On Sunday, make time to see this splendid eight-room co-op at 1100 Park Avenue in Carnegie Hill.

Open House Weekend Report: March 1-3

Get up close and personal with Corcoran during one of our favorite home tours in New York City, the Hamptons, and South Florida.

Have plans for the weekend? You do now. Wherever you are—in the city, out on the East End, or catching some rays in South Florida—put a Corcoran open house on your calendar. Among this week’s picks, a sprawling Carnegie Hill co-op with a 60-foot-long private terrace, a Park Slope condo in the old Ansonia Clock Company factory, and a century-old Gothic castle—yes, a castle—in Southampton Village.

Manhattan

2150 Broadway, Apartment 10D, Upper West Side

Sunday, 11 a.m. to noon

2150 Broadway, Apartment 10D, Upper West Side

What’s here: Priced at $6,995,000, this seven-room, 2,701-square-foot condo features four bedrooms, three and a half bathrooms, a gourmet kitchen with appliances by Viking and Sub-Zero, and a Creston smart-home technology package.
What we love: The creators of the graceful Laureate condominium — which includes 69 units on 20 floors — claim the new building is “built to prewar standards.” To study this apartment’s fine proportions and see its fastidious attention to detail, it’s a surprisingly easy claim to believe.

1100 Park Avenue, Apartment 16B, Carnegie Hill

Sunday, 1 p.m. to 2 p.m.
Viewings by appointment only.

1100 Park Avenue, Apartment 16B, Carnegie Hill

What’s here: Priced at $6,950,000, this eight-room co-op — with interior styling British interior designer Caroline Weston and New York-based Jennifer Cohler Mason — features four bedrooms, three bathrooms, and a 60-foot-long private terrace.
What we love: 
The term “great room” is pretty common, but rarely is a great room as great as this one, with a lofty beamed ceiling, wood-burning fireplace made of Azul Valverde limestone, and skyline view from floor-to-ceiling windows.

Brooklyn

444 12th Street, Apartment 4E, Park Slope
Sunday, 2:30 p.m. to 4 p.m. 

444 12th Street, Apartment 4E, Park Slope

What’s here: Priced at $2,025,000, this six-room, 1,600-square-foot condo features three bedrooms, two bathrooms, and, for an additional $175,000, a deeded parking spot.
What we love: There’s no denying that old factories make great apartments: Opened in 1881, this sprawling building was the second Ansonia Clock factory on this site (the first one burned to the ground in 1880), and today, the 70-odd residences in it feature huge windows, high ceilings, and a great backstory.

What we love: It’s a castle, built in 1911, with all kinds of olden-days castle goodies throughout — a four-story tower, crenelated red brick walls, tracery windows, and more.
The agent: Robert Lohman
