Uist House consists of a self-contained, purpose built, three storey office building, understood to have been built in the late 1980s, within close proximity to Great Chesterford Railway Station (0.2 miles).

Internally, the office space is primarily open plan on the ground floor with a kitchenette incorporated at one end. Male and female WC are on the ground floor (including disabled). The first floor is a similar open plan layout. Both floors benefit from suspended ceilings with lighting incorporated into the panels. There is electric heating and three phase power in the property.

The second floor has angled ceilings, due to the gable roof and is suitable for storage.
