Ginsburg Development Group of Valhalla, New York, has commissioned 1100 Architect to design a 12-story, 19-unit, residential condominium building at 241 West 19th Street between Seventh and Eighth Avenues in Chelsea.

1100 Architect is headed by David Piscuskas and Juergen Riehm and has offices here and in Frankfurt am Main. It designed the new building for the Little Red School House and Elisabeth Irwin High School building in Greenwich Village in 1999 and 2002.

Construction on the 19th Street project is expected to begin this month.

The building will have 14 two-bedroom units ranging in size from 1,070 to 1,197 square feet, four penthouses ranging in size from 1,516 to 1, 854 square feet and a duplex garden apartment with 1,256 square feet. The building will have a fitness center, a bicycle room and private storage space. Kitchens will have Bulthaup cabinetry, Sub-zero refrigerators and Bosch dishwashers. Windows will be floor-to-ceiling and ceiling heights are 9 feet.

Apartments are expected to be priced from about $1,250,000 to $2,995,000.

Ginsburg recently acquired the property for $13.5 million from West 19th Street Development LLC. The site, which was formerly occupied by a four-story commercial structure and a three-story residential structure, was delivered vacant to the buyer.
