Hollywood studio boss Scott Stuber and Molly Sims are suing their ultra-luxury Hamptons and LA home designer, Dan Scotti, for $1.4 million, Page Six Hollywood has learned.

Stuber and Sims claim Scotti fogged up their dreams of a fully custom-built Hamptons house with improperly installed windows in a case that’s been tied up in Suffolk County court. 

The power couple alleges in court papers filed in Long Island that they hired Scotti — who’d previously worked on the duo’s Pacific Palisades home, as well as a prior East Hampton spread — for a fee of $1.25 million to “design and construct a single-family residence… with an attached guest house and associated improvements, including outdoor pool cabana, swimming pool, and sports court.” 

A 2022 Architectural Digest feature on the couple’s dream home sunnily said, “Happiness is meant to be shared, so in 2018 the couple purchased a piece of land in Sagaponack, New York, to build a dream home with plenty of room for friends and family to come visit.”

“Step Inside Molly Sims’s Fully Customized Hamptons Beach House,” was the headline to the piece, which extensively quoted Scotti as well as Sims, and said the home “blends quintessential Hamptons shingle-style architecture with sleek modernism.” 

Leading a series of dazzling pics in the AD spread — Sims was photographed smiling and pouring rosé on a patio in front of endless floor-to-ceiling windows.

The home was also featured in a number of other magazines, and Sims said, “it’s a dream come true.”

But behind the scenes, the couple’s rosy view of their luxe property became less clear — literally.

Court papers allege that the home’s custom floor-to-ceiling windows were wrong and installed improperly via Scotti and a subcontractor, and in 2022, “Plaintiff’s property management company discovered condensation appearing on the inside frames of the windows in the Home.”

The couple alleged in court docs, via an LLC, that on a call about the issue, Scotti, “Acknowledged that ‘condensation has been forming on the bottoms of some of the window units when the outside temperature drops to super cold levels,” and that while Scotti installed numerous “dehumidifiers,” to try and clear up the problems, “the condensation issues still persisted and persist.”

The suit alleges, “The use of inadequate windows, as well as the improper installation of the windows, individually and collectively caused building envelope defects in the Home.”

Translation: A ‘building envelope’ refers to the barrier between the interior and exterior of a building.

Says the suit, “Due to the building envelope defects, the windows in the Home must be replaced with new windows that are properly engineered, designed, manufactured and installed to be suitable for the normal climate conditions encountered in Sagaponack, New York.”
