The World-Wide Holdings Corporation is developing a 30-story residential condominium building with large apartments on the northwest corner of Second Avenue at 74th Street.

The tower's entrance will be at 255 East 74th Street.

H3 Architects, of which Hugh Hardy is a principal, is designing the building, which will have 87 apartments.

The lower floors will have loft-like duplex units and several units will have "in-residence playrooms just for the kiddies." "These residences are custom designed for both empty nesters as well as growing families who need more space and crave a wide range of kid and adult-oriented amenities," according to Richard Lebow, director of marketing and sales for the World-Wide Group.

The building, which replaced several low-rise buildings that had popular restaurants, will have a 42,000-square-foot Equinox facility on the ground and second floors.

It will also have more than 2,400 square feet of facilities for "tots, tweens and teenagers, such as a toddler room with a cruising wall, a climbing tree house, a play zone for crafts and a reading area" and a game room "designed for tweens and teens will include an arcade with pin ball machines, extreme dance and basketball arcade games, as well as foosball, air hockey and table tennis" and a "1,500-square-foot outdoor 'Tot Lot' and indoor lounge, kitchenette and party room will also be available."

The building, whose plan has some slight angles, will be clad in glass and metal panels and will be 338 feet tall.

The top floor will have three penthouses and a common roof deck.

The building will have a 24-hour doorman, valet/concierge services, Sub-Zero refrigerators and Miele appliances, 10-foot-high ceilings, Toto toilets, radiant heating in the master bath floors, a private outdoor garden, and some apartments will have fireplaces, balconies and terraces.

Completion is anticipated for late 2008 and prices are estimated to range from $2,500,000 to $7,000,000.
