DOMINIQUE BENZ and her husband are looking forward to hosting a Brazilian barbecue on their downtown Manhattan deck sometime later this year.

Their ambitions for the affair won’t be constrained by space. Last year, the São Paulo couple bought two adjoining apartments at the Caledonia in Chelsea. They plan to combine them, creating a 2,800-square-foot deck — one of the largest private outdoor spaces downtown, brokers said.

Nor will they have any trouble finding fellow Brazilians to invite.

Already, 8 of the 181 condo units in their building have been bought by fellow countrymen, part of a Brazilian buying spree in New York that shows no sign of slowing. The city is already teeming with Brazilian tourists, and many of them, flush with cash from a booming economy back home, are snapping up their own pieces of Manhattan.

While Russians like Dmitry Rybolovlev, the buyer of an $88 million penthouse at 15 Central Park West, boast in press releases about their trophy properties, Brazilians have quietly become steady clients for higher-end brokers in New York and Miami.
