The Stable block at Uppark to the north west of the house

The Stable block at Uppark, located to the northwest of the house, was built around 1770 by Sir Matthew Fetherstonhaugh. It features a south wing that is the second of two balancing blocks. This south block is constructed of red brick and has three central window bays that project, topped with a pediment. The roof is hipped and covered with slate, featuring a turret cupola at the center. The building has two storeys and five windows.

Behind the south wing are two additional wings that form three sides of a courtyard. These wings, now known as Nos 1-4 National Trust flats and the Trust's Office, are also made of red brick with grey headers. The east wing has a central projection with a pediment above it, and it includes a round-headed archway flanked by similar blind arches. This wing also has five windows.
