a family-owned mansion in Bedford.
Former Wilhelmina model Laura says the family feud started over Ben’s relationship with the domestic diva behind the back of her mother, Bonnie, his wife of more than 40 years.
Laura said, “I had a difficult relationship with my parents for years; I had breast cancer three years ago and my father didn’t call or come to the hospital. I saw my father and Martha together on the beach one morning in Palm Beach a few years ago. It was obvious something was going on.
“I held it in for years, but finally told my mother what I had seen in March this year. Dad denied it and said I was crazy. My mother got angry and wouldn’t return my calls. My dad cut off my monthly allowance in April and kicked me out of the Bedford house. They took away everything I own — all my clothes, even my wedding china.
“Dad told me he hated me and never wanted to see me again. We haven’t talked since.”
Ben didn’t return calls for comment last night, but a source close to him said, “The family has supported Laura financially for 47 years, but she has some personal issues. They hope that she can get some help to subdue her demons.”
Robert Lin, attorney for Krupinski, said, “This is a sad situation. They are worried about Laura and they hope she can do something to help herself.” A rep for Stewart said, “Martha has absolutely nothing to do with this situation. She is good friends with Ben and Bonnie. ”
Laura added, “They have tried to do everything to hurt me. They paint me as horrendous, I am their only child. There is no love; all they care for is money. I have no demons except my parents.”
