Belvedere LXX is a brand-new condominium on Eckford Street in Greenpoint, Brooklyn, built of burgundy brick. It is so new that its permits still hang in the window, the closets are bare of clothes, and the apartments have yet to hit the market.

So why does it already look so familiar?

This building is part of a growing family of small apartment houses that have sprouted up in Brooklyn over the past 10 years, the majority of which share certain features — a reddish brick facade, about the color of diluted Manischewitz wine; a pair of white columns; and balconies — that make them appear, if not like clones, then certainly like cousins.

Now, as their numbers approach three dozen, most of them concentrated in Greenpoint, there are so many that look so similar that it is starting to feel as if that neighborhood is having a mini, matchy, architectural movement all its own.

“One, two, three, four, five, six,” said Krzysztof Rostek, the developer of the Belvedere LXX, standing on its roof and counting the other buildings he has put up nearby. “You can see six.”
