Interestingly, Sandridge isn't bulldozing its way to success - most of the existing properties will be preserved.
Greg Lindsay writes, "The plans include a renovated 1960s tower by architect Pietro Belluschi, a restored Braniff Building--built in 1923 by the brothers who started their namesake airline--and a public park recycled from a pair of windswept plazas. The New York-based architecture firm of Rogers Marvel will incorporate features like green roofs, native plantings, and storm-water management to meet LEED standards. Sandridge, which is the youngest and smallest of the city's gas giants, is touting the project as the largest private downtown development in its history--for the time being, at least."
