It's big—11 acres.

It's expensive—$500 million.

It's complicated—98,000 square feet of retail, 300,000 square feet of commercial space, and at least 600 units of housing.

But most of all, Justison Landing, under construction on the banks of the Christina River in Wilmington, Del., is a sign of the times.

“This is an exciting time for Wilmington,” says Rob Buccini, cofounder of developer Buccini/Pollin Group, whose roots are in the city. “Never before in the history of Delaware has so much construction taken place.”

Buccini is turning Wilmington's former shipbuilding area into a live/work/play environment that caters to young professionals, empty nesters, and a small percentage of families.

“Our project is within walking distance of 15 million square feet of office space,” Buccini adds.

Even though it's new, Buccini wanted Justison Landing to fit in. He hired Anton Germishuizen, director of the Philadelphia-based architecture firm Burt Hill, to design a project that melded into the area but still had its own personality.

Germishuizen says he accomplished this by borrowing from Wilmington's brick buildings, emphasizing the open space and waterfront, and using different looks for different buildings.

“We wanted to mix up the styles for more texture,” Germishuizen says. “We don't want it to look like the design was done by a single hand. There is a richness about it this way.”

The project broke ground last June, and the first phase is set for completion in late 2007, Buccini says, adding he sold 18 percent of the units during presales.

The Brauser Group is developing 100 West 18th Street, a 41-unit condominium community in East Chelsea, N.Y. The 10-story building, clad in iridescent black brick, will offer one- to four-bedroom units with white oak floors, stainless steel and glass range hoods in the kitchens, floor-to-ceiling limestone master bathrooms, and iPod docking stations in the master bedrooms. Amenities will include a landscaped roof deck with an outdoor shower and gas grill, club room with kitchenette, Zen garden, fitness center, and 24-hour concierge service. Occupancy is scheduled for January 2008.
