After a two-year, $170 million expansion and renovation that was 10 years in the planning, NorthPark, that grand old lady at the northwest corner of Northwest Highway and Central Expressway, has survived her facelift. Overseen by Nancy Nasher and David Haemisegger, the daughter and son-in-law of NorthPark developer Raymond Nasher, the expansion of Dallas' first great large-scale mall now includes a pair of new parking garages, a 200,000-square-foot Nordstrom, a new AMC movie theater, 110 new stores in 260,000 square feet of new two-story space and a 1.3-acre garden called CentralPark. The renovation and additions maintain the sleek integrity of NorthPark's original design and don't deviate from the use of clean lines, modern architecture and signature cream-colored East Texas brick and polished concrete floors. Nasher's devotion to putting art in public spaces continues to provide NorthPark with eye-pleasing sculptures. Even with the noisy new food court (NorthPark's first), the 41-year-old mall is still airy and elegant. Hitting middle age, the lady's looking better than ever.
