FIDI KEEPS PERKING UP

District: With Amy Sacco as its “lifestyle consultant,” the 163-unit District could have a pretty sweet scene. There’s a 12,000-square-foot rooftop terrace with lighted reflecting pools, chaise lounges and cabanas, an indoor pool, a spa, a screening room and a lounge/library with billiards. And if the scene is sputtering, there’s a concierge on duty 24/7. Opening September.

Dwell on Wall: Designed by Philippe Starck, this just-opened 507-unit rental has your typical amenities – 24-hour doorman and concierge, gym, penthouse lounge – and some atypical ones too, including on-site parking, free breakfast and automatic rent payments via your AMEX.

Nobu Hotel and Residences: Well, you can be assured that the restaurant here is going to be an upgrade for FiDi. The 62-story, all-glass condo-hotel (with 77 residences) will have a Nobu on the third floor, a six-floor-high atrium with retail space, a screening room, a 13,000-square-foot health club and spa with an indoor pool and the all-important private sake cellar. Occupancy: 2010.

The Setai: If it’s anything like Miami’s Setai, this 167-unit building could single-handedly make FiDi a cool place to live. With 44,000 square feet devoted to amenities, residents will have access to a members-only Setai club, restaurant, spa and rooftop terrace with hot tub. Other perks: room and maid service, butler service and in-room spa service. Occupancy: Fall 2008.

William Beaver House: The 320-unit building’s ad campaign has morphed from sexy cartoons to pillow fights among nubile young women, so we’re pretty sure it’s favoring single-guy buyers. Or voyeurs, because you will be able to use the Internet to see what’s going on in your apartment from anywhere in the world. Other amenities: a restaurant, lounge with wet bar, lap pool, screening room, covered outdoor dog run, sundeck and “sky lounge.” Occupancy: Fall 2008.
