Buying in a New Development?
New construction works differently than a resale: offering plans, sponsor contracts, closing costs and timelines all have their own rules.
A Closer Look at the Building
122 3rd Place keeps its 1899 brick facade, front garden and brownstone-finished stoop, with a new steel and block extension at the rear. Residence 2 is the upper duplex: 2,218 square feet with four bedrooms and three baths, ceilings around 9'9", wide-plank oak floors, and a kitchen with Douglas fir cabinetry and Caesarstone counters. The primary bedroom opens onto a 206 square foot terrace, and a private stair leads to a 333 square foot roof deck with Manhattan skyline views, for 539 square feet of private outdoor space in all. Heat pump heating and cooling and an in-unit washer and dryer round it out. It's a walk-up.

Carroll Gardens Highlights
Carroll Gardens is one of Brooklyn's most tightly held brownstone neighborhoods: tree-lined blocks with deep front gardens, an Italian-American history that still shows up in the bakeries and shops along Court Street, the restaurant row on Smith Street, and Carroll Park at its center. The building stock is small-scale, so new condos here are rare.
The F and G at Carroll Street, about a 3-minute walk
The D, N and R at 4th Avenue and 9th Street, about 14 minutes
Smith Street, Court Street and Carroll Park, all close by
Katie's Take
I track every new development in Brooklyn, and here's how this one compares: at about $1,711 a square foot, Residence 2 asks less per foot than most of the new Carroll Gardens condos I'm following, where 62 4th Place, 361 Union Street and 420 Court Street run about $1,900 to $2,150. It's also the only one with four bedrooms on two floors plus a private roof deck. With the garden home closed, this is the last chance to buy new in this building.
