John Mellencamp's lake house near Bloomington, Ind., was so shoddily built that parts of it had to be torn down and done over, the singer contends in a lawsuit against the builder.

Homebuilder Timothy Eldredge and The Eldredge Group fraudulently used cheap materials, submitted fake invoices and kept proceeds of discounts that should have gone to Mellencamp and his wife, according to the lawsuit filed Tuesday in Indianapolis.Mellencamp is seeking unspecified triple damages.
