The Landmarks Preservation Commission is expected to review an application to erect a 7-story, torqued, structural "net," rooftop addition to a two-story commercial building at 837 Washington Street in the Meatpacking District at its next meeting Tuesday.

The proposed addition has been designed by Morris Adjmi and renderings indicate that, if approved, it may become one of the striking building designs not only in the Meatpacking District and Chelsea but the city.

It is closest in spirit to Frank O. Gehry's wave-inspired building several blocks to the north on West Street for Barry Diller's I.O.C. company that is just to the south of Jean Nouvel's taller curved residential condominium tower with its random fenestration patterns in which different size windows have different angles.

The proposed rooftop addition, furthermore, is very close to the recently glass-enclosed rooftop addition to Diane von Furstenburg's shop and it is across the street from the bent new Standard Hotel that straddles the High Line Park. The city's newest spectacular skylight can be found atop Diane von Furstenberg's emporium at 874 Washington St., between 13th and 14th streets. The large, prismatic skylight is at the southeast corner of the building, the culmination of a four-story, high-tech staircase. It was completed about two years ago by Work Architecture Co., of which Amale Andraos and Dan Wood are principals.

The proposed Adjmi addition for the building on the southeast corner of West 13th Street bears a similarity in its twists to a stunning 54-story skyscraper in Malmo, Sweden designed several years ago by Santiago Calatrava that was a precursor of his celebrated but apparently aborted designed for 80 South Street that was not "torqued" but was to have had a very tall stack of 10 four-story townhouses in the sky just south of the South Street Seaport.

Adjmi's curves are not as sinuous as Gehry's 8 Spruce Street apartment tower nearing completion near City Hall.

Indeed, they are much tamer than Gehry's spectacular Solomon R. Guggenheim Museum in Bilbao, Spain, and his concert hall in Los Angeles, but they are quite impressive by New York City's standards.

The developers of the Adjmi project are Taconic Investment Partners and Square Mile Capital, who acquired the existing 1938 building from the estate of the late Robert Isabell, a well-known floral designer and party planner, who died in 2009.

Adjmi design encloses glass-enclosed offices behind an angled steel gird. It was presented recently to Community Board 2's landmarks and public aesthetics committee that, according to a report at curbed.com, like its creativity but felt it was too "tall."

"Planter boxes ring the new building at each floor, softening the hard lines and offering an homage to a plan that Robert Isabell hoped to build after he bought the 1938 market building for $45 million back in 2008. When the High Line opened in June of 2009, Isabell saw to it that the old metal canopies ringing the base of his building were planted with a profusion of flowers, offering park-goers a colorful vista across Washington Street," according to ny.curbed.com.

Mr. Adjmi has designed the Scholastic Building on Broadway south of Prince Street and 40 Gansevoort Street and 450 West 14th Street.
