Danish architecture studio Bjarke Ingels Group (BIG) has announced plans to remodel Pittsburgh's Lower Hill district with new housing, retail and commercial space.
The project covers a 28-acre site and was once Pittsburgh's Civic Arena that was later demolished and replaced with the nearby Consol Energy Centre.
BIG plans to introduce 1,200 units of housing, along with 150 room hotels, 632,000ft² of office space, and 250,000ft² (23,225m² of commercial, retail and entertainment facilities.
The company is also planning to introduce a large green space that will pass through the centre of the development, while making use of the local topography.
With the project, BIG plans to connect the Hill District back to its downtown core.
The proposal also consists of individual buildings with functions bound by a network of accessible paths and triangular plazas.
Architect Magazine cited BIG founding partner Bjarke Ingels as saying: "The master plan for the Lower Hill District is created by supplementing the existing street grid with a new network of parks and paths shaped to optimise the sloping hill side for human accessibility for all generations.
"The paths are turned and twisted to always find a gentle sloping path, leading pedestrians and bicyclists comfortably up and down the hillside.
"The resulting urban fabric combines a green network of effortless circulation with a quirky character reminiscent of a historical downtown.
"Topography and accessibility are merging to create a unique new part of Pittsburgh."
