The team of CJS Architects/Fisher Associates was selected by the NWHOF to develop the master plan for the Center for Great Women, with the goal to transform the Mill into a showcase space with the intent to preserve the rich history of women's achievements through restoring the existing Mill and an creation of a new addition. Specifically, the renovation project includes the programming of 4 existing floors of the Mill building to host the museum’s educational programs, inductee area, research center, Mill history, special exhibits and artifact displays. The addition to the mill will serve as the Center’s Welcome Center and include a visual orientation area, reception, gift store and rest-rooms. The second floor will have a café and a roof terrace that will offer views of Seneca Falls and Erie Canal.

The Seneca Knitting Mill complex has seen over the course of its life span alterations to its buildings, site and waterway, with the exception to the Old Stone Mill. The masterplan keeps the Old Stone Mill as the central, iconic feature of the site. All proposed architectural elements will be inserted onto the site according to pre-existing building footprints, with an aesthetic of simple extruded forms in character with the orthogonal and regularly sited building that once existed.
