Nairn County Council Building, 4-6 Court House Lane, Nairn

The Nairn County Council Building, designed by Mackenzie and Matthews in 1847, is an Italianate single-storey structure featuring an asymmetrical five-bay range. The building is constructed from tooled ashlar with polished ashlar dressings and has rubble flanks. The southwest elevation, facing the street, has a round-headed doorway located near the center, which is set under an open square campanile in a pylon form. Each face of the campanile has a single round-headed and balustraded arch recessed into it. The building also features an eaves band, bracketed eaves, and a shallow pyramidal slate roof.

To the right, there is a wide gabled bay that includes a round-headed tripartite window with a bull's-eye window above it. The southeast elevation has three bays that are lit by round-headed windows. To the left, there are two round-headed windows, while the third bay has been blocked by a later two-bay wing. All windows and the doorway are connected by a band course, and the building is topped with tall chimney stacks and a slate roof.
