The owner of a 114-unit mixed-use building in Astoria is seeking $100 million for the property.

Development and construction firm Mega Contracting Group purchased the site at 31-57 31st St. when it was a parking lot in 2015 for $17.35 million, according to city property records. It then built a rental building, along with retail and community facility space and a below-ground parking garage.

Last year the firm leased 11,000 square feet of community space at the building to a preschool.

Mega Contracting has hired a sales team from Cushman & Wakefield led by Bob Knakal, Cushman's New York chairman of investment sales, to market and sell the seven-story property. Enhancing its value are lucrative tax breaks it received. The building secured 421-a benefits without having to include any affordable units by partaking in the state-authorized program before it was reformed last year.

It also received benefits from ICAP, a program which grants developers large tax savings on newly built commercial spaces.

Knakal said the property would be attractive to investors because few newly-constructed buildings have hit the market recently in Astoria, an area that he said has a more quaint feel than Long Island City, a neighboring area now filled with high-rises.

"Astoria has a real neighborhood feel to it," Knakal said. "We expect this building to be sought after."

Cushman sales executives Stephen Palmese and Hall Oster are working with Knakal on the sale.
