DENVER-A touch of the Big Apple is coming to Stapleton, the former international airport that Forest City is redeveloping into a 4,700-acre, mixed-use development. The project eventually will have three million sf of retail, 10 million sf of office/research/development and industrial space, as well as 12,000 homes and apartments.Touchstone Homes LLC, a local developer, is about to kick off sales of the urban-looking Denver Brownstones at Central Park. The units will range in size from 3,500 sf to 3,650 sf each and will be priced in the $800,000s and $900,000s. The Brownstones, designed by Godden/Sudik Architects, take their design cues from historic mansions built in New York City in the 1920s. Amirob & Associates of Denver is the interior designer of the units, which will have two floor plans, the Manhattan and the Park Avenue. Forest City requires all of the residential units to meet Built Green, or environmental and energy sustainable, standards. Jennifer Gore Unlimited will market the units.In keeping with the New Urbanism design of Stapleton, the units will be in walking distance to public schools, shops, restaurants, services, transit and a park. The units will be built around an 80-acre park, which Forest City is calling Central Park. EDAW Inc. is designing the park, which will include an urban forest, prairie mounds, promenade, open grass areas for soccer and picnics, and a stage surrounded by seating for concerts and lectures."Touchstone's homes at Stapleton blend new technologies for communications and resource efficiency with traditional architecture and neighborhood design," says Dan Mues, general manager of Touchstone.
