A new lawsuit has brought a skirmish over a residential skyscraper on the Upper East Side to new heights.

State Sen. Liz Krueger, City Councilman Ben Kallos, and two neighborhood groups are challenging the city’s approval of a residential building with an art gallery, currently under construction at 180 East 88th St.

DDG Partners’ structure is slated to rise 524 feet, when including mechanical equipment.

In a lawsuit recently filed in New York County Supreme Court, the Upper East Side groups claimed DDG Partners created a micro-lot to skirt zoning rules that would have otherwise limited the building’s height to about 300- to 350-feet, according to estimates from Kallos’ office.
