Mill House (Hamilton Kerr Institute) and Mill

Mill House, also known as the Hamilton Kerr Institute, is a building located on Mill Lane in Whittlesford. It was designed by Ebenezer Hollick, a miller who died in 1828, and features a brick structure dated 1763 near the entrance. The building has 19th-century and 1970s additions and alterations. It is constructed of red brick with gauged brick and limestone dressings, topped with plain tiled roofs.

The house is two storeys tall with attics and has a double pile plan, presenting an irregular five-bay facade. It features a plain parapet with gables at either end and stacks. A moulded brick cornice and a band separate the floors, and the plinth is also brick. The first floor is brick coursed with headers. The entrance is adorned with Doric pilasters and an entablature, while there are four ground floor and five first floor slightly recessed twelve-paned hung sash windows, each with segmental brick arched heads and stone console keys. Two hipped dormer windows are also present.

Inside, most details are from the 19th century, including two first floor eared wooden fireplaces. A late 18th-century white marble fireplace has been removed. The mill, which consists of two ranges connected by a cartway, has been modified for use as studios, a library, and living accommodation. Some corn bins remain in the attic, along with a pulley wheel, although other machinery has been removed.
