In 2004, a flood damaged more then 60% of the property that comprised the Saint Elizabeth Ann Seton Parish in Carnegie, PA. We were retained to prepare a master plan that comprehensively analyzed all four church sites within the parish. It was determined that either a new church should be constructed at the St. Luke’s site or the existing church on that site be expanded. The above are study models that illustrate the new church option. Its design concept was to clearly differentiate the sacred from the service spaces. The sacred spaces are set at a 45-degree angle from the street grid and are enclosed with a roof that is supported by four large trusses, allowing for clearstory windows. The service spaces are single-story and adhere to the street grid, thereby defining the street edge. These two systems converge at a historic bell tower retained from the original church. The second phase is the construction of a new social hall. We designed the social hall with a small plaza between the buildings. A colonnade that connects all three buildings defines the social hall’s façade. This colonnade engages the plaza with stairs that extend the entire length of the plaza, creating an animated building edge and a place for people to interact. The third and final phase of the project is the renovation of the historic school building. The school, no longer in operation, is to be converted into a Parish Life Center.
