The Grand Prospect Hall, the over-the-top Park Slope event venue, was sold in a $30 million deal involving 12 neighborhood properties, according to The Real Deal.

The reception hall was sold by owner Alice Halkias for $22.5 million to Gowanus Cubes, an LLC operated by Angelo Rigas. Eleven other parcels made up the remaining $7.5 million of the deal.

Halkias and her husband Michael, who passed away last year, were the stars of their homespun commercial—set to soaring music (and parodied by Saturday Night Live)—promoting the hall's glamorous spaces, with Alice Halkias declaring, "We make your dreams come true!"

The four-story Victorian structure, built in the late 1800s, was entered into the National Historic Register in 1999 as having social and cultural significance, with its late 19th-century revival of French Renaissance style and huge theater, "arranged and decorated in the tradition of America's great 19th-century ethnic halls."

The Halkiases decorated the hall with remnants from other buildings—14 of the hall's crystal chandeliers were from a Greenpoint church, while another in the front entrance area was from the original Loew's King Theater; columns that were originally thrown in the trash; ceiling tiles from shuttered eateries. In 2015, Michael Halkias told Gothamist that he received offers from developers to turn the hall into condos every day, "I get letters, I get phone calls."

The Real Deal reports that the properties total 73,104 square feet of built space, "Controlling the assemblage gives Rigas, an electrical contractor, the option of constructing a substantially larger building at the address... His father, Gregory Rigas, built several projects in the area, including the 80-unit rental tower 574 Fourth Avenue, near 16th Street."
