The Co-op Food Store is expanding and renovating its building on South Park Street with designs by Studio Nexus Architects, authors of the recent Co-op at the roundabout on Lyme Road. A floor plan in the new booklet explaining the renovation (pdf) shows that the addition will bump out the South Park Street facade along most of its length.

The Park Street building, which sort of serves as a gatepost at the southeastern entrance to Hanover, was built in 1962 to the designs of E.H. & M.K. Hunter, a firm also known for Bradley/Gerry. (Lisa Mausolf’s history of midcentury Modernist architecture in New Hampshire (pdf) mentions a few area buildings and includes several designs by the Hunters around the state.)

The Co-op’s awkward Sixties charm seems to have been renovated out of it during the Eighties and Nineties. A neat and unexpected series of massing models on page 8 of the booklet shows the building’s evolution: by putting a shed-roofed apparent second story over the new entrance, the proposed addition will hint at the original building’s high forehead, now encased in accretions.
