These days, high-end Manhattan condo conversions are as quotidian as eight-figure listings. But with soaring prices for properties in Brooklyn’s leafier neighborhoods, some of the borough’s pre-war multi-family rental buildings are getting Manhattan-style makeovers.

In Park Slope and Carroll Gardens, the Manhattan-based developer East River Partners is currently buying up and gut-renovating non-rent regulated multi-family buildings throughout the area. In the past year and a half, the firm has scooped up three multi-family buildings in Park Slope and one in Carroll Gardens. The company is in the process of transforming the buildings into 900- to 2,000-square-foot, two and three bedroom condominiums — units designed to lure Brooklyn’s Bugaboo stroller-pushing set.

Daniel Goldstein

A leader of the opposition to the Barclays Center may have officially lost his battle when the arena opens later this week, but he appears to be on the winning side of a more local real estate battle.

Park Slope neighbors have finally relented in their efforts to thwart Develop Don’t Destroy Brooklyn founder Daniel Goldstein’s plans to build a three-story extension to the back of the home he purchased last year. Goldstein bought the property last year after winning a $3 million settlement when his Atlantic Yards home was seized to make room for the Forest City Ratner development. [more]

Triangle Sports building and TerraCRG’s Geoff Bailey

The legendary Triangle Sports building, located on a three-sided parcel at 182 Flatbush Avenue, across from the Barclays Center, was sold to Redsky Capital for $4.1 million, the Brooklyn Paper reported. The building had been on the market since January, when store co-owner Henry Rosa enlisted Geoffrey Bailey, director at brokerage TerraCRG, to find a buyer.

The purchaser is a group headed by two 2006 graduates of Cornell University, Benjamin Bernstein and Benjamin Stokes, that has amassed a portfolio of 170 Brooklyn apartments and six-figures of commercial square-footage. But they paid a hefty price for this acquisition. [more]

On Prospect Park and SDS Procida’s Mario Procida

Owners of condominiums at the Richard Meier-designed On Prospect Park filed a more than $200 million suit yesterday in Brooklyn state court against developer SDS Procida Development Group and other companies involved the building, the New York Post reported.

The suit alleges that the building still lacks a certificate of occupancy nearly four years after move-ins began and that its temporary one expired a month ago. As a result owners can’t refinance their mortgages or sell their units and fail to meet other mortgage and insurance requirements. [more]

Forest City Ratner’s MaryAnne Gilmartin and a rendering of the tower

Eighteen months after Forest City Ratner began publicly considering using modular construction to build the first residential tower at Atlantic Yards, a final decision is nearly in sight. The firm is building a prototype module this month and will decide by Christmas whether to employ the prefabricated method for the 32-story, 930-unit tower, Crain’s reported. If built, it would be the largest prefabricated structure in the world. [more]
